Best Aftermarket Exhaust For Atv: Compare 10 Fitment Options

#1 · Best Overall

1. PRO BAT Exhaust System

• Compatible with Vehicle Type: 50cc 70cc 90cc 110cc Quad Dirt Bike ATV
• Material: Metal

Best for: Small-displacement quad replacement.

Why it ranks #1: A complete pipe-and-muffler system targets 50cc–110cc quads and ATVs, with bolt-on installation and stated 32mm flange and 45mm mounting spacing.

The PRO BAT system’s listed 50cc–110cc range makes it a targeted option for small-displacement quads, dirt bikes, and ATVs rather than a general-size slip-on. Its bolt-on installation type and approximately 710 mm overall length give buyers practical details for planning a replacement around the existing engine and mounting layout.

The system is listed for 50cc, 70cc, 90cc, and 110cc quad, dirt-bike, and ATV applications, helping narrow compatibility by engine size. Its bolt-on installation type is intended to make fitting straightforward, and the product description likewise says installation is hassle-free. The approximately 510 mm pipe and 200 mm muffler lengths clarify how the 710 mm assembly is divided, while the 32 mm engine flange and 45 mm mounting-hole spacing are useful fit checks before replacement.

Skip it if you need a universal 38–51 mm slip-on for a larger pipe; Fast Pro’s muffler lists that wider connection range.

This suits owners of listed 50cc–110cc quads, dirt bikes, and ATVs replacing a complete pipe-and-muffler assembly. Compare the flange diameter, mounting-hole spacing, and overall length with the vehicle.

#2 · Broad Engine Fit

2. SHIQINHA 28mm Muffler

• Compatible with Vehicle Type: ATV, Go Kart, Motorcycle
• Material: Metal
• Weight: 0.74 kg

Best for: Small-engine clamp-kit replacement.

Why it ranks #2: Lists ATV, go-kart, and mini-bike use across several small-engine sizes, and includes an exhaust heat shield and three muffler clamps.

A broad small-engine application list is the SHIQINHA muffler’s key draw, spanning multiple Predator sizes, Honda GX engines, ATVs, minibikes, and go-karts. The included exhaust heat shield, silencer, clamps, and metal cable ties give buyers a defined set of installation-related components alongside the 1.1-inch muffler.

The listed applications include 50cc–125cc four-stroke engines, several small two-stroke sizes, and Predator engines from 79cc through 420cc, plus Honda GX160, GX200, and GX390. That range helps owners screen a small-engine ATV or minibike by engine type before installation. The package includes an exhaust heat shield, silencer, three exhaust clamps, and four metal cable ties; the strong clamps are described as fixing the pipe firmly. The 1.1-inch size remains the key connection checkpoint.

Skip it if you need a 38–51 mm universal connection; the LEIMO KPARTS carbon-fiber muffler is listed for that range and ATVs.

This targets small-engine ATV, minibike, and go-kart owners whose application appears in the supplied list and whose connection matches 1.1 inches. Use the included shield and clamps as installation components.

#3 · Small ATV Fit

3. RZEOZU 25-28mm Muffler

• Compatible with Vehicle Type: ATV, Go Kart, Lawn Mower, Motorcycle

Best for: Mini-bike and small-ATV fitment.

Why it ranks #3: Names numerous 50cc–125cc ATV applications, plus minibikes and engines including Predator 212; check the specific model exceptions before ordering.

The RZEOZU muffler lists an unusually broad set of small-bike, ATV, minibike, and engine applications, including several Coleman and Predator models. Its 25–28 mm slip-on sizing makes it a focused choice for owners checking smaller exhaust interfaces rather than shopping for a 38–51 mm universal muffler.

The supplied compatibility examples span pit bikes, small ATVs, lawn mowers, generators, Coleman minibikes, and Predator engines, so buyers can compare their machine against named applications. The title specifies a 25–28 mm slip-on muffler, providing a narrower sizing target than broad universal designs. That combination makes the listed model and interface checks central to installation planning. The product is supplied as a slip-on muffler; the provided details do not specify included clamps or a broader mounting kit, so buyers should plan around that stated component scope.

Skip it if you have a 38–51 mm exhaust pipe; the LEIMO KPARTS carbon-fiber muffler lists that broader range and ATV compatibility.

This suits owners of listed small ATVs, pit bikes, minibikes, or named engine applications with a matching 25–28 mm connection. Check the specific model listing and interface before planning the slip-on installation.

#4 · Low-RPM Design

4. ABCERRSI 28mm Muffler

• Weight: 1.2 lb

Best for: Small-pipe low-speed riding.

Why it ranks #4: Specifies a 28mm aperture and 22–32mm buckle range for dirt bikes and ATVs, with an adapter ring for 26mm or 30mm interfaces.

A built-in porous baffle and spiral airflow channel distinguish the ABCERRSI muffler, with listed torque optimization for 3,000–6,000 rpm and a 12% low-torque increase versus straight-through type. Its 28 mm aperture and adapter-ring support target smaller-pipe ATV and dirt-bike setups.

The 28 mm product aperture and 22–32 mm buckle range establish the main sizing checks, while the adapter ring supports 26 mm and 30 mm original interfaces. That combination can accommodate several listed small interfaces without relying on a broad 38–51 mm universal connection. The porous baffle and spiral airflow channel are stated to optimize torque at low and medium speeds, with a claimed 12% low-torque increase versus straight-through type. Its 260 mm length also gives buyers a defined muffler size to compare with available space.

Skip it if you need broad 38–51 mm pipe compatibility; the Fast Pro muffler lists that connection range for ATVs and quads.

This is for ATV or dirt-bike owners with a matching small interface who value the listed low- and mid-speed torque focus. Check the aperture, buckle range, and adapter support against the exhaust pipe.

5. Fast Pro Universal Muffler

• Compatible with Vehicle Type: Atv,Bike,Dirt,Dirt Bike,Motorcycle,Scooter
• Inlet Connection Size: 1.5 in
• Material: Aluminum, Stainless Steel, Titanium
• Weight: 3.3 lb

Best for: Mixed-vehicle pipe-size match.

Why it ranks #5: Explicitly lists ATVs and quads among compatible vehicles and accepts 38–51mm pipe diameters, but installation instructions are not included.

A 38–51 mm connection range is the Fast Pro muffler’s clearest advantage, letting riders consider one slip-on for an ATV, quad, dirt bike, street bike, or scooter with a matching pipe. Its 390 mm length gives buyers a concrete size to compare against their available exhaust space.

The stated 38–51 mm connection diameter is the key fit checkpoint: it spans several pipe sizes, while the listing names ATVs and quads among compatible vehicle types. At 390 mm long, the canister also has a specified length to assess against the bike’s exhaust layout. Aluminum, stainless steel, and titanium are listed materials, and hardware is included, giving a buyer mounting supplies alongside the pipe. Installation instructions are not included, so the work requires a separate fitting plan.

Skip it if you need a model-specific bolt-on kit; the listed connection range is universal rather than an ATV-specific mounting specification.

This suits an ATV or quad owner who can match a 38–51 mm pipe and accommodate a 390 mm muffler. Choose it for a universal slip-on approach, but account for the absent installation instructions.

6. LEIMO KPARTS Slip-On

• Compatible with Vehicle Type: Bike,Motorcycle,Dirt Bike,Scooter,Atv,Scooters
• Inlet Connection Size: 1.5 in
• Material: Aluminum, Stainless Steel
• Weight: 1.37 kg

Best for: Carbon-look universal slip-on.

Why it ranks #6: Lists ATVs and quads with 38–51mm pipes and includes a removable DB killer, though its broad universal fit requires careful diameter verification.

A removable DB killer gives the LEIMO KPARTS muffler a changeable sound setup, while its carbon-fiber finish supplies a distinct appearance. The 38–51 mm fit range is the practical anchor for ATV, quad, dirt-bike, and scooter owners checking whether this lightweight universal slip-on can connect to their existing pipe.

The stated 38–51 mm pipe range covers the listed ATV, quad, dirt-bike, street-bike, and scooter types, making pipe diameter the essential compatibility check. A removable DB killer offers a different sound effect by changing the insert configuration. Aluminum and stainless steel form the listed construction, and the product description says the combination reduces overall weight and resists corrosion and rust. Together, the broad vehicle list and slip-on format support buyers seeking a cross-style replacement, but the supplied information does not specify a vehicle-specific mounting kit.

Skip it if you need a small 28 mm outlet and low-to-midrange torque features; the ABCERRSI muffler lists those specifications instead.

This fits buyers seeking a carbon-fiber-look slip-on for an ATV or other listed bike with a 38–51 mm pipe. Check the connection and plan mounting around the universal format before ordering.

7. GY6 Black Exhaust System

• Compatible with Vehicle Type: Scooter
• Inlet Connection Size: 1.5 in
• Weight: 3.5 lb

Best for: Black GY6 system replacement.

Why it ranks #7: Designed for GY6 125cc, 150cc, and 200cc ATVs as well as scooters and mopeds; its 1.5-inch inlet limits it to matching setups.

A complete-system format for 125cc, 150cc, and 200cc GY6 engines makes this black Generic exhaust a focused replacement option for compatible scooters, mopeds, and ATVs. Its black-coated finish is described as resisting rust and wear, combining a stated surface benefit with the clean appearance of a matching black pipe and muffler.

The GY6 engine-family fitment and 125cc–200cc displacement range give owners a concrete compatibility screen for their ATV or other listed vehicle. The complete replacement system includes a black muffler and exhaust/header pipe, with a support bracket identified in the description, helping organize the parts needed for an exhaust change. Its coating is described as resisting rust and wear, while the system is engineered to optimize exhaust flow. The listing’s 1.5-inch inlet and outlet dimensions provide additional connection checks.

Skip it if you need a non-GY6 small-quad system; the PRO BAT exhaust is listed for 50cc–110cc ATVs and quads.

This is for a 125cc–200cc GY6 ATV, scooter, or moped owner replacing a full exhaust system and preferring a black finish. Verify the engine family and 1.5-inch connections.

#8

8. GY6 High Performance Exhaust

• Compatible with Vehicle Type: Scooter
• Inlet Connection Size: 1.5 in
• Weight: 3.5 lb

Best for: GY6 engine replacement.

Why it ranks #8: Lists GY6 125cc–200cc ATVs and a 1.5-inch inlet, but the product description centers on scooters and provides less ATV-specific detail.

GY6-specific fitment across 125cc, 150cc, and 200cc engines is this muffler’s strongest differentiator, narrowing the choice for owners of compatible ATVs, mopeds, and motorcycles. Its bolt-on replacement format is intended to simplify installation, while the listing also connects exhaust flow with engine efficiency and throttle response.

The stated GY6 compatibility covers 125cc, 150cc, and 200cc applications, giving owners a clear engine-family and displacement check before choosing this system. Its direct-replacement, bolt-on format is described as requiring minimal modifications, which can make a replacement workflow more straightforward. The product is also engineered to optimize exhaust flow, with the listing linking that feature to efficiency and throttle response. Heavy-duty construction is specified for high heat and demanding riding, relevant to regular use on a compatible machine.

Skip it if you have a non-GY6 ATV; the PRO BAT system is listed for 50cc–110cc quads and dirt bikes instead.

This is aimed at owners replacing an exhaust on a 125cc–200cc GY6 ATV or related vehicle who want a bolt-on format. Confirm the engine family and displacement match before choosing it.

#9

9. PACEWALKER Matt Black Muffler

• Compatible with Vehicle Type: Scooter
• Inlet Connection Size: 1.5 in
• Material: Aluminum
• Weight: 1.38 kg

Best for: Removable-insert scooter option.

Why it ranks #9: Its removable DB killer and 38–51mm connection could suit a matching ATV pipe, but the stated vehicle applications are motorcycles and scooters.

The removable DB killer is the defining feature of this PACEWALKER muffler, allowing a rider to change the sound effect by removing or fitting the insert. Its 365 mm overall length and 38–51 mm slip-on connection give scooter and motorcycle owners useful dimensions to check before installation.

The listed 38–51 mm connection supports use with various motorcycle and scooter exhaust pipes in that diameter range, while the 365 mm length helps assess space along the existing exhaust route. Supplied springs, hooks, and a universal connected pipe provide mounting-related components with the muffler. The removable DB killer changes the sound to a low, deep character when fitted as described. Although the title is broad, the supplied vehicle compatibility names scooters, so ATV owners lack explicit fitment support.

Skip it if you need listed ATV fitment; the LEIMO KPARTS carbon-fiber muffler explicitly includes ATVs and accepts 38–51 mm pipes.

This makes sense for a scooter or motorcycle owner seeking a removable sound insert and supplied connection hardware. Check the 365 mm length and pipe diameter; ATV-specific compatibility is not stated in the listing.

#10

10. PACEWALKER Grilled Blue Muffler

• Compatible with Vehicle Type: Motorcycle
• Inlet Connection Size: 38-51 millimeters
• Material: Stainless Steel, Titanium
• Weight: 1.5 kg

Best for: Adjustable-sound pipe match.

Why it ranks #10: The 38–51mm universal slip-on specification may match some setups, but its listed compatible vehicle type is motorcycle rather than ATV.

A removable DB killer gives the PACEWALKER slip-on a sound-adjustment option, so riders can change the muffler configuration rather than accept only one setup. Its 38–51 mm inlet range adds a practical pipe-size checkpoint for motorcycle or scooter owners considering this blue-finished titanium-alloy unit.

The 38–51 mm inlet range supports matching the muffler to a compatible motorcycle or scooter exhaust pipe, while its stainless-steel connector provides the listed connection material. A removable DB killer lets the owner alter the sound effect by changing the muffler’s configuration. The double-head baking-blue finish is described as rust-resistant and higher-strength, pairing its appearance with a stated surface benefit. The listing identifies motorcycle compatibility, not ATV fitment, so ATV shoppers should not assume this is their match.

Skip it if you need explicitly listed ATV compatibility; the LEIMO KPARTS carbon-fiber slip-on names ATVs and the same 38–51 mm pipe range.

This is for motorcycle or scooter riders seeking a removable sound insert and a blue-finished muffler, provided their pipe measures within the listed range. ATV buyers should favor a product with ATV compatibility stated.
