EOPOAYI 28mm Slip-On Muffler for 110–125cc Pit Bikes — Lightweight Corrosion-Resistant

EOPOAYI 28mm slip-on muffler is a lightweight, corrosion-resistant replacement silencer designed to fit many 110cc–125cc pit bikes, ATVs, mini bikes and small engines.

This muffler is built to be a direct-replacement slip-on that pairs with a wide range of Chinese 4-stroke pit bikes, go-karts, and small OHV engines. It ships with a clamp and screw kit plus a long heat-shield wrap so you can install it quickly and protect nearby components from heat. The 28mm (1.1 inch) inlet and compact profile make it suitable for machines where space and weight matter.

Will this muffler fit my 125cc or 110cc pit bike?

Compatibility covers many common Chinese 4-stroke pit bikes and ATVs; the muffler is sized for a 28mm inlet so it slips onto 110cc–125cc exhaust outlets and similar small-engine pipes. Confirm your exhaust outlet measures roughly 28mm (1.1 inch) before ordering to ensure a snug fit.

• Fits many CRF50, SSR, Apollo, TTR-style pit bikes as listed by manufacturers
• Compatible with most 50cc–140cc Chinese 4-stroke models and some ATVs
• Works with small OHV engines and utility equipment that accept a 28mm slip-on

How easy is installation and what hardware comes with it?

Installation is straightforward: the muffler slips onto the exhaust pipe and secures with the included metal clip and screws. A 1.5 m heat-shield wrap is provided so you can fully cover the pipe for safer operation and reduced heat transfer.

• Includes clamp and screw kit for a firm attachment
• 1.5 m heat-wrap to protect frame and rider from hot pipe
• Lightweight design simplifies mounting and handling

What materials and durability can I expect from this exhaust?

The muffler is manufactured from a high-quality metal alloy that balances weight and strength. It’s designed to resist scratches and corrosion in typical off-road or utility use, giving reliable service when mounted correctly and maintained.

• Corrosion-resistant metal construction for longer service life
• Finished for scratch resistance under normal use
• Compact, hardened design suited to off-road vibration and heat

Can this muffler be used on go-karts, generators or non-bike engines?

Yes—its 28mm slip-on design makes it compatible with a variety of small engines beyond pit bikes, including many mini bikes, go-karts, and small OHV power units. Check the engine or exhaust pipe diameter and mounting layout to ensure fitment.

• Works with many mini bike and go-kart models such as Coleman CT200 series and Baja MB series
• Compatible with numerous small OHV clones and popular engine sizes (e.g., 79cc–212cc variations)
• Ideal for replacements where the original exhaust is damaged or noisy

Who is this for: Riders, hobbyists, and small-engine users who need a compact, affordable replacement muffler for 110cc–125cc pit bikes, ATVs, mini bikes, go-karts, or similar small engines. It’s targeted at people who want an easy-to-install slip-on silencer with a heat shield and basic hardware included, not a full-performance aftermarket header.
