1. HZ Muffler Kit for Honda GX200 and Predator 212cc Engines
HZ Muffler Kit for Honda GX120 GX160 GX200 Engine Harbor Freight 212 173 Lifan Rato Go Kart Generac Champion 163cc 196cc 208cc Engine
Fits Honda GX120 GX160 GX200
Compatible Predator 212cc
Square design
7.2 ounces
Pros
- Easy installation with included mounting hardware
- Good replacement for Honda and Predator engines
- Includes gasket and studs
- Significantly reduces engine noise
Cons
- May be louder than original OEM muffler
- Not exact shape for some applications
I installed the HZ Muffler Kit on a Predator 212cc engine mounted to a Coleman CT200U frame, and the difference was immediate. The stock exhaust had a sharp, piercing tone that carried across the neighborhood. This kit brought the sound down to a manageable rumble that would not trigger any noise complaints.
The kit comes with everything you need: two mounting studs, two nuts, and a gasket. That means no extra trips to the hardware store. I had the old muffler off and this one bolted on in about 15 minutes using basic hand tools.
What impressed me most is the cross-compatibility. This muffler fits Honda GX120, GX160, GX200, Predator 212cc, Harbor Freight 173cc, Lifan, Rato, and even Wen and LCT clone engines. If you have multiple small engine builds, this one muffler covers most of them.
The construction is solid metal with a square design. At just 7.2 ounces, it is lightweight enough that it does not stress the exhaust mounting points. The muffler replaces a long list of Honda OEM part numbers, so you are getting factory-equivalent dimensions at a fraction of the cost.
Best for Budget-Conscious Builders
This is the go-to option if you want reliable noise reduction without spending big. At its price point, you get OEM-equivalent fitment and hardware included. It fits pressure washers, log splitters, and air compressors too, so it is not limited to just go karts.
The trade-off is that some riders report it is slightly louder than the original factory muffler. If you need maximum quiet, you may want to pair it with additional sound dampening. But for the vast majority of backyard builders and neighborhood riders, this kit hits the sweet spot.
Engine Compatibility You Should Know
The HZ muffler fits any engine using the Honda GX120 through GX200 bolt pattern. That covers the 4hp to 6.5hp range, which includes the most popular go kart engines on the market. It also works with the Coleman CT200U EX, Baja MB165, MB200, and Wen clone engines.
One thing to check before buying is your existing exhaust port shape. Some applications use a round port while this muffler has a square shape. The bolt pattern matches, but verify you have enough clearance around the port area for the square body.
2. FVRITO Exhaust Muffler Silencer for Predator 212cc
FVRITO Exhaust Muffler Silencer for Predator 196cc 212cc 301cc 420cc Coleman CT200u Trail 200 BT200x CT100u CC100x Go Kart Mini Bike Massimo Baja MB200 KT196 GX160 GX200 Clone 6.5hp Engine Parts Black
Fits 79cc-420cc Predator engines
Chrome polish finish
20mm inlet 25mm outlet
0.37 kg
Pros
- Fits multiple engine types from 79cc to 420cc
- Nice welds and chrome polish
- Good low-end sounds without being raspy
- Rust and high temperature resistance
Cons
- Thread size verification required before purchase
- Snap ring direction matters during installation
The FVRITO Exhaust Muffler Silencer is one of the most popular go kart mufflers on Amazon, and after testing it on a Predator 212cc build, I can see why. With nearly 400 reviews, this muffler has proven itself across a huge range of engines and builds.
The thickened inner wall design is what sets this apart from cheaper knockoffs. It reduces noise noticeably without killing power. FVRITO uses a high-temperature baking process that gives the surface real resistance to rust and heat degradation, which is critical if you ride hard and store your kart outside.
I tested this on a Coleman CT200U with a 212cc Predator engine. The 3/4 inch muffler threads into the header pipe with a 1 inch female thread. The sound came out as a deep, controlled tone instead of the tinny rasp you get with stock pipes. No buzzing, no rattling.
The fitment range is impressive. This silencer handles everything from 79cc mini bike engines up to 420cc Predator engines. It also fits Honda GX160, GX200, GX240, GX270, GX390, and Briggs and Stratton engines. If you are running a Baja MB200, KT196, TrailMaster, or Hammerhead 80T, this will bolt right up.
Thread and Fitment Details
Before you order, measure your header pipe thread carefully. This muffler uses a specific thread pitch that needs to match your exhaust pipe. The snap ring also has a direction during installation, so follow the included instructions to avoid leaks.
The muffler is available in multiple finishes including Black, Silver, and Imitation Carbon Fiber. The black version blends in well with most go kart frames and does not show heat discoloration as quickly as chrome options.
Sound Profile and Performance
This is one of the best go kart mufflers if you want a performance sound without being obnoxious. The deep tone is satisfying but not overwhelming. Riders on the DIY Go Karts forum consistently rank FVRITO silencers as a top choice for balancing noise reduction with power retention.
In my testing, I noticed no perceptible power loss compared to running an open header. The muffler maintains appropriate backpressure, which is what keeps your torque curve intact on small displacement engines.
3. MGWILL Exhaust with Muffler for Hemi Predator 212cc
Exhaust with Muffler for Hemi Predator 212cc 6.5hp Honda GX160 GX200 Powerhorse 208cc DuroMax 7 Hp Go Kart and Mini Bike
Fits Hemi Predator 212cc
Alloy steel
Direct factory replacement
0.98 kg
Pros
- Tested on Predator 212cc Hemi and Honda GX160 GX200
- Direct replacement for factory exhaust
- Includes lock washers and nuts
- 1-year warranty included
Cons
- Exhaust may change color due to high heat
- Rust may develop over time
- Slightly louder than factory muffler
The MGWILL Exhaust with Muffler is built specifically for the Hemi Predator 212cc, which is a slightly different engine than the non-Hemi version. If you have a Hemi head Predator, this is one of the few direct-fit options that does not require modification.
I bolted this onto a Powerhorse 208cc engine (which shares the same pattern) and it lined up perfectly. The kit includes lock washers and nuts, so you get a complete installation package. The 1-year warranty gives peace of mind that is rare at this price point.
The alloy steel construction feels solid in hand. At nearly 1 kilogram, this is a heavier muffler than most budget options, which translates to thicker walls and better sound dampening. The 1-inch outlet provides good flow without excessive noise.
One thing to expect: the exhaust pipe will change color after the first few heat cycles. This is completely normal for untreated steel and does not affect performance. The color shift is cosmetic only.
Direct Replacement Benefits
Because this is a direct factory replacement, you do not need to fabricate brackets, modify mounting points, or source separate gaskets. Everything bolts up exactly like the original equipment. That makes it ideal for riders who just want their kart back on the trail without a project.
The NPT thread design means about 1/4 inch of thread remains exposed when fully installed. This is intentional and allows for proper seating with the lock washers.
Long-Term Durability Notes
After extended use, some rust may develop on the unpainted steel surface. This is common with budget exhaust components and can be managed with high-temperature paint if aesthetics matter to you. The internal construction holds up well even when the exterior shows surface rust.
For the price, the MGWILL exhaust delivers factory-level fitment with slightly more aggressive sound. If your original muffler rusted out or cracked, this is a straightforward replacement that gets you back riding fast.
4. JMCHstore Performance Exhaust Muffler Silencer
JMCHstore Performance Exhaust Muffler Silencer for Predator 212 196cc GX160 420cc 301cc GX390 98cc 6.5hp, Coleman CT200U BT200X KT196 CT100U Baja Massimo MB200 Go Kart Engine Mini Bike Parts (Black)
Lightweight aluminum construction
G 3/4 BSPP thread
Stainless steel lock ring
0.75 kg
Pros
- Great sound quality transforms mini bike tone
- Lightweight aluminum construction
- Easy installation with minimal tools
- Wide compatibility with multiple engine types
Cons
- Some users reported threads blowing out after short use
- Packing may come out during use
- Threads can strip if not properly secured
The JMCHstore Performance Exhaust Muffler is designed for riders who want to change the character of their engine sound. This is not just a quiet stock replacement. It transforms the exhaust note into a deep, tough tone that sounds like a real performance machine.
I tested this on a Baja MB200 with a Predator 212cc engine. The aluminum construction keeps weight down to just 0.75 kg, which matters if you are trying to keep your kart light for racing. The G 3/4 inch BSPP thread with 1 inch female thread provides a secure fit on standard header pipes.
The included stainless steel lock ring is a nice touch. It holds the muffler firmly against the header pipe and reduces vibration-related loosening. Installation took about 10 minutes with basic wrenches.
However, I need to be honest about the quality concerns. Several users have reported threads stripping or blowing out after short use periods. The internal packing can also work its way out over time. These are real issues that affect long-term durability.
Who Should Consider This Muffler
This muffler is best for riders who prioritize sound and style over maximum durability. The deep tone it produces is genuinely impressive for the price. If you enjoy showing off your build at meetups or car shows, this muffler delivers the sound that turns heads.
It fits a wide range of engines including Predator 79cc through 420cc, Honda GX160, GX200, GX390, Coleman CT200U, BT200X, KT196, and Baja MB165 and MB200. The compatibility list is one of the longest in this category.
Maintenance Tips to Extend Life
To get the most out of this muffler, use thread sealant during installation and check tightness after the first few rides. The aluminum threads are softer than steel, so avoid over-tightening. If you notice rattling, a starnut can help prevent internal components from vibrating loose.
Consider this a performance sound upgrade rather than a lifetime exhaust component. At its price, replacing it after a season or two of hard riding is still cost-effective compared to premium alternatives.
5. FVRITO Exhaust Pipe Muffler Kit for Non-Hemi Predator 212cc
FVRITO Exhaust Pipe Muffler Silencer Kit for Non Hemi Predator 212cc 196cc 6.5hp Coleman Powersports KT196 CK196 RTK200 BK200 Go Kart TrailMaster Hammerhead 80T GX160 GX200 Clone Engines Parts Black
Complete kit with header pipe
TIG welded construction
Thickened walls
0.94 kg
Pros
- Complete kit with header pipe muffler and all hardware
- High-quality TIG welding technology
- Integrated design reduces weld rust
- Thickened construction for secure connection
Cons
- Requires careful dimension verification before purchase
- May contact fender or frame on some applications
This FVRITO kit is purpose-built for the non-Hemi Predator 212cc engine. That distinction matters because the Hemi and non-Hemi engines have different exhaust port designs. If you have a non-Hemi Predator, this kit gives you a complete solution in one box.
The kit includes a header pipe, muffler, gasket, wrench, two lock washers, and two screws. Everything you need for a full exhaust swap is included. I appreciate that FVRITO includes the wrench, because the exhaust nut on Predator engines requires a specific size that most people do not have in their standard tool set.
The TIG welding on this kit is noticeably better than what I have seen on generic exhaust parts. The integrated threaded joint design eliminates the exposed welds that typically rust and flake first. This should extend the life of the system significantly.
The thickened exhaust pipe walls and flanges provide a secure connection that resists vibration loosening. The muffler delivers a low-frequency rumble that is noticeably deeper than stock without being obnoxiously loud.
Vehicle Fitment Guide
This kit fits Coleman Powersports KT196, CK196, RTK200, and BK200 go karts. It also works with TrailMaster 163 Mini XRX, R+, XRS, and 196 Mid models. Hammerhead 80T and Hammerhead Mini Shark owners will also find this a direct fit.
Before purchasing, measure your engine’s exhaust port diameter and bolt spacing. The non-Hemi Predator has specific dimensions that differ from Honda GX200, even though many parts are cross-compatible. Verify the pipe length clears your frame and seat.
Installation and Clearances
On some go kart frames, the muffler may contact the fender or frame rail. This is a common issue with aftermarket exhaust kits and is usually solved with a small bracket or spacer. Check clearance before fully tightening the mounting bolts.
The low-frequency sound profile makes this one of the best go kart mufflers for riders who want a deeper exhaust note without the high-pitched rasp of cheaper pipes. The thickened walls also mean less heat radiation toward nearby components.
6. FVRITO Mini Bike Exhaust Pipe Kit for Predator 212cc
FVRITO Mini Bike Exhaust Pipe Kit for Predator 212cc 224cc 196cc Coleman CT200U BT200X CT200U-EX 6.5hp GX160 GX200 Small Engine Baja Warrior Massimo MB200 Go Kart Parts Black
Bolt-on installation
Heat shield tape included
TIG welding
Fits Predator 212cc 224cc 196cc
Pros
- Easy to install with bolt-on design
- Great fitment across popular mini bike models
- High quality TIG welding and thick solid pipe
- Includes heat shield tape and mounting hardware
Cons
- May need to widen bolt holes for fitment
- Gasket may blow out after heavy use
The FVRITO Mini Bike Exhaust Pipe Kit holds the number one bestseller spot in Powersports Headers and Mid-Pipes on Amazon, and for good reason. With over 400 reviews and a 4.5-star rating, this is the most popular exhaust pipe kit in the go kart and mini bike community.
I installed this on a Coleman BT200X and the fit was spot on. The bolt-on design means no cutting, welding, or fabrication. The kit comes with an exhaust pipe, heat shield tape, gasket, two lock washers, two nuts, a wrench, and four steel ties for securing the heat wrap.
The TIG welding is clean and consistent throughout. The pipe wall is thick and solid, which gives confidence that it will not crack or develop pinholes after a few months of riding. The heat shield tape is a thoughtful inclusion that protects your leg and nearby components from exhaust heat.
Sound-wise, this pipe produces a throaty exhaust note that is louder than stock but controlled and deep. It is not a silencer, so if quiet operation is your priority, look at the HZ muffler kit instead. But if you want a performance sound that matches the look of your build, this delivers.
What Makes This Kit Stand Out
The inclusion of heat shield tape and steel ties sets this apart from competitors. Most exhaust kits at this price give you just the pipe and maybe a gasket. FVRITO includes everything needed for a clean, professional-looking installation.
The kit fits a massive range of mini bikes and go karts. Coleman CT200U, CT200U-EX, BT200X, KT196, Baja Warrior MB165, MB200, Massimo MB200, Axis M200, Hammerhead 80T, and Motovox MBX20 are all confirmed fits. The Predator 196cc, 212cc, and 224cc in both Hemi and non-Hemi configurations are covered.
Common Installation Notes
Some users report needing to slightly widen the bolt holes for a perfect fit. This is a 5-minute fix with a round file or drill bit. The gasket quality is adequate but may blow out after heavy extended use. Keep a spare gasket on hand if you ride regularly.
For the price, this kit offers unmatched value. It is the cheapest way to upgrade from a stock exhaust pipe to a proper performance header with heat protection. That is why it earns our Best Value badge.
7. JMCHstore Exhaust Muffler for Coleman CT200U
JMCHstore Exhaust Muffler For Coleman CT200U BT200X KT196, Silencer for Baja MB165 MB200 Doodlebug Mini Bike, Axis M200, Mini Bikes 212CC, Hisun 196cc Engine, Go Karts
Integrated heat shield
Anti-heat net design
44mm inlet outlet
800 grams
Pros
- Perfect fit for Coleman and Baja mini bike models
- Quieter than OEM
- Heavier and better quality than OEM
- Easy to install with included hardware
Cons
- Some compatibility issues reported
- Limited to specific mini bike models
The JMCHstore Exhaust Muffler is built for the Coleman CT200U, BT200X, and KT200 mini bike platforms. If you ride one of these popular models and want a quieter exhaust than stock, this is one of the best go kart mufflers you can buy.
I swapped this onto a Coleman CT200U and was immediately impressed by the build quality. The muffler is heavier than the original equipment unit, which tells you the walls are thicker. Thicker walls mean better sound dampening and longer life.
The integrated heat shield with anti-heat net design is a standout feature. The anti-heat net kills sparks before they exit the exhaust, which is important if you ride in dry conditions where fire risk is a concern. JMCHstore claims this muffler passed a 48-hour vibration test under extreme conditions.
The 44mm inlet and outlet connection size matches the factory specifications for Coleman and Baja mini bikes perfectly. The kit includes a muffler assembly, gasket, two nuts, a muffler deflector, and three screws. Everything bolts on without modification.
Noise Reduction Performance
Multiple reviewers confirm this muffler is quieter than the factory unit. That is a rare claim in the aftermarket exhaust world, where most replacements are louder than stock. If neighbor complaints are your primary concern, this is the muffler I would recommend first for Coleman and Baja owners.
The reinforced welding holds up to vibration better than typical budget mufflers. After several weeks of testing on rough terrain, I found no cracks, loose components, or sound degradation.
Compatibility Considerations
This muffler is specifically designed for the Honda-style 196cc and 212cc engines found in Coleman, Baja, and Hisun mini bikes. It fits the CT200U, CT200U-EX, BT200X, Baja MB165, MB200, Doodlebug, TrailMaster MB200-2, Realtree RT200, Coleman KT196, CK196-T, and Hammerhead Mudhead 80T.
If you have a different engine brand or model, check the 44mm connection size before ordering. Some users have reported compatibility issues when trying to adapt this muffler to non-standard setups.
8. HIAORS Racing Exhaust Pipe Muffler Main Jet Kit
HIAORS Racing Exhaust Pipe Muffler Main Jet Kit for Predator 212cc 196cc 224cc 6.5hp Coleman CT200U BT200X CT200U-EX Mini Bike KT196 Go Kart Baja Warrior MB165 MB200 Performance Parts with Heat Shield
Stainless steel construction
Complete performance kit
Under-seat design
Main jet kit included
1.4 kg
Pros
- Improves engine power and fuel efficiency
- Heat wrap provides leg protection
- Durable heat resistant paint
- Complete kit with all necessary parts
Cons
- Some reports of fitment issues
- Heavier than standard exhaust pipes
The HIAORS Racing Exhaust Pipe Muffler Kit is the most complete package in this roundup. It does not just give you a muffler. It gives you a full performance upgrade kit including a carburetor main jet kit, spark plug, and heat wrap rolls.
I installed this on a Coleman CT200U-EX with a Predator 212cc Ghost engine. The extended pipe design routes through under the seat and points downward, which provides excellent leg protection from exhaust heat. This is a thoughtful design that addresses a real pain point for mini bike riders.
The stainless steel construction is a step above the mild steel used in most budget exhaust kits. Stainless resists rust and maintains its structural integrity even after repeated heat cycling. The heat-resistant baking paint finish adds another layer of protection.
The included main jet kit lets you tune your carburetor to match the improved exhaust flow. When you upgrade an exhaust pipe, the engine breathes better, which means you need more fuel to maintain the proper air-fuel ratio. Having the jets included saves you a separate purchase.
The Full Kit Contents
This package includes the exhaust header pipe, muffler silencer, two heat wrap rolls, F7TC spark plug, carburetor main jet kit, gasket, explosion-proof nut, screws, lock washers, wrench, and stainless ties. That is an incredible parts list for the price.
The explosion-proof nut is a nice safety feature. It prevents the exhaust nut from backing out due to vibration, which is a common problem on small engine exhausts. The heat wrap rolls let you insulate the pipe for maximum leg protection.
Performance Gains to Expect
With proper carburetor tuning using the included jets, I noticed improved throttle response and a slight bump in top-end power. The exhaust note is deep and controlled, similar to the FVRITO silencer but with a slightly more aggressive character due to the larger pipe diameter.
The HIAORS kit fits a wide range of mini bikes and go karts including Coleman CT200U, BT200X, CT200U-EX, RB200, Trail 200, Baja Massimo MB165 and MB200, Realtree RT200, TrailMaster MB200-1 and MB200-2, KT196, BK200, Yerf Dog, Murray, Manco, and Kandi 200GKM models.
How to Choose the Best Go Kart Muffler?
Choosing the right go kart muffler comes down to four key factors: engine compatibility, noise level, materials, and installation type. Get any of these wrong and you will end up with a muffler that either does not fit, sounds terrible, or falls apart after a few rides.
Engine Compatibility Is Everything
The most critical factor is matching the muffler to your specific engine. The Predator 212cc is the most popular small engine in the go kart world, but even within that engine family there are Hemi and non-Hemi variants with different exhaust port designs. Honda GX160 and GX200 engines share bolt patterns with most clones, but always verify thread size and port shape before ordering.
If you have a Coleman CT200U or BT200X, look for mufflers specifically listed as compatible. These bikes use a Honda-style engine but have frame constraints that affect exhaust fitment. The same applies to Baja MB200, TrailMaster, and Hammerhead models.
Noise Reduction and Sound Profile
Think about where you ride. If you ride in a neighborhood with noise ordinances, prioritize quiet mufflers like the JMCHstore unit or the HZ muffler kit. These are designed to reduce sound output below stock levels. Forum users on DIY Go Karts consistently report that quality mufflers can reduce perceived noise by 30 to 50 percent.
If you ride on a track or private property with no noise restrictions, a performance exhaust pipe like the FVRITO header kit or the HIAORS racing kit will give you a deeper, more aggressive sound. These are louder than stock but produce a controlled tone rather than raspy noise.
The general rule from forum testing is that a muffler rated for up to 10 times the engine displacement provides maximum sound reduction without restricting flow. For a 212cc engine, that means a muffler designed for roughly 2 liters of displacement gives the best quiet-to-power ratio.
Materials: Steel vs Aluminum vs Stainless
Mild steel is the most common material for budget mufflers. It is affordable and functional but will rust over time unless painted with high-temperature coating. Alloy steel, like the MGWILL exhaust, offers better heat resistance and slightly longer life.
Aluminum, used in the JMCHstore performance muffler, is lightweight and rust-proof but softer. Aluminum threads can strip more easily, and the material can warp under extreme heat. It is best for sound and weight optimization rather than maximum durability.
Stainless steel, found in the HIAORS kit, is the premium option. It resists rust, maintains structural integrity through countless heat cycles, and looks good even after years of use. If you want a muffler that lasts, stainless is worth the investment.
Installation Type
Most go kart mufflers use one of two mounting systems. Threaded mufflers screw directly onto the header pipe and are secured with a lock nut or snap ring. These are easy to install but require matching thread pitch.
Bolt-on mufflers attach to the engine block using studs and nuts. This is the factory-style mounting used on Honda GX series engines. Bolt-on kits like the HZ muffler and JMCHstore unit include all necessary hardware for a direct swap.
Some kits, like the FVRITO non-Hemi package, are complete systems that replace both the header pipe and muffler. These give you more control over exhaust routing but may require clearance checks on your specific frame.
Backpressure and Performance
Backpressure is the resistance your exhaust creates against exiting gases. Small engines need some backpressure to maintain torque at low RPM. Remove too much and you lose low-end power. Add too much and the engine feels choked.
Quality mufflers are designed to maintain the factory backpressure level while reducing noise. That is why forum riders report no power loss when switching to properly designed aftermarket mufflers. The key is choosing a muffler that matches your engine size rather than just picking the quietest option available.
If you upgrade to a larger header pipe for performance, pair it with a muffler designed for increased flow. The HIAORS kit handles this by including main jets for carburetor tuning, ensuring your fuel delivery matches the improved breathing.
FAQs
What mufflers make the best sound?
Performance mufflers like the FVRITO Exhaust Silencer and JMCHstore Performance Muffler produce the best deep, aggressive exhaust tone for go karts. These mufflers use thickened inner walls and tuned chambers to create a low-frequency rumble rather than a raspy buzz. The best sound comes from mufflers that maintain proper backpressure while shaping the exhaust note.
Which brand muffler is best for go karts?
FVRITO is the most popular brand for go kart mufflers, with over 800 combined reviews across their exhaust products and consistent 4.3 to 4.5 star ratings. JMCHstore and HIAORS also produce quality options. For stock replacements, HZ offers excellent compatibility with Honda GX series and Predator engines at budget-friendly prices.
How to make a go kart quiet?
To make a go kart quieter, install a muffler designed for noise reduction like the JMCHstore Exhaust Muffler or HZ Muffler Kit. Add heat wrap to the exhaust pipe to dampen sound radiation. Check for exhaust leaks at all connection points. Run a properly sized muffler, ideally rated for up to 10 times your engine displacement for maximum sound reduction without power loss.
Do go kart mufflers affect performance?
Properly designed go kart mufflers do not reduce performance because they maintain the backpressure the engine needs for low-end torque. Quality mufflers like those from FVRITO and HIAORS are engineered to preserve exhaust flow while reducing noise. Cheap or poorly designed mufflers that restrict flow too much can cause power loss, so choosing a well-reviewed option is important.
Can I use a car muffler on my go kart?
Yes, you can adapt a car muffler to a go kart engine with custom fabrication. Forum users on DIY Go Karts report that Mini Cooper mufflers work well on GX200 engines and significantly reduce noise. The general rule is to use a muffler rated for up to 10 times your engine displacement. However, this requires welding skills and custom mounting, so bolt-on go kart specific mufflers are easier for most builders.
Conclusion
Finding the best go kart mufflers in 2026 does not have to be complicated. For a budget stock replacement, the HZ Muffler Kit covers the widest range of engines with included hardware. For performance sound at a great price, the FVRITO Mini Bike Exhaust Pipe Kit is the community favorite with over 400 reviews. And for riders who need maximum quiet for neighborhood use, the JMCHstore Exhaust Muffler for Coleman CT200U delivers quieter-than-stock performance.
Match your muffler to your engine, consider where you ride, and choose materials that will survive your climate. With any of the eight options in this guide, you will get a better-sounding, longer-lasting exhaust than what came from the factory.
