1. TBOZZ 6 Inch Bull Horn Chrome Exhaust Stack – 60 Inch Length
6" Bull Horn Chrome Exhaust Stack,5"OD Reduced Bottom,60" Length
6in Bull Horn
5in OD Reduced Bottom
60in Length
Chrome Finish
Pros
- Eye-catching bull horn design
- Massive 60-inch presence
- Reduced 5in OD bottom for easy fit
- Durable chrome plating
Cons
- Limited stock availability
- Higher price point
This is the stack that gets people talking. The TBOZZ 6-inch bull horn chrome exhaust stack stands 60 inches tall with a dramatic bull horn opening at the top, and it earned the highest rating in our entire roundup at 4.9 stars. I have seen plenty of stacks in person, and this one has the kind of presence that completely changes a truck’s profile.
The 6-inch pipe reduces down to a 5-inch OD bottom, which is one of the most common fitment sizes for semi truck exhaust systems. That means it slides right into existing 5-inch piping without needing extra adapters or reducers. TBOZZ lists this as a bolt-on installation, and based on buyer feedback, the fitment is accurate.
Chrome quality is where this stack separates itself from cheaper options. TBOZZ uses a multi-layer chrome plating process over heavy gauge steel, and the result is a mirror finish that holds up through rain, road salt, and high-speed highway driving. Buyers specifically mention the chrome finish being flawless out of the box with no waves or imperfections.
At 60 inches, this is one of the taller stacks on the market. That extra height gives you the classic big rig look that many truckers want for show builds and custom Peterbilt or Kenworth projects. Just make sure you have the clearance for a 5-foot stack before pulling the trigger.
Fitment and Compatibility
The 5-inch OD reduced bottom fits most standard semi truck exhaust configurations without modification. This stack works well with Peterbilt 379 and 389 models, Kenworth W900, and Freightliner Classic builds. If your current exhaust uses a 5-inch OD pipe, this is a direct slide-in replacement.
Sold individually, so you will need to order two for a dual stack setup. The bull horn opening directs exhaust outward and slightly downward, which helps reduce soot buildup on the back of your cab compared to straight cut tops.
Long-Term Durability Expectations
Based on the chrome thickness and steel gauge used, this stack should hold its shine for several years with proper maintenance. Regular cleaning with chrome polish and avoiding abrasive cleaners will keep the mirror finish intact through all weather conditions.
TBOZZ backs their chrome stacks with quality construction rated for various weather conditions. With only 6 units typically in stock at any time, this is a product that moves fast when truckers discover it.
2. FGJQEFG 5-8 Inch Miter Cut Stainless Steel Exhaust Stack Tip
FGJQEFG 5 Inch Inlet 8 Inch Outlet Polished Stainless Steel Miter Angle Cut Diesel Smoker Exhaust Stack Tip Diesel Exhaust Tip(Stack Smokers 5" ID Inlet 36" Long)
5in Inlet to 8in Outlet
36in Length
T304 Stainless Steel
Miter Angle Cut
Pros
- Huge 8-inch outlet for aggressive look
- T304 stainless steel construction
- 230+ reviews with solid ratings
- Great value for the size
Cons
- Chrome can discolor with heat
- May arrive with shipping dents
The FGJQEFG miter cut exhaust stack is the best-selling product in this roundup with over 230 reviews, and it brings something different to the table. Instead of a standard chrome finish, this stack is built from polished T304 stainless steel with an aggressive miter angle cut at the top.
What caught my attention is the size range. The 5-inch inlet expands to an 8-inch outlet at the top, creating that wide smoker stack look that many diesel truck owners want. At 36 inches long, it is tall enough to clear most cabs without being unwieldy. The miter cut gives the opening a slash angle that looks more custom than a straight pipe cut.
Installation is rated as bolt-on, and the 5-inch inlet slides directly onto most standard diesel exhaust piping. Buyers report that the fitment is consistent and the stainless steel construction feels solid in hand. Several reviewers mention it produces a deeper exhaust growl compared to standard pipes, which is a nice bonus if you want your truck to sound as good as it looks.
The main complaint across reviews is heat discoloration. Some buyers report that the polished finish can turn a yellow or gold tint near the inlet where exhaust temperatures are highest. This is a known characteristic of stainless steel under extreme heat. If mirror perfection is your goal, you may want to look at chrome-plated options instead.
Sound and Performance Impact
The 8-inch outlet acts as a megaphone for your exhaust note, and many buyers specifically purchased this tip for the sound improvement. The miter cut design also helps direct exhaust gases outward rather than straight up, reducing under-cab soot accumulation.
Performance-wise, the expanded outlet reduces backpressure slightly compared to a straight 5-inch pipe. While the difference is minimal on stock engines, tuned diesels may see a small improvement in exhaust flow efficiency.
Shipping and Packaging Concerns
The most common negative feedback involves shipping damage. Because this is a large 36-inch metal pipe, it can arrive with dents or scratches if the packaging is insufficient. Check your stack immediately upon delivery and request a replacement if the finish is compromised.
Despite this concern, the overall value is hard to beat. You get a massive 8-inch stainless steel stack at a very competitive price, which is why it remains a top seller in the diesel exhaust category.
3. TBOZZ 5 Inch OD x 24 Inch Curved Chrome Exhaust Stack
5" OD×24" Curved Chrome Exhaust Stack Pipe
5in OD
24in Length
Curved Top
Chrome Plated Steel
Pros
- Most affordable option in the lineup
- 50 buyer reviews for confidence
- Curved top directs exhaust outward
- Simple bolt-on installation
Cons
- Shorter than typical semi stacks
- May need extension for full height
If you want chrome stacks without spending a fortune, this is where you start. The TBOZZ 5-inch curved chrome stack comes in at the lowest price point in our roundup while still maintaining a 4.7-star rating across 50 reviews. That combination of value and quality earned it our Budget Pick badge.
The 5-inch OD straight pipe measures 24 inches long with a curved top opening. This is shorter than most full-size semi truck stacks, which means it works best as either a replacement section, a tip extension, or a stack for a smaller truck build. The curved top design angles the exhaust opening outward, giving it a custom look without the full bull horn price tag.
Buyers consistently praise the chrome finish on this pipe. Multiple reviews mention that the plating is smooth, reflective, and free of the waves or ripples you sometimes see on budget chrome parts. The dimensions are reported as accurate to the listing, which means you can trust the sizing when planning your build.
Best Use Cases
This 24-inch stack works well as a replacement pipe for damaged factory exhaust sections or as part of a custom build where you already have a longer lower pipe. It is also a solid choice for medium-duty trucks, box trucks, and smaller diesel rigs that do not need a full 60-inch stack.
For a full-size semi truck build, you may want to pair this with an additional pipe section to reach the height you want. At this price, buying two sections still keeps you well under the cost of premium options.
Chrome Quality at This Price
TBOZZ uses the same chrome plating process across their curved stack line, so the finish quality matches their more expensive pipes. The 5-inch OD is one of the most common exhaust sizes, making this a versatile piece that fits many truck configurations without adapters.
With 86 percent of reviews giving five stars, the buyer consensus is that this stack delivers excellent quality for the price. It is the stack I would recommend to anyone testing the waters with chrome exhaust upgrades for the first time.
4. TBOZZ 6 Inch Bull Horn Chrome Stack – 36 Inch Length
Chrome Stack 6Inch (reduce to 5inch OD), 36inch Length Bull Horn
6in Bull Horn
5in OD Reduced Bottom
36in Length
Chrome Finish
Pros
- Aggressive bull horn opening
- Universal fit for many vehicle types
- 95 percent five-star reviews
- Great chrome finish quality
Cons
- Sold individually
- Shorter bull horn opening than 60in version
This is the shorter sibling of our Editor’s Choice pick. The TBOZZ 6-inch bull horn chrome stack at 36 inches gives you the same aggressive bull horn opening in a more manageable height. It carries an impressive 4.8-star rating from 17 reviews, with 95 percent of buyers awarding five stars.
The 6-inch pipe body reduces to a 5-inch OD bottom for standard fitment. What makes this version appealing is its versatility. TBOZZ lists it as a universal fit compatible with ATVs, buses, passenger cars, scooters, tractors, trucks, UTVs, and vans. While it is primarily designed for semi truck and heavy truck applications, the universal sizing means it can work on a wide range of builds.
I like the 36-inch length for trucks where a 60-inch stack would be impractical or illegal due to height restrictions. You still get the bull horn aesthetic that makes chrome exhaust stacks so visually striking, but in a package that fits under low clearances and bridges.
Versatility Across Vehicle Types
The universal fit rating means this stack is not limited to just semi trucks. Many buyers have installed it on modified pickup trucks, farm tractors, and even custom van builds. The 5-inch OD reduced bottom adapts easily to most 5-inch exhaust piping systems.
If you are running a diesel pickup and want the semi truck look, this 36-inch bull horn is an excellent middle ground between a standard exhaust tip and a full-size rig stack.
Weather Resistance and Finish
TBOZZ rates this stack as durable and reliable across various weather conditions. The chrome plating is designed to resist corrosion from rain, snow, and road salt. Several long-term owners report the chrome holding up well after a full year of daily driving.
The heavy gauge steel construction underneath the chrome provides structural rigidity that prevents bending or denting from road debris. This is a well-built stack at a fair price.
5. Cabtherlyn 5 Inch OD x 18 Inch Curved Chrome Exhaust Pipe
Cabtherlyn Exhaust Stack Pipe Curved Truck Pipe Heavy-Duty Steel Chrome, 5" OD x 18" Long Exhaust Pipe Truck Pipe
5in OD
18in Length
Heavy-Duty Steel Chrome
Curved Design
Pros
- Heavy-duty steel construction
- 12-month manufacturer warranty
- Excellent rust and corrosion resistance
- Great value at under $80
Cons
- Not Prime eligible
- Ships in 2-3 days
The Cabtherlyn curved chrome exhaust pipe is the newest entry in our roundup, but it has already made an impression with a 4.8-star rating from 11 reviews. What sets this pipe apart is the heavy-duty steel construction with chrome plating that the manufacturer specifically rates for harsh environments.
At 18 inches long with a 5-inch OD, this is the shortest pipe in our lineup. That makes it ideal as a connector section, a replacement for a damaged pipe segment, or a custom build component where you need a shorter curved piece. The curved design helps optimize exhaust flow by reducing sharp angles in your exhaust routing.
Cabtherlyn backs this pipe with a 12-month manufacturer warranty, which is more protection than most chrome exhaust products offer. The chrome-plated steel is described as rust-resistant and corrosion-resistant, and the heavy-duty construction means it can take more abuse than thinner gauge alternatives.
One thing to note is that this pipe is not Prime eligible and ships within 2 to 3 days rather than the 1 to 2 day delivery you get with Prime options. If you need a stack quickly for a repair or show deadline, factor in the slightly longer shipping window.
Compatibility and Sizing
The 5-inch OD fits most standard 5-inch diesel exhaust piping used on semi trucks and heavy duty pickups. Cabtherlyn notes compatibility with most 5 to 6 inch diesel intake pipes on trucks, so you have some flexibility in what this pipe connects to.
Buyers praise the chrome finish as being thick and even, with no thin spots or bubbling. The curved structure is designed to reduce backpressure and improve exhaust flow, which can translate to slightly better throttle response on tuned engines.
Warranty and Support
The 12-month warranty is a standout feature at this price. Most chrome exhaust products come with no warranty or a vague satisfaction guarantee. Cabtherlyn stands behind their manufacturing quality with a formal warranty period.
If you are building or repairing an exhaust system and want a heavy-duty curved section that will not rust through after one winter, this pipe deserves serious consideration.
6. TBOZZ 5 Inch OD x 36 Inch Curved Chrome Exhaust Stack
5" OD×36" Curved Chrome Exhaust Stack Pipe
5in OD
36in Length
Curved Top
Chrome Plated Steel
Pros
- 42 buyer reviews for confidence
- Full 36-inch height
- Solid chrome finish quality
- Good value for a full-length stack
Cons
- Some reports of chrome wear over time
- Finish may need regular polishing
This is the 36-inch big brother to our Budget Pick. The TBOZZ 5-inch curved chrome stack at 36 inches gives you full semi truck height at a price that remains very reasonable. With 42 reviews and a 4.7-star average, it is one of the most popular individual exhaust stacks in the TBOZZ lineup.
The 5-inch OD runs the full length of the pipe with no reducer, meaning you need a 5-inch exhaust system to match. The curved top angles the exhaust opening outward, which gives a more finished look than a straight cut pipe and helps direct exhaust gases away from the cab.
Buyers appreciate the value here. You get a full 3-foot chrome stack with quality plating at a fraction of what premium brands charge. The consensus is that this is a solid mid-range option for truckers who want real chrome stacks without the premium price tag.
Chrome Longevity Considerations
A few reviews mention that the chrome finish may show signs of wear over extended use, particularly in harsh winter conditions where road salt is present. This is a common issue with chrome-plated exhaust parts at any price point, not just budget options.
To maximize the life of the chrome finish, regular cleaning and polishing is recommended. Applying a chrome sealant after cleaning can add an extra layer of protection against salt and moisture. With proper care, this stack should maintain its shine for years.
Who Should Buy This Stack
This is the stack I would recommend for a working truck that needs chrome stacks but cannot justify spending on premium brands. It gives you the height, the look, and the quality you need for daily use at a price that makes sense for a working trucker’s budget.
The 5-inch OD straight pipe is one of the most common exhaust sizes in the trucking industry, so finding matching components and adapters is never a problem.
7. TBOZZ 7 Inch Bull Horn Chrome Exhaust Stack – 36 Inch Length
7" Bull Horn Chrome Exhaust Stack 5"OD Reduced Bottom,36" Length
7in Bull Horn
5in OD Reduced Bottom
36in Length
Chrome Finish
Pros
- Massive 7-inch bull horn opening
- Perfect for Mack and large truck builds
- Durable chrome plating
- Bolt-on installation
Cons
- Lower review count at 25
- Some quality variance reported
If you want the widest bull horn opening short of going to an 8-inch tip, the TBOZZ 7-inch bull horn chrome stack is your answer. The 7-inch bull horn opening sits atop a pipe that reduces to a 5-inch OD bottom, making it compatible with standard 5-inch exhaust systems while delivering an oversized visual impact.
This stack has found a particular following among Mack truck owners. Several reviews specifically mention perfect fitment on Mack models, which can be picky about exhaust components. At 36 inches long, it delivers a substantial presence without the extreme height of the 60-inch version.
The chrome quality earns praise from buyers who describe it as having a nice shine and solid material feel. TBOZZ uses the same chrome-over-steel construction across their bull horn line, so you get consistent plating quality whether you choose the 6-inch, 7-inch, or larger sizes.
With a 4.4-star rating across 25 reviews, this is a slightly more niche product. It appeals to truckers who want maximum visual impact from their bull horn opening without stepping up to custom 8-inch or larger fabricated stacks.
Best Truck Fitments
Beyond Mack trucks, this 7-inch bull horn works well on any semi truck or heavy duty truck running a 5-inch exhaust system. The reduced bottom makes it a direct slide-in replacement for standard 5-inch OD pipes.
The wider 7-inch opening creates a more dramatic visual statement than 6-inch bull horns while still being proportionate to most cab sizes. It is a sweet spot between aggressive styling and practical sizing.
Installation Notes
Bolt-on installation means you will not need welding equipment for this stack. However, you should verify that your existing exhaust clamps and mounting hardware are compatible with the 5-inch OD reduced bottom before installing.
The bull horn opening should be oriented to direct exhaust away from the cab and any nearby air intake or AC components. Proper orientation prevents soot buildup and keeps exhaust fumes from entering the cab area.
8. TBOZZ 6 Inch Curved Chrome Stack – Reducer to 5 Inch OD, 36 Inch Length
Chrome Stack 6Inch (reduce to 5inch OD), 36inch Length, Curved
6in to 5in OD Reducer
36in Length
Curved Design
Chrome Finish
Pros
- Built-in reducer from 6in to 5in
- Weighs 6.26 kg for solid construction
- 86 percent five-star reviews
- Curved top design
Cons
- Heavier than straight pipe alternatives
- Reducer built in so no size flexibility
The TBOZZ 6-inch curved chrome stack with a built-in reducer rounds out our lineup. This pipe starts at 6 inches and reduces down to a 5-inch OD bottom, giving you the wider 6-inch look up top with the standard 5-inch fitment at the bottom. No separate reducer coupling needed.
Weighing in at 6.26 kilograms, this is a solidly built pipe. The weight indicates a heavier gauge steel than some budget alternatives, which translates to better durability and resistance to vibration cracking. With 15 reviews and an 86 percent five-star rate, buyers are happy with the construction quality.
The curved top adds a touch of style compared to a plain straight cut pipe. While it is not as dramatic as a bull horn opening, the curve gives the exhaust a more finished and intentional look. It also helps direct exhaust gases at an angle rather than straight up.
Reducer Design Benefits
Having the reducer built into the pipe means one less connection point in your exhaust system. Fewer connections mean fewer potential leak points and a cleaner overall installation. The transition from 6 inches to 5 inches is smooth and gradual, which helps maintain exhaust flow efficiency.
This design is ideal for truckers who want a 6-inch visual profile but have a 5-inch exhaust system. It eliminates the need to buy a separate reducer coupling and keeps the installation simpler and more reliable.
Maintenance and Care
The chrome finish on this stack follows the same maintenance guidelines as all TBOZZ chrome products. Clean regularly with mild soap and water, avoid abrasive cleaners, and apply chrome polish periodically to maintain the mirror shine.
The heavier steel construction means this pipe is less likely to dent from road debris compared to thinner gauge alternatives. For truckers running daily routes on rough highways, that extra thickness makes a real difference in longevity.
How to Choose the Best Semi Truck Exhaust Stacks
Choosing the right exhaust stack comes down to diameter, material, style, and fitment. Whether you are building a show truck or replacing a work truck’s damaged exhaust, these factors will determine how happy you are with the result. If you are also shopping for complementary exhaust components, check our guide on weld-on exhaust tips for more options.
Stack Diameter Sizing Guide
Diameter is the most important spec to get right. Most semi truck exhaust systems use 5-inch piping as the standard, which is why so many of the stacks in our roundup feature a 5-inch OD reduced bottom. Here is a quick breakdown of common stack diameters:
5-inch stacks are the most common size for semi trucks. They match standard factory exhaust piping and provide adequate flow for most diesel engines. If your truck currently runs a 5-inch system, this is your easiest fitment path.
6-inch stacks give you a wider visual profile while still being practical for highway use. Most 6-inch stacks reduce to a 5-inch bottom for compatibility with standard systems. The wider top creates a bigger visual statement without requiring a complete exhaust system change.
7-inch and 8-inch stacks are for truckers who want maximum visual impact. These are typically used on show trucks and custom builds where appearance is the top priority. The larger openings can slightly alter exhaust note and flow characteristics.
Chrome vs Stainless Steel Materials
The material debate comes down to appearance versus practicality. Chrome-plated steel gives you that classic mirror shine that most truckers associate with custom stacks. The plating process involves multiple layers of chrome over a steel core, creating a reflective surface that looks incredible when polished.
Chrome does require maintenance to keep its shine. Road salt, brake dust, and weather exposure can dull the finish over time. Regular cleaning and polishing with quality chrome care products will keep chrome stacks looking new for years.
Stainless steel, like the T304 used in the FGJQEFG stack, is more resistant to rust and discoloration than chrome. It does not require the same level of maintenance, but the finish is more of a brushed silver than a mirror shine. Some stainless steel stacks can develop a gold or yellow tint near high-heat areas.
For show trucks and garage-kept rigs, chrome is the traditional choice. For work trucks that see daily duty in all weather conditions, stainless steel may offer better long-term durability with less maintenance. You can learn more about material differences in our guide to stainless steel exhaust tips.
One-Piece vs Two-Piece Stack Construction
One-piece stacks are single continuous pipes with no joints or connections in the middle. They are simpler to install, have fewer potential leak points, and generally look cleaner. Most of the stacks in our roundup are one-piece designs.
Two-piece stacks consist of an upper and lower section that connect with a coupling or clamp. They are easier to ship and transport, and they allow you to adjust the overall height by choosing different upper sections. The tradeoff is an extra connection point that can potentially leak or come loose over time.
Stack Top Styles Explained
Bull horn tops flare outward and slightly downward, creating a horn-like shape. This is the most dramatic and attention-grabbing style. Bull horn stacks are popular on show trucks and custom builds that want maximum visual impact.
Curved tops have a gentler angle than bull horns, directing exhaust outward at a moderate angle. They offer a custom look without being as flashy as bull horns. Curved tops are the most versatile style and work on both work trucks and show builds.
Miter cut tops feature a straight angled cut at the opening, creating a slash effect. This style looks more modern and aggressive. The miter cut is popular on diesel smoker builds and trucks with performance exhaust systems.
Flat tops are simply straight cut pipes with no angle or curve. They offer a clean, industrial look and are often used on working trucks where function matters more than form. Many truckers also pair their stacks with other accessories like fifth wheel hitches for trucks for a complete rig setup.
Installation Considerations
Most chrome exhaust stacks are designed for bolt-on installation using standard exhaust clamps. Before purchasing, measure your existing exhaust pipe diameter carefully to ensure proper fitment. Remember that OD refers to outer diameter and ID refers to inner diameter, and the difference matters when matching pipes.
If you are replacing existing stacks, the process is usually straightforward. Remove the old pipe by loosening the clamps, clean the mounting area, slide the new stack into position, and tighten the clamps. For new installations or custom builds, you may need additional hardware like brackets, hangers, and reducers.
Always check that your stack height clears bridges, low overhangs, and garage doors. A 60-inch stack on a tall cab can exceed legal height limits in some jurisdictions. For daily driver trucks, consider whether you also need cargo protection solutions like truck caps alongside your exhaust upgrade.
Durability and Weather Resistance
Forum discussions on trucking sites like TheTruckersReport consistently highlight chrome peeling and rusting as the top pain points with aftermarket exhaust stacks. The key to avoiding these issues is choosing stacks with thick chrome plating over heavy gauge steel.
Look for products that specifically mention weather resistance and durable construction. The TBOZZ and Cabtherlyn stacks in our roundup both emphasize their ability to withstand various weather conditions. Products with manufacturer warranties, like the Cabtherlyn pipe with its 12-month coverage, offer additional peace of mind.
Real-world reports from truckers indicate that proper maintenance makes the biggest difference in longevity. Washing salt and grime off your stacks regularly, applying chrome polish, and addressing any chips or scratches immediately will extend the life of any chrome exhaust product regardless of price point.
