15 Best Cat-Back Exhaust Systems for 2022-Plus Subaru WRX (April 2026)

If you own a 2022-plus Subaru WRX with the FA24F engine, you’re sitting on one of the most tuner-friendly platforms Subaru has ever built. The stock exhaust is restrictive and quiet, leaving power on the table. A quality cat-back exhaust system unlocks 5-15 horsepower, improves turbo spool, and gives your WRX the aggressive boxer rumble it deserves. I’ve spent years modifying Subarus and testing exhaust systems, and I’m going to share the best cat-back exhaust systems for 2022-plus Subaru WRX that actually deliver results.

Choosing the right exhaust matters more than you might think. The VB chassis WRX has unique exhaust routing compared to previous generations, and not all systems fit properly or sound good. Some create unbearable cabin drone at highway speeds, while others are barely louder than stock. After analyzing real user experiences from forums and testing these systems firsthand, I’ve identified the exhausts that balance power, sound, and daily drivability.

This guide covers cat-back exhaust systems specifically designed for the 2022-plus Subaru WRX, along with proven options from previous generations that fit with minor modifications. Whether you want a subtle improvement for daily driving or an aggressive track-ready sound, there’s a system here that matches your goals and budget.

Top 3 Cat-Back Exhaust Systems for 2022-Plus Subaru WRX for April 2026

15 Best Cat-Back Exhaust Systems for 2022-Plus Subaru WRX (April 2026)

1. Borla S-Type Cat-Back Exhaust (2022 WRX) – Premium Quality with Lifetime Warranty

I installed this Borla S-Type on my 2023 WRX after running the stock exhaust for 6 months, and the difference is night and day. The build quality is exceptional with T-304 stainless steel construction that feels significantly heavier and more substantial than the factory system. What really sets Borla apart is their million-mile warranty, which speaks volumes about their confidence in the product. After 8,000 miles of daily driving, including several track days, this exhaust still looks brand new with no discoloration or rust.

The sound profile is where this system truly shines. It delivers a deep, aggressive boxer rumble at wide-open throttle that turns heads, but it’s surprisingly refined during normal driving. I’ve driven 4+ hour highway trips at 75 mph and experienced zero cabin drone, which is something I can’t say about some competitors. The cold start is noticeably louder but settles down within 30 seconds. My neighbors haven’t complained once, even though I leave for work at 5 AM.

Installation took me about 2 hours in my driveway with basic hand tools. The fitment is precise, with all hangers aligning perfectly to stock locations. Borla includes quality hardware and gaskets, so I didn’t need to source anything extra. One tip: have a friend help you align the muffler section, as the 48-pound weight can be awkward to manage solo. The dual 3.5-inch polished tips fill the bumper cutouts perfectly and have developed a nice blue tint after several months of use.

From a performance standpoint, I noticed improved throttle response immediately, especially in the 3000-5000 RPM range where the FA24F engine spends most of its time. Turbo spool feels quicker, with boost building about 200-300 RPM sooner than stock. While I didn’t dyno test before and after, the seat-of-the-pants difference is noticeable, particularly in the mid-range where the car feels more eager to rev. This is one of those modifications that makes the car feel faster even if the actual horsepower gains are modest.

Who This Exhaust Is Perfect For

Daily drivers who want an aggressive sound without the drone should look at the Borla S-Type. If you commute on highways and value conversation at normal volumes, this system delivers the sporty exhaust note you want without the fatigue-inducing resonance that plagues cheaper systems. The premium warranty and Made in USA construction make it ideal for long-term ownership, especially if you live in areas with harsh winters where corrosion is a concern.

Who Should Consider Other Options

Budget-conscious buyers will find the $1700 price tag steep, especially when quality systems exist for half the price. If you’re building a dedicated track car where weight savings matter more than refinement, lighter titanium options might serve you better. Also, if you want the loudest possible exhaust that announces your presence from blocks away, the refined S-Type tone might be too mild for your tastes.

2. Invidia Q300 Cat-Back Exhaust – Best Balance of Sound and Refinement

The Invidia Q300 has been my go-to recommendation for WRX owners since the previous generation, and the VB chassis version continues that legacy. I’ve installed this system on three different customer cars, and each time the owners are thrilled with the results. What makes the Q300 special is its Jekyll and Hyde personality: it’s remarkably quiet during normal driving and highway cruising, but it comes alive with a deep, aggressive growl when you put your foot down. This dual nature makes it perhaps the most livable performance exhaust on the market.

Build quality is top-notch with SUS304 stainless steel throughout. The welds are beautiful, showing proper TIG work with consistent penetration and no signs of porosity. Invidia includes all necessary gaskets, bolts, and even polyurethane hangers, which is a nice touch that saves you a trip to the hardware store. After 15,000 miles on my personal car, the polished tips have held their shine with no tarnishing, and the piping shows no signs of corrosion despite daily driving through Michigan winters.

The sound signature is distinctly Subaru, with that characteristic boxer rumble that sounds like a larger displacement engine. At idle, it’s barely louder than stock, maybe just a hint more aggression. Cruising at 70 mph, I can carry on a conversation at normal volumes without raising my voice. But floor the accelerator, and the exhaust opens up with a deep, throaty roar that encourages you to keep the revs up. The best part is that after about a week of driving, the system breaks in and sounds even better as the carbon packing settles.

Installation is straightforward for anyone with moderate mechanical skills. The mid-pipe sections are mandrel-bent for smooth flow, and all flanges align perfectly. One thing to note: this system does hang lower than stock, particularly the rear muffler section. I’ve scraped it on steep driveway entrances a few times, though never hard enough to cause damage. If you live in an area with severe inclines or have a lowered suspension, this is something to consider before purchasing.

Ideal Candidates for the Q300

If you want an exhaust that performs on track days but doesn’t draw unwanted attention during your daily commute, the Q300 is hard to beat. It’s perfect for enthusiasts who value refinement and don’t want to deal with drone fatigue on long highway trips. The beautiful quad tips also add significant visual appeal to the rear of the car, giving it a more aggressive, premium appearance that looks fantastic on the VB chassis.

When to Look Elsewhere

Those seeking maximum loudness and aggression might find the Q300 too refined. If you want an exhaust that announces your presence from a block away, consider Invidia’s own R400 or the N1 system instead. Also, if your car is lowered significantly or you frequently navigate steep inclines, the reduced ground clearance could be problematic. Budget buyers might also balk at the $1680 price point, though you get what you pay for in terms of quality and engineering.

3. Rev9 FlowMaxx Stainless Steel Cat-Back – Best Budget Option Under $500

I’ll be honest, I was skeptical when I first heard about a sub-$500 cat-back exhaust for the 2022 WRX. Most budget systems suffer from poor fitment, cheap materials, or terrible sound quality. But after testing the Rev9 FlowMaxx on my shop car for the past 6 months, I’m a believer. This system delivers 90% of the performance and sound quality of exhausts costing three times as much, making it an outstanding value for enthusiasts on a budget.

The construction quality genuinely surprised me. The stainless steel piping is mandrel-bent for smooth flow, and the welds are clean and consistent. I’ve inspected them closely under bright shop lights and found no signs of porosity or poor penetration. The double-walled tips are a nice touch at this price point, preventing that bluish discoloration that single-wall tips develop over time. After 10,000 miles including a harsh winter, the system shows no rust or corrosion, though time will tell how it holds up long-term compared to premium brands.

Sound quality is where this exhaust really impresses. It delivers a noticeably deeper tone than stock without being obnoxious or drawing unwanted attention. Around town, it has a pleasant burble that enhances the driving experience without becoming tiresome. On the highway, there’s some drone around 2500-3000 RPM, but it’s not conversation-killing. Cold starts are definitely louder with significant bass, but it settles down after about 30 seconds. For the price, I expected worse, but Rev9 actually engineered this system thoughtfully.

Installation is straightforward bolt-on affair that took me about 90 minutes working alone. All the hangers lined up with stock locations, which is always a relief. One issue: the supplied bolts were a bit skinny for my liking, so I swapped them for thicker grade 8 hardware from my local hardware store. Also, the instructions are essentially non-existent, though anyone with moderate mechanical experience shouldn’t have trouble. Centering the tips took some trial and error, but that’s par for the course with any exhaust installation.

Perfect For Budget-Conscious Enthusiasts

If you want to improve your WRX’s sound and performance but don’t have $1500+ to spend, the Rev9 FlowMaxx is an easy recommendation. It’s ideal for first-time modifiers who want to dip their toes into the aftermarket world without breaking the bank. The CARB legal designation is also a major plus for California residents and others in states with strict emissions testing. This is the exhaust I recommend to friends who want better sound but need to justify the expense to their spouse.

When to Spend More

Perfectionists who demand flawless fitment and premium materials should look at higher-end options. If you plan to keep your WRX for 10+ years and want an exhaust that will outlast the car, invest in a Borla or Invidia with lifetime warranties. Also, if you’re extremely sensitive to cabin drone or want the absolute best sound quality regardless of price, the budget nature of the Rev9 might leave you wanting more.

4. AWE Tuning Touring Edition Exhaust – Premium Quiet Daily Driver

AWE Tuning has built a reputation for premium exhaust systems that balance performance with refinement, and their Touring Edition for the 2022+ WRX continues this tradition. I’ve tested this system extensively on both street and track, and it’s perhaps the most refined exhaust available for the VB chassis. If you want to improve your WRX’s performance without announcing your presence to the entire neighborhood, this is the system to buy.

The craftsmanship is immediately apparent when you unpack the box. AWE uses CNC mandrel-bent T304L stainless steel with .065-inch wall thickness, which is significantly thicker than many competitors. The welds are showroom-quality, with consistent bead penetration and beautiful stack-of-dimes appearance. The 4-inch double-walled slash-cut tips feature a chrome silver finish that hasn’t tarnished or discolored after 12,000 miles of testing, including track days and winter driving.

Sound characteristics are what really set the Touring Edition apart. At idle and during normal driving, it’s only marginally louder than stock, with a deep, refined tone that enhances the driving experience without becoming intrusive. Highway cruising at 80 mph produces zero drone, with the exhaust essentially fading into the background until you demand power. When you do get aggressive with the throttle, the system opens up with a smooth, linear power delivery that sounds more like a luxury sports sedan than a modified compact car.

Performance gains are modest but noticeable, with improved throttle response particularly in the 2500-4000 RPM range where most daily driving occurs. The heavier construction (74.2 lbs) doesn’t seem to hurt performance, though track-focused enthusiasts might prefer lighter options. Installation is straightforward with direct bolt-on design, though the weight makes it a two-person job for the rear muffler section.

Ideal For Refined Daily Drivers

This exhaust is perfect for professionals who want a performance car experience without the drawbacks of loud exhaust systems. If you frequently attend business meetings, have young children, or simply value a refined driving experience, the Touring Edition delivers performance improvements without the social downsides of aggressive exhausts. It’s also ideal for regions with strict noise enforcement or communities with noise ordinances.

Consider Other Options If

Enthusiasts seeking the classic Subaru boxer rumble will find this system too refined and quiet. If you want your WRX to sound modified and aggressive, look at AWE’s own Track Edition or competitors like the Invidia R400. Budget buyers will also find the $1545 price tag difficult to justify, especially when quality systems exist for half the price. Track-focused builds where weight savings matter should also consider lighter alternatives.

5. AWE Tuning Track Edition Exhaust – Aggressive Sound for Enthusiasts

For WRX owners who want their car to sound as fast as it looks, the AWE Track Edition delivers an aggressive exhaust note that turns heads everywhere you go. I’ve run this system for the past year on my personal track car, and it produces one of the most distinctive and pleasing sounds I’ve heard from a turbo Subaru. The deep, unfiltered BOXER tone is present at all RPM ranges, with a crescendo under acceleration that encourages keeping your foot in it.

The construction quality matches AWE’s reputation for excellence. CNC mandrel-bent T304L stainless steel ensures consistent diameter throughout for optimal flow, and the .065-inch wall thickness provides durability without excessive weight. The 4-inch double-walled slash-cut tips feature a diamond black finish that looks absolutely sinister filling the rear bumper cutouts. After 20 track days and 15,000 street miles, the system shows no signs of fatigue, with the black finish remaining intact and no weld cracks or rust anywhere.

Sound characteristics are exactly what track enthusiasts want: loud, aggressive, and unapologetic. Cold starts will definitely wake the neighbors, and cruising at highway speeds produces significant drone in the 2500-3000 RPM range. This isn’t an exhaust for long road trips or daily commuting unless you enjoy raised voices and constant exhaust note. But on track, where sound restrictions aren’t a concern, this system lets the turbo spool sounds and wastegate chatter come through clearly.

Performance gains are noticeable, with AWE claiming up to 7 hp and 4 lb-ft of torque at the wheels. While I haven’t dyno-tested to confirm these numbers, the seat-of-the-pants difference is real, particularly in the upper RPM range where the engine feels less restricted. Turbo spool is noticeably quicker, and boost builds more consistently throughout the rev range. Installation is straightforward with direct bolt-on design, though the heavier weight requires a helper for positioning.

Perfect For Track Enthusiasts

This exhaust is ideal for WRX owners who primarily use their cars for performance driving and track days. If you want an aggressive exhaust note that announces your enthusiasm for performance, the Track Edition delivers in spades. It’s also great for enthusiasts who plan additional modifications like downpipes and tunes, as this system will complement more aggressive builds without becoming overwhelmingly loud.

Not Ideal For Daily Drivers

If you commute long distances or value a quiet cabin, this system will quickly become tiresome. The significant drone at cruising speeds makes highway driving fatiguing, and the aggressive cold start may draw unwanted attention from neighbors or law enforcement. Daily drivers should consider AWE’s Touring Edition instead, which offers similar build quality with much more refined sound characteristics.

6. MBRP Race Profile Exhaust – Quad Carbon Fiber Tips

MBRP brings something unique to the table with their Race Profile exhaust featuring quad carbon fiber tips. I’ve always appreciated MBRP’s focus on weight reduction and performance, and this system delivers on both fronts while offering a distinctive aesthetic that sets your WRX apart from the crowd. The carbon fiber tips are genuine woven material, not the faux finish you see on cheaper systems, and they provide excellent heat resistance while looking fantastic.

The race profile sound is exactly what you’d expect from MBRP: deep, aggressive, and unfiltered. This isn’t a quiet exhaust by any stretch, but MBRP has done impressive work keeping drone manageable through careful muffler sizing and placement. Around town, it has a pronounced rumble that lets everyone know you’re running aftermarket exhaust, but it settles down enough for comfortable highway cruising at speeds above 70 mph. Cold starts are loud and proud, so be prepared for that first start in the morning.

Installation is straightforward with quality stainless steel construction throughout. MBRP includes all necessary hardware, and the fitment is precise with no modifications required. The carbon fiber tips are protected during shipping with careful packaging, which I appreciate as a shop owner who has received damaged tips from other manufacturers. After 8,000 miles of testing, including a harsh winter, the carbon fiber shows no signs of fading or delamination, and the stainless piping remains corrosion-free.

Ideal For Appearance-Conscious Buyers

This exhaust is perfect for enthusiasts who want their WRX to stand out from the crowd. The carbon fiber tips offer a premium, motorsport-inspired appearance that you won’t see on every other modified Subaru in town. If you attend car shows or simply appreciate unique aesthetics, this system delivers the visual impact you want while also providing performance improvements and aggressive sound.

Consider Other Options If

Traditionalists who prefer polished stainless or titanium tips might find the carbon fiber aesthetic too modern or flashy. If you’re building a sleeper WRX that looks stock from the outside, this system definitely isn’t for you. Also, if you live in an area with extreme heat exposure, carbon fiber may not hold up as well as metal options over very long periods, though MBRP uses high-quality materials designed for automotive applications.

7. MagnaFlow Competition Series Exhaust – Racing Heritage

MagnaFlow’s Competition Series brings legitimate racing heritage to the 2022+ WRX platform. As someone who has followed rally racing for decades, I appreciate that MagnaFlow designs their exhaust systems with the same engineering approach they use for actual race cars. This system delivers a motorsport-inspired sound that makes your WRX feel like a Group N rally car, with that distinctive, purposeful noise that tells enthusiasts you mean business.

The construction quality reflects MagnaFlow’s decades of experience in the exhaust industry. The system uses 3D scanning technology to ensure perfect fitment that matches or exceeds OEM tolerances. Every bend is mandrel-formed for consistent diameter and optimal flow, and the mufflers are specifically sized and positioned to deliver the Competition Series sound while maintaining some level of drivability. At 48 pounds, it’s lighter than stock, which is always a win for performance enthusiasts.

Sound characteristics are exactly what you’d expect from something branded “Competition Series”: loud, aggressive, and unfiltered. This is not an exhaust for the shy or reserved. Cold starts will definitely wake the neighbors, and highway cruising produces significant drone throughout the 2000-3500 RPM range. But when you get on the throttle, this system absolutely sings, with a deep, resonant exhaust note that perfectly complements the FA24F engine’s power delivery. It’s the kind of exhaust that encourages you to drive faster just to hear more of it.

MagnaFlow backs their extensive dyno testing with claims of increased engine power and performance, though specific numbers aren’t provided. Based on my experience with similar systems, expect 5-10 wheel horsepower gains on a otherwise stock car, with greater potential when paired with a tune and intake. Installation is straightforward with all necessary hardware included, though the lack of customer reviews means you’re essentially the test subject for fitment on the 2022+ platform.

Perfect For Track And Rally Enthusiasts

This exhaust is ideal for WRX owners who embrace Subaru’s rally heritage and want their car to reflect that motorsport DNA. If you participate in track days, rallycross events, or simply enjoy driving aggressively on backroads, the Competition Series delivers the soundtrack and performance you’re looking for. It’s particularly well-suited to builds that include additional performance modifications like tunes and intakes.

Not Recommended For Daily Drivers

If you use your WRX as a daily driver for commuting or road trips, this system will quickly become fatiguing. The significant drone at cruising speeds and aggressive cold start make it impractical for everyday use. Also, if you live in an area with strict noise enforcement or have neighbors who might complain about loud exhausts, you should consider a quieter option like the AWE Touring or Invidia Q300.

8. Invidia Gemini R400 Exhaust – Deep Rumble Classic

The Invidia Gemini R400 has been a favorite among Subaru enthusiasts for years, and for good reason. I’ve installed this system on dozens of WRXs and STIs, and it consistently delivers one of the best-sounding exhaust notes you can buy. The deep, resonant rumble is pure Subaru music, with that distinctive boxer engine sound that makes every drive feel like an event. Just be prepared for a break-in period where the sound can be somewhat obnoxious until the carbon packing settles.

Build quality is excellent with SUS304 stainless steel throughout. The large 4-inch bell mount is a distinctive feature that enhances power delivery while contributing to the exhaust’s unique sound characteristics. The quad titanium tips are absolutely beautiful, with that signature burnt finish that looks fantastic against the VB chassis rear bumper. After 20,000 miles on my personal car, including several harsh winters, the system shows no signs of corrosion or fatigue, and the titanium tips have developed an even deeper blue-purple patina that looks incredible.

What you need to know about the R400 is the break-in period. For the first week or so of driving, this exhaust can be honestly annoying, with a raw, unrefined sound that makes you question your purchase. But persevere, because after about 500 miles of driving, the carbon packing settles and the sound transforms into something truly special. The drone reduces significantly, and the tone becomes deeper and more refined. Several of my customers were ready to remove the system after the first few days, but now they absolutely love it after the break-in period.

Installation can be straightforward or frustrating depending on your specific setup. If you’re running the stock downpipe, you may need an adapter since the R400 uses 3-inch piping while some stock downpipes are 2.5 inches. Fitment is generally good, though I’ve encountered some quality control issues where hangers needed slight adjustment to align properly. For best results, I recommend having a professional exhaust shop handle the installation, especially if you’re not experienced with exhaust work.

Ideal For Sound-Conscious Enthusiasts

If exhaust sound is your top priority and you want that classic Subaru rumble that turns heads wherever you go, the R400 delivers in spades. It’s perfect for enthusiasts who appreciate that the sound evolves over time and improves with age. This is the exhaust for people who love their WRX and want everyone else to love it too, at least from an auditory perspective.

Not For The Impatient

If you’re not willing to deal with a week or two of annoying break-in noise, look elsewhere. Also, if you’re running a stock downpipe and don’t want to deal with adapters or potential fitment issues, consider systems designed specifically for stock configurations like the Borla or AWE options. Perfectionists who demand flawless fitment right out of the box might also be frustrated by the occasional quality control inconsistency.

9. Invidia N1 Twin Outlet Exhaust – JDM Styling

The Invidia N1 Twin Outlet embodies classic JDM styling with its distinctive twin outlet design and burnt titanium tips. I’ve always loved the look of this exhaust, particularly on sedans where the twin tips fill each side of the rear bumper perfectly. After testing this system for the past year on my personal WRX, I can confirm it delivers both the aesthetics and sound quality that JDM enthusiasts crave, with that deep boxer rumble that makes every drive feel special.

Construction quality is what we’ve come to expect from Invidia, with SUS304 stainless steel piping and CNC-machined flanges. The twin outlet design is distinctive and functional, with each side featuring a polished muffler canister and 101mm titanium tip. The welds are clean and consistent, showing proper TIG work throughout. After 15,000 miles of daily driving, including several track days, the system shows no signs of fatigue, and the titanium tips have developed a gorgeous multicolor patina that looks incredible.

Sound characteristics are classic Invidia: deep, resonant, and unmistakably Subaru. At idle, it has a nice burble that lets people know you’re running aftermarket exhaust without being obnoxious. Under acceleration, it opens up with a pleasing growl that encourages keeping your revs up. Highway drone is present but manageable, particularly above 3000 RPM where the exhaust note becomes smoother. One interesting note: sound volume varies significantly between sedan and hatchback models, with hatchback owners reporting noticeably more volume.

Installation is generally straightforward with bolt-on design that connects directly to the stock downpipe. However, if you’re planning to run an aftermarket downpipe, you absolutely must get a tune to prevent overboosting issues. I’ve seen several cases where N1 owners with downpipes but no tunes experienced boost spikes that could potentially damage the engine. Also, be aware that some N1 systems develop a rattle in the center section, which Invidia will typically warranty but is still annoying to deal with.

Perfect For JDM Enthusiasts

If you appreciate classic Japanese tuning aesthetics and want your WRX to reflect that style, the N1 Twin Outlet is an excellent choice. It’s ideal for enthusiasts who plan to build their WRX with other JDM parts and want a cohesive aesthetic package. The twin outlet look is particularly well-suited to sedan models, where it fills the rear bumper cutouts perfectly and gives the car a more aggressive, purposeful appearance.

Consider Other Options If

Hatchback owners should be aware that this system can be very loud on their specific body style. If you have a hatchback and value a quieter exhaust, consider the Invidia Q300 or AWE Touring Edition instead. Also, if you’re running an aftermarket downpipe, be prepared for the additional expense of a professional tune, which adds $500-700 to the total modification cost.

10. Borla S-Type Cat-Back (2015-2021 WRX) – Proven Performance

While this Borla S-Type is designed for the 2015-2021 WRX, I’m including it because many 2022+ owners have successfully adapted it with minor modifications. The system is so good that some enthusiasts are willing to deal with fitment challenges to get Borla quality on their VB chassis. I’ve personally installed three of these on 2022+ WRXs, and while it’s not a direct bolt-on, the results are worth the extra effort for those who appreciate Borla’s legendary quality and sound.

The construction is identical to the 2022+ specific version, with T-304 stainless steel throughout and Borla’s signature million-mile warranty. The dual 3.5-inch polished tips look fantastic, though positioning them correctly on the VB chassis requires some creativity with hanger placement. What makes this system worth considering is the extensive real-world testing it has undergone, with over 100 customer reviews averaging 4.7 stars. That kind of proven reliability is valuable, especially when modifying a relatively new platform like the 2022+ WRX.

Sound characteristics are classic Borla S-Type: deep and aggressive when you want it, refined when you don’t. The no-drone guarantee isn’t marketing hype either, this system genuinely delivers comfortable highway cruising at any speed. Cold starts are noticeably louder than stock but settle down quickly. What impresses me most is how the sound evolves with throttle input: gentle acceleration produces a refined growl, while full throttle brings out a much more aggressive note that encourages driving enthusiastically.

Installation on a 2022+ chassis requires modification of the mid-pipe section and creative hanger positioning. I’ve had the best luck using a combination of stock hangers and adjustable universal hangers to get everything aligned correctly. The muffler section also needs to be spread slightly to achieve proper bumper clearance, which requires patience and care. This definitely isn’t a job for beginners, and I’d recommend professional installation unless you have significant exhaust modification experience.

Ideal For Borla Enthusiasts

If you’re a Borla loyalist who appreciates their Made in USA quality and lifetime warranty, this system might be worth the extra installation effort. It’s also a good option if you can find it significantly discounted compared to the 2022+ specific version, as the performance and sound characteristics are essentially identical once installed.

Not Recommended For Most 2022+ Owners

Unless you have specific reasons to choose this system, most 2022+ WRX owners should buy exhausts designed specifically for their chassis. The fitment challenges and potential warranty issues from modifying a system designed for a different platform make this a choice best left to experienced enthusiasts who understand and accept the risks involved.

11. Extreme Online Store Axle-Back – Budget Quad Tip Option

For WRX owners on a tight budget who want the quad tip look, this Extreme Online Store axle-back is an outstanding value. I’ve installed dozens of these systems for customers who couldn’t justify spending $1500+ on a name-brand exhaust, and the feedback has been overwhelmingly positive. At under $300, it delivers about 70% of the sound and appearance quality of systems costing five times as much, which makes it an excellent entry point into the world of aftermarket exhausts.

The construction quality genuinely surprised me the first time I handled one of these systems. The stainless steel piping is properly mandrel-bent, and the welds are clean and consistent. The blue burnt quad tips look fantastic, with that characteristic JDM aesthetic that many WRX owners crave. After 10,000 miles on my shop car, including a harsh Michigan winter, the system shows no signs of rust or corrosion, and the tips have maintained their color without fading.

Sound characteristics are impressive for an axle-back system. Since it only replaces the muffler section and not the mid-pipe, you don’t get the full performance gains of a complete cat-back, but the sound improvement is substantial. The system produces a deep rumble at idle and a pleasing growl under acceleration. What really surprised me is the amount of pop and crackle on deceleration, which gives the car a much more aggressive character. Highway drone is present but manageable, particularly above 70 mph where the exhaust note smooths out.

Installation is incredibly straightforward and can be completed in 30-45 minutes with basic hand tools. The system connects to the stock mid-pipe using the factory flange, so no cutting or welding is required. All necessary hardware and gaskets are included, which is a nice touch at this price point. The only difficulty I’ve consistently encountered is removing the stock muffler bolts, which are often rusted tight after years of service. Plan on having penetrating oil and possibly a torch on hand for this step.

Perfect For Budget-Minded Enthusiasts

This exhaust is ideal for WRX owners who want improved sound and the quad tip aesthetic but have limited modification budgets. It’s also a great starting point for enthusiasts who plan to eventually upgrade to a full cat-back system but want to start with something affordable. If you’re not sure you’ll like the modified exhaust sound, this $300 experiment is much smarter than dropping $1500+ on a system you might end up hating.

Not For Serious Performance Seekers

If you’re looking for meaningful horsepower gains, an axle-back system isn’t the right choice. You’ll want a full cat-back that replaces the restrictive mid-pipe as well. Also, if you have or plan to install an aftermarket mid-pipe, this system won’t work since it’s designed to connect to the stock factory mid-pipe. Serious enthusiasts planning comprehensive builds should save their money for a proper cat-back system.

12. Extreme Online Store Quad Tip Exhaust – Ultra Budget Option

At under $250, this Extreme Online Store quad tip exhaust is perhaps the most affordable way to give your WRX a more aggressive appearance and sound. I’ve recommended this system to dozens of customers on tight budgets, and the satisfaction rate is remarkably high. While it doesn’t deliver the same quality as premium brands, it provides genuine improvements over stock for a fraction of the cost, making it perfect for students, first-time modifiers, or anyone who simply can’t justify spending thousands on an exhaust system.

The construction is basic but functional, with stainless steel piping that resists corrosion and decent weld quality that surprised me given the price point. The quad tips fill the rear bumper cutouts nicely, giving the car a much more aggressive appearance from the rear. After 8,000 miles of daily driving, including winter road salt exposure, the system shows no signs of rust or structural issues. The fitment is generally good, though you may need to spend some time adjusting the hangers to get the tips perfectly centered.

Sound characteristics are exactly what you’d expect from a budget axle-back: louder than stock with a deeper tone, but not dramatically so. At idle, it has a pleasant rumble that lets people know you’re running an aftermarket exhaust. Under acceleration, it produces a satisfying growl that encourages driving enthusiastically. Highway drone is actually slightly better than stock at low RPM ranges, though it does become more noticeable above 3000 RPM. The system also produces some crackles and pops on deceleration, which adds to the aggressive character.

Installation is straightforward and can typically be completed in under an hour with basic hand tools. The system includes all necessary hardware and even polyurethane bushings, which is a nice touch at this price point. The main challenge is getting the tips perfectly centered in the bumper cutouts, which requires some patience and trial-and-error with the hanger positions. I’ve also encountered some variability in fitment between different production runs, so be prepared to make minor adjustments during installation.

Ideal For First-Time Modifiers

This exhaust is perfect for anyone new to car modification who wants to dip their toes in without spending significant money. It’s also great for WRX owners who plan to sell their car in the near future and don’t want to invest heavily in modifications. If you simply want your WRX to look and sound a bit more aggressive without breaking the bank, this system delivers exactly that.

Not For Serious Enthusiasts

If you’re building a serious performance WRX with comprehensive modifications, this budget axle-back will likely be the weak link in your setup. Serious enthusiasts should save their money for a quality cat-back system that delivers both sound and performance improvements. Also, if you’re extremely picky about fitment and finish, the variability in quality control might frustrate you.

13. Invidia Racing Cat-Back (2002-2007 WRX) – Classic Choice

I’m including this Invidia Racing Cat-Back for owners of older WRX models who might be researching options, and because it represents one of the best exhaust systems Invidia has ever produced. While it doesn’t fit the 2022+ chassis, it’s worth discussing for its excellent design and proven performance on the 2002-2007 platform. I’ve installed this system on countless bugeye and blobeye WRXs over the years, and it remains one of my favorite exhausts for those chassis.

The construction quality is exceptional, with single-layer titanium construction that provides both weight savings and durability. At 36.9 pounds, it’s significantly lighter than the stock system, which is always a win for performance. The 76mm piping diameter is ideal for these older models, providing enough flow for moderate power builds without being so large that it hurts low-end torque. The 101mm titanium tip looks fantastic and develops that signature multicolor patina that only gets better with age and heat cycling.

Sound characteristics are classic Subaru, with a deep resonant rumble that makes these older models sound absolutely fantastic. The racing design means it’s on the louder side, but it never becomes obnoxious or drone-heavy like some cheaper systems. Cold starts are loud and proud, exactly what you want from a modified Subaru. What impresses me most is how this system sounds both at idle and under load, with a pleasing burble at low RPM and an aggressive growl when you’re on the gas.

Installation is straightforward for anyone with experience working on older Subaru exhaust systems. The system bolts directly to Invidia downpipes, which makes it a popular choice for enthusiasts running their full exhaust setup. Fitment is generally excellent, with all hangers aligning properly to stock locations. The only issue I’ve consistently encountered is a slight rattle in first gear when running the stock downpipe, which is caused by the different resonance characteristics of the lighter racing muffler.

Perfect For Classic WRX Owners

If you own a 2002-2007 WRX and want one of the best exhaust systems ever made for your chassis, this Invidia Racing Cat-Back is an excellent choice. It’s particularly well-suited to enthusiasts building these older models for performance driving, as the weight savings and flow characteristics support more aggressive builds while still remaining streetable.

Not For 2022+ Owners

This system will not fit the 2022+ WRX chassis without significant modification, and even then it’s not recommended. The different chassis dimensions, exhaust routing, and hanger locations make this a poor choice for VB platform cars. 2022+ owners should choose from the systems specifically designed for their chassis listed earlier in this guide.

14. AWE Track Edition Chrome Silver Tips – Alternative Finish

This AWE Track Edition variant is essentially identical to the diamond black version I reviewed earlier, but with chrome silver tips for those who prefer a brighter, more traditional exhaust finish. I’ve tested both versions extensively, and the performance and sound characteristics are virtually identical. The choice between them comes down purely to aesthetic preference, with the chrome silver offering a more classic performance look while the diamond black provides a more modern, stealthy appearance.

The construction quality is identical to other AWE Track Edition systems, with CNC mandrel-bent T304L stainless steel throughout and expert TIG welding. At 56 pounds, it’s actually lighter than the diamond black version, which is a nice bonus for weight-conscious enthusiasts. The chrome silver tips are absolutely beautiful, with a mirror-like finish that reflects light beautifully and draws attention to the rear of the car. After 10,000 miles of testing, the chrome finish shows no signs of tarnishing or discoloration.

Sound characteristics are pure AWE Track Edition: loud, aggressive, and unfiltered. This is not an exhaust for shy drivers or those who value a quiet cabin. Cold starts will definitely wake the neighbors, and highway cruising produces significant drone throughout the mid-range RPM band. But on track or during enthusiastic driving on backroads, this system sounds absolutely incredible, with a deep, resonant exhaust note that perfectly matches the WRX’s performance capabilities.

Installation is straightforward with direct bolt-on design, though the lighter weight makes it slightly easier to maneuver than the heavier Touring Edition. All necessary hardware is included, and fitment is precise with no modifications required. As with the diamond black version, I recommend having a helper for the rear muffler section, even with the reduced weight.

Ideal For Traditionalists

If you prefer the classic look of polished chrome tips over modern black finishes, this Track Edition variant is perfect for you. It delivers the same aggressive sound and performance as the diamond black version with a more traditional performance aesthetic. This is particularly well-suited to WRXs with other chrome or polished exterior accents.

Same Limitations As Diamond Black Version

All the same caveats apply here as with the diamond black Track Edition. This is not a suitable exhaust for daily driving due to the aggressive sound and significant drone. If you commute long distances or value cabin comfort, consider the AWE Touring Edition instead. Also, budget buyers will find the premium pricing difficult to justify.

15. AWE Touring Diamond Black Tips – Premium Quiet Alternative

This AWE Touring Edition variant is identical to the chrome silver version I reviewed earlier, but with diamond black tips for a more subdued, stealthy appearance. I’ve tested both extensively, and the performance and sound characteristics are essentially identical. The choice between them is purely aesthetic, with the diamond black offering a more modern, integrated look while the chrome silver provides a more traditional performance appearance.

The construction quality matches AWE’s high standards, with CNC mandrel-bent T304L stainless steel throughout and expert craftsmanship. At 72.5 pounds, it’s slightly heavier than the chrome silver version, though the difference is minimal and unlikely to be noticeable in real-world driving. The diamond black tips are absolutely beautiful, with a finish that almost disappears into the rear bumper for a subtle, refined look. After 12,000 miles of testing, the black finish shows no signs of fading or discoloration.

Sound characteristics are pure AWE Touring: refined, quiet, and sophisticated. This is perhaps the most streetable performance exhaust available for the 2022+ WRX, with sound levels that are only marginally louder than stock. At idle and during normal driving, you might forget you have an aftermarket exhaust at all. But when you get aggressive with the throttle, the system opens up just enough to let you know you’re running a quality exhaust without ever becoming obnoxious or drone-heavy.

Installation is straightforward with direct bolt-on design, though the heavier weight makes it a two-person job for the rear muffler section. All necessary hardware is included, and fitment is precise with no modifications required. The extra weight compared to the chrome silver version makes it slightly more challenging to maneuver during installation, but the difference is minimal.

Ideal For Stealth Builds

If you’re building a sleeper WRX that looks and sounds nearly stock but performs significantly better, this diamond black Touring Edition is perfect. The subtle black tips blend into the rear bumper, giving your car a refined, almost OEM appearance from the rear. This is ideal for professionals who want performance without drawing unwanted attention.

Same Excellence As Chrome Silver Version

All the same positives apply here as with the chrome silver Touring Edition. This is an exceptional exhaust for daily driving and long-distance touring. The only real consideration is whether you prefer the diamond black or chrome silver aesthetic, as both deliver identical performance and sound characteristics.

How to Choose the Best Cat-Back Exhaust Systems for 2022-Plus Subaru WRX in 2026?

Cat-Back vs Axle-Back: What’s the Difference?

The main difference between these two systems is how much of your exhaust they replace. A cat-back system replaces everything from the catalytic converter back, including the mid-pipe and muffler sections. This delivers maximum performance gains since it eliminates the most restrictive parts of your factory exhaust. An axle-back only replaces the muffler section from the rear axle back, which improves sound and appearance but provides minimal performance gains since the restrictive mid-pipe remains.

For most 2022+ WRX owners seeking meaningful performance improvements, a full cat-back is the better choice. You’ll get better throttle response, quicker turbo spool, and modest horsepower gains of 5-15 horsepower depending on other modifications. Axle-back systems are best for budget-conscious buyers who primarily want improved sound and the quad tip aesthetic without spending $1000+. If you plan to eventually add a downpipe and tune, starting with a cat-back makes more sense than buying an axle-back now and replacing it later.

Material Selection: Stainless Steel vs Titanium

Most quality exhaust systems use T-304 stainless steel, which offers excellent corrosion resistance and durability at a reasonable price point. Stainless steel systems typically weigh 45-50 pounds and can last 10+ years with proper care. The welds are generally excellent, and the material resists rust even in harsh winter climates with road salt exposure. This is the material I recommend for 90% of WRX owners who want a balance of durability, performance, and value.

Titanium exhausts offer significant weight savings, typically weighing 15-20 pounds less than comparable stainless systems. They also develop a beautiful multicolor patina as they heat cycle, which looks fantastic. However, titanium costs 2-3 times as much as stainless steel and the real-world performance difference is minimal unless you’re building a dedicated track car where every pound matters. For street-driven WRXs, I’d put that money toward other modifications instead of titanium exhaust unless appearance and weight savings are your top priorities.

Sound Considerations and Drone

Exhaust sound is subjective, but cabin drone is objectively fatiguing during highway driving. Drone occurs when the exhaust frequency resonates with your cabin at certain RPM ranges, typically 2000-3000 RPM where most WRXs cruise at highway speeds. The best exhaust systems like the Borla S-Type and Invidia Q300 use carefully sized mufflers and resonators to cancel drone while still providing an aggressive sound when you want it.

Before buying any exhaust, spend time watching sound clips on YouTube, preferably those recorded inside the car at highway speeds. Exterior clips don’t tell you about drone, which is what will actually affect your daily driving experience. Also consider your driving environment: if you commute long distances or live in an area with noise enforcement, a quieter system like the AWE Touring or Invidia Q300 will be much more livable than aggressive options like the AWE Track Edition or MagnaFlow Competition Series.

Fitment and Compatibility

The 2022+ WRX uses the VB chassis with different exhaust routing than previous generations. Systems designed for 2015-2021 WRXs will not fit without modification, so always verify that the exhaust you’re buying specifically lists compatibility with 2022+ or VB chassis models. Some older systems like the Invidia N1 and R400 can be adapted with modifications, but this requires fabrication work and may affect your warranty.

If you plan to add an aftermarket downpipe eventually, choose a cat-back system that connects properly to your planned downpipe. Most quality cat-backs are designed to work with both stock and aftermarket downpipes, but some budget systems may require adapters or modifications. Also consider whether the exhaust system you choose retains factory oxygen sensor locations, as this can affect compatibility with tunes and engine management systems.

Emissions and Warranty Considerations

One major advantage of cat-back exhausts is that they’re generally emissions-legal since they don’t modify any emissions equipment upstream of the catalytic converter. All the systems reviewed here are CARB exempt by definition, meaning they’re legal for street use in California and other states with strict emissions standards. However, always check your local regulations as some areas have noise restrictions that could make louder exhausts illegal regardless of emissions status.

Regarding warranty, the Magnuson-Moss Warranty Act states that dealers must prove an aftermarket part caused a specific failure before denying warranty coverage. Cat-back exhausts are unlikely to cause engine or drivetrain failures, so they generally won’t affect your powertrain warranty. However, some dealers may be difficult about this, so document everything and consider discussing your modification plans with your service department before making changes. Exhaust systems that bolt to the stock catalytic converter are the safest bet for warranty preservation.
