FVRITO 28mm Exhaust Muffler Kit for 70–125cc Pit & Dirt Bikes, Black — Stainless Steel Double-Layer Complete System

The FVRITO Exhaust Pipe Muffler Silencer Kit is a complete 28mm exhaust system designed to replace worn factory pipes on 70cc, 110cc and 125cc pit and dirt bikes, improving durability and producing a deeper, more resonant sound.

If your small-displacement pit bike needs a sturdier exhaust with better tone and reliable fitment, this integrated system from FVRITO offers an easy swap. It includes the muffler, head pipe, mounting hardware and gaskets so you can install a single unit from manifold to tailpipe. The kit’s double-layer stainless steel inner walls are built to resist vibration and prolong service life while tuning the exhaust note for a richer roar.

Will this muffler fit my 70cc–125cc pit bike?

What sound and performance changes should I expect?

The FVRITO muffler is tuned to produce a deeper, fuller exhaust note compared with stock silencers. While primarily intended to enhance tone and durability, the design can also improve exhaust flow characteristics, which may influence throttle response on small-displacement engines.

• Resonance-focused design to enrich sound without extreme volume spikes.
• Includes gaskets and mounting hardware to maintain a reliable seal.

What comes in the box and how hard is installation?

The kit ships complete with the parts needed for a standard replacement and is intended for owners comfortable with basic bike maintenance. You’ll receive the muffler, head pipe and a screw kit; a simple set of hand tools is usually sufficient for installation.

• Package: exhaust muffler, exhaust head pipe, metal clip, rubber gasket, two additional gaskets, and screw kit.

• Service tip: inspect the manifold flange and replace any worn studs or seals for the best fit.
