FVRITO Exhaust Muffler Kit 28mm for 70-125cc Pit & Dirt Bikes — Red, Double-Layer Stainless

FVRITO’s one-piece 28mm exhaust muffler kit is a complete head-pipe-to-tail assembly that gives 70cc–125cc pit and dirt bikes a deeper, fuller sound while improving exhaust flow for modified and stock engines.

This full exhaust system ships as a ready-to-install kit for many Chinese-made mini dirt bikes and Honda CRF50/XR50-style copies. Constructed with double-layer stainless internals and a removable 28mm pipe guard, the assembly is engineered to suppress vibration, manage resonance and deliver a stronger tone without replacing multiple parts. The package includes the muffler, head pipe, gaskets, clip and screw kit so you get a complete swap in one purchase.

How will this exhaust affect my bike’s sound and throttle feel?

The FVRITO muffler is designed to produce a deeper, more resonant exhaust note similar to larger CRF-style bikes, accentuating low-end bark while keeping harsh frequencies under control. Riders often notice a punchier, freer-revving feel when the engine breathes with less restriction. It’s balanced to improve acoustic presence without excessive drone at cruising speeds.

• Deeper, resonant tone for a more aggressive sound
• Double-layer stainless internals reduce vibration and harshness
• Improved exhaust flow can help throttle response after simple modifications

Will this kit fit my pit bike and what are the exact dimensions?

The kit fits many 70cc–125cc mini/dirt bikes, including Honda CRF50/XR50-style models and a wide range of Chinese brands such as SSR, Thumpstar, Apollo, Taotao, Coolster and others. The removable pipe guard and head diameter measure 28mm, and the eye-to-eye distance is approximately 45mm. Always verify measurements against your bike’s manifold and mounting points before purchase.

• Head diameter: 28 mm
• Removable pipe guard: 28 mm
• Eye-to-eye distance: 45 mm (approximate, hand-measured)
• Compatibility: CRF50/XR50 copies and many 70–125cc Chinese models

What’s included and how easy is installation?

The exhaust kit arrives with all necessary hardware for a straightforward swap: muffler, head pipe, metal clip, rubber gasket, two additional gaskets and a screw kit. Installation typically involves removing the old system, aligning the head pipe to the manifold, fitting gaskets and securing mounts—common maintenance skills for pit bike owners. If you’re unsure, a local shop can complete the job quickly.

• Complete kit: muffler, head pipe, clip, rubber gasket, two gaskets, screw kit
• One-piece system reduces alignment steps compared to multi-piece setups
• Basic tools and mechanical familiarity required; shop install recommended if inexperienced

Does the exhaust affect durability and vibration?

FVRITO’s muffler uses double-layer stainless steel construction on the inner walls to increase longevity and improve vibration damping. The thicker internal layers help resist corrosion and contain resonant frequencies that would otherwise transmit through the frame. This results in a more solid-feeling assembly under acceleration and longer service life than thin single-layer designs.

• Double-layer stainless internals for added strength
• Designed to absorb vibration and reduce metal fatigue
• Robust build suited for off-road conditions

Who is this for: This FVRITO exhaust kit is aimed at pit bike and mini dirt bike riders who want a fuller, deeper exhaust note and improved flow without a multi-piece installation. It’s a good match for owners of 70cc–125cc Chinese-made bikes and CRF50/XR50-style models looking for a durable, ready-to-fit upgrade. Confirm your bike’s head diameter and mounting points before ordering, and consider professional installation if you’re not comfortable with basic exhaust work.
