Best Exhaust For Dirt Bike: Compare 10 Fitment Options

#1 · Best Overall

1. GREHUA 28mm Exhaust Muffler

• Compatible with Vehicle Type: Motorcycle
• Material Type: Metal
• Inlet Connection Size: 28 millimeters
• Outlet Connection Size: 28 millimeters

Best for: 28mm Chinese pit-bike replacement.

Why it ranks #1: Its stated fitment spans compatible 50cc to 125cc pit bikes and names CRF50, XR50, SSR110, SSR125, DB10, and DB14 models, with 28mm connections.

A 28mm inlet and outlet are the defining measurements of the GREHUA muffler, giving owners a concrete starting point for checking a replacement against a small pit-bike exhaust connection. Its listed fitment spans 50cc to 125cc machines and names several familiar Chinese-brand and Honda mini-bike models.

The 28mm connections keep the key interface measurement clear, while the stated 50cc, 70cc, 90cc, 110cc, and 125cc range covers a broad small-bike displacement spread. Named compatibility includes CRF50 and XR50, SSR110 and SSR125, Taotao DB10 and DB14, plus numerous Chinese-brand bikes. That model list helps narrow a fit check before installation, but it is not universal: the listing specifically excludes Apollo RFZ 125 and other Honda models beyond those named.

Skip it if you need a 38mm slip-on for a larger connection; JFG RACING's 38mm exhaust is a better match to check.

For owners of listed small-displacement pit bikes, the GREHUA offers a clearly specified 28mm connection and broad named fitment. Keep its exclusions in view, especially if your machine is an Apollo RFZ 125 or another unlisted Honda.

#2 · Best Complete System

2. FVRITO High Performance Exhaust

• Compatible with Vehicle Type: Bike,Dirt Bike
• Material Type: Aluminum
• Inlet Connection Size: 1.26 in
• Outlet Connection Size: 28 millimeters

Best for: Complete one-piece pit-bike system.

Why it ranks #2: This one-piece assembly lists fitment for numerous Chinese 70cc to 125cc bikes, including CRF50, SSR, Taotao, Coolster, and Apollo DBx models.

The FVRITO is described as a complete one-piece exhaust system, a useful distinction for pit-bike owners seeking more than a muffler alone. Its named fitments span numerous 70cc–125cc Chinese bikes and selected CRF and XR models, with a 28mm outlet connection specified for checking the exhaust interface.

The one-piece system format can simplify shopping for a replacement by bringing the exhaust assembly together, while the 1.26-inch inlet and 28mm outlet give two connection measurements to compare. Its extensive fitment list covers selected CRF50, XR50, CRF70, Apollo DBx14/DBx18, SSR, Tao Tao, and many Chinese 70cc–125cc bikes. The listing also names exclusions, including Apollo RFZ 125 and several Honda models, so model checking matters before installation.

Skip it if you own an Apollo RFZ 125 or excluded Honda model; GREHUA's listing also excludes RFZ 125, so seek a model-specific alternative.

This suits riders of listed 70cc–125cc pit bikes seeking a one-piece system with stated connection dimensions. Check the detailed exclusions carefully, especially for Apollo and Honda models, before selecting it.

#3 · Best Hardware Bundle

3. YYCKE 28mm Exhaust Kit

• Compatible with Vehicle Type: Bike,Motorcycle
• Material Type: Aluminum
• Inlet Connection Size: 1.49 in

Best for: 28mm assembly-kit replacement.

Why it ranks #3: The 28mm kit includes a head pipe, muffler, clip, rubber gasket, two gaskets, and screw kit for listed 90cc to 125cc pit bikes.

The YYCKE package lists a muffler, head pipe, metal clip, gaskets, and screw kit, making its assembly contents a practical differentiator for owners replacing several exhaust pieces together. Its 28mm head and 45mm eye-to-eye measurement also give buyers specific dimensions for a pit-bike fit check.

The listed muffler and head pipe, plus a metal clip, black rubber gasket, two gaskets, and screw kit, put several installation pieces in one package. That can reduce separate parts sourcing when replacing an assembly, while the 28mm head and 45mm eye-to-eye measurement provide useful comparison points. Fitment names 90cc, 110cc, and 125cc pit bikes alongside CRF50, SSR, Baja, Coolster, and others. The aluminum construction is specified; matching the listed dimensions remains important.

Skip it if you need a 47cc–50cc two-stroke mini-bike exhaust; YLQYYH lists that smaller engine application.

The YYCKE suits owners of listed 90cc–125cc pit bikes who want several assembly and fastening pieces together. Use its 28mm head and 45mm spacing as fit checks; it is not listed for mini-bike engines.

#4 · Best Mini 2-Stroke

4. YLQYYH Mini Bike Exhaust

• Compatible with Vehicle Type: Motorcycle
• Inlet Connection Size: 1.53 in
• Outlet Connection Size: 39 millimeters

Best for: 47–50cc two-stroke mini-bike.

Why it ranks #4: Specifically listed for 47cc, 49cc, and 50cc mini dirt bikes, this option also gives a 1.53-inch bolt spacing to check before purchase.

A 1.53-inch bolt spacing gives the YLQYYH mini-bike exhaust a useful mounting measurement, while its title and description target 47cc, 49cc, and 50cc two-stroke machines. That combination makes it a narrowly focused replacement candidate for mini dirt-bike owners checking both engine class and mounting points.

The product is identified for a 50cc mini dirt bike, with the title extending the stated application to 47cc and 49cc two-stroke motorcycles. Its 1.53-inch bolt spacing, also given as 39mm, supplies a specific mounting check before installation. The specifications list a 1.53-inch inlet and 39mm outlet connection, giving additional dimensions to compare. This compact-engine focus is useful for a targeted search, but the supplied information does not name larger dirt-bike applications.

Skip it if you ride a 110cc or 125cc pit bike; EOPOAYI's muffler is titled for those engine sizes.

For a 47cc–50cc two-stroke mini dirt-bike owner, the YLQYYH listing provides mounting and connection measurements to check before fitting. Its stated mini-bike scope makes it a poor match for larger-displacement applications.

5. SHIQINHA 28mm Exhaust Muffler

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

Best for: Heat-shielded small-engine exhaust.

Why it ranks #5: The listing names 110cc and 125cc four-stroke fitment and includes a heat shield, silencer, clamps, and metal cable ties.

An included exhaust heat shield is the SHIQINHA muffler's most practical differentiator: the listing says it blocks high-temperature exhaust gas from radiating directly toward a rider's legs or plastic parts. Its stated applications extend beyond pit bikes to mini bikes, ATVs, go-karts, lawn mowers, and generators.

The heat shield addresses a specific exposure concern by blocking direct radiation from hot exhaust gas toward legs or nearby plastic parts, according to the listing. Its stated 1.1-inch fitment covers several small OHV engines as well as 110cc and 125cc four-stroke applications, across pit bikes, ATVs, go-karts, lawn mowers, and generators. Included clamps and metal cable ties offer mounting pieces for varied setups. The broad application list means buyers still need to match their engine and exhaust arrangement.

Skip it if you need a stated outlet dimension; YYCKE lists a 28mm head and a 45mm eye-to-eye measurement.

This suits small-engine owners seeking a muffler with a heat shield across several vehicle types, including pit bikes and go-karts. Check the engine and mounting arrangement carefully, since no outlet size is provided.

6. EOPOAYI 1.1-Inch Muffler

• Compatible with Vehicle Type: ATV, Motorcycle
• Material Type: Metal
• Inlet Connection Size: 1.1 in

Best for: Lightweight 110cc–125cc pit-bike option.

Why it ranks #6: This metal slip-on is listed for 110cc and 125cc pit dirt bikes and weighs 0.68 kg, though detailed model fitment is not provided.

At 0.68kg, the EOPOAYI muffler has a notably low listed weight, and its title targets 110cc and 125cc pit dirt bikes. A 1.1-inch inlet provides the main fit measurement, making this a focused option for owners of those small-displacement machines checking that connection size.

The 1.1-inch inlet is the key dimension to compare with the existing exhaust connection, while the title identifies 110cc and 125cc pit dirt bikes as its intended application. Its listed 0.68kg weight gives buyers a concrete mass figure when considering replacement-part handling. The specifications identify metal construction and an exhaust muffler as the included component. Since no outlet dimension or named bike models are supplied, this listing supports a narrower fit check than a model-specific kit.

Skip it if you need a stated outlet measurement; JFG RACING gives both inlet and outlet sizes as 38mm.

The EOPOAYI is suited to a 110cc or 125cc pit-bike owner who values a stated 0.68kg weight and has a 1.1-inch inlet to match. Its missing outlet dimension limits the available fit information.

7. JFG RACING Full Slip-On Exhaust

• Compatible with Vehicle Type: Bike,Dirt Bike,Motorcycle
• Material Type: Aluminum, Stainless Steel, Titanium
• Inlet Connection Size: 38 millimeters
• Outlet Connection Size: 38 millimeters

Best for: 38mm named-model slip-on.

Why it ranks #7: A 38mm connection and named fitment for HAWK 250, CRF230F, CRF150F, and TBR7 suit riders seeking a model-specific larger-bike option.

A 38mm inlet and outlet give the JFG RACING slip-on a specific connection size, while its title names HAWK 250, CRF230F, CRF150F, and TBR7. That combination makes it a focused candidate for riders checking those models and that exhaust interface rather than seeking a broadly sized muffler.

The 38mm inlet and outlet are useful measurements to compare with the bike's exhaust connection before planning a slip-on replacement. Its named compatibility—HAWK 250, CRF230F, CRF150F, and TBR7—offers a more focused model check than a generic universal listing. The material specification includes aluminum, stainless steel, and titanium, but does not identify which part uses each material. The supplied details do not establish additional fitments or installation hardware, so the named models and dimensions are the practical boundaries.

Skip it if you need a 28mm small-pit-bike muffler; GREHUA's 28mm exhaust lists 50cc through 125cc fitments.

This suits a HAWK 250, CRF230F, CRF150F, or TBR7 owner whose exhaust connection matches 38mm. Treat the named model list as its scope; the supplied details do not confirm broader dirt-bike compatibility.

8. ABCERRSI 28mm Muffler

• Compatible with Vehicle Type: ATV, Motorcycle, Scooter
• Material Type: Aluminum
• Outlet Connection Size: 28 millimeters

Best for: Low–mid-speed 28mm muffler.

Why it ranks #8: Its 28mm outlet and included adapter-ring support for 26mm or 30mm original interfaces offer sizing flexibility, but exact model fitment is not named.

A built-in porous baffle and spiral airflow channel distinguish this ABCERRSI muffler, with listed torque optimization for 3000–6000rpm and a 12% low-torque increase versus straight-through types. Its 28mm outlet and adapter-ring support for 26mm or 30mm interfaces add practical sizing information for off-road buyers.

The porous baffle and spiral airflow channel are specified as the basis for low- and medium-speed torque optimization, with the listing giving a 3000–6000rpm range and comparison against straight-through types. An adapter ring supports 26mm and 30mm original interfaces, while the outlet is listed at 28mm, helping buyers check connection options. Aluminum construction and the stated noise-reduction function suit an off-road muffler use case, though the supplied facts do not name particular bike models.

Skip it if you need named model compatibility; GREHUA lists CRF50, XR50, SSR110, and SSR125 fitments.

This is for riders prioritizing the listed low- and mid-speed characteristics and adapter-ring sizing on a 28mm-outlet muffler. Since no specific bike models are named, matching the original interface is essential.

9. LEIMO KPARTS Carbon Muffler

• Compatible with Vehicle Type: Bike,Motorcycle,Dirt Bike,Scooter,Atv,Scooters
• Material Type: Aluminum, Stainless Steel
• Inlet Connection Size: 1.5 in
• Outlet Connection Size: 5.1 centimeters

Best for: Versatile 38–51mm slip-on.

Why it ranks #9: This universal slip-on is listed for dirt bikes with pipe diameters from 38mm to 51mm and includes a removable DB killer.

A stated 38–51mm pipe-diameter range is the LEIMO KPARTS muffler's key differentiator, extending its listed use across dirt bikes, street bikes, scooters, and ATVs. The removable DB killer also lets riders choose between different sound effects, making it relevant to buyers prioritizing both connection flexibility and sound adjustment.

The 38–51mm compatibility range gives owners several pipe diameters to check against, while the listing describes use on dirt bikes, street bikes, scooters, and ATVs. Its aluminum and stainless-steel construction is specified as corrosion- and rust-resistant, supporting use across varied riding environments. The removable DB killer offers a sound-effect choice without replacing the muffler. Because this is a universal slip-on, the actual pipe diameter remains the key fit boundary rather than a named motorcycle model.

Skip it if you need a muffler with a named pit-bike fitment; GREHUA lists CRF50, XR50, SSR110, and SSR125 compatibility.

Choose this for a rider seeking a removable sound insert and a broad stated pipe-size range across bike types. It is less specific than a model-targeted part, so pipe diameter is the essential fit consideration.

#10

10. PACEWALKER Blue Slip-On Muffler

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

Best for: Blue-finish adjustable-sound slip-on.

Why it ranks #10: Its universal 38mm to 51mm inlet range and removable DB killer may suit some motorcycles, but the listing provides no specific dirt-bike model fitment.

The PACEWALKER combines a double-head baking-blue finish with a removable DB killer, pairing a visible gradient treatment with a choice of sound effect. Its stated 38–51mm inlet range targets riders looking for a universal motorcycle or scooter slip-on whose connection falls within that measurement window.

The titanium-alloy muffler and stainless-steel connector identify the main listed materials, while the baking-blue process is described as anti-rust and higher-strength. That finish gives the part a distinctive gradient appearance as well as its stated protective purpose. A removable DB killer allows different sound effects, and the 38–51mm inlet range supplies a practical dimension to check before installation. The listing describes motorcycle and scooter use but does not identify individual compatible models.

Skip it if you require both inlet and outlet dimensions before choosing; JFG RACING specifies 38mm for each connection.

This fits a motorcycle or scooter owner who wants the blue gradient finish and removable sound insert, provided the inlet measures within 38–51mm. The listing does not supply an outlet size or specific model fitment.
