FVRITO 49cc 2-Stroke Exhaust Silencer for 80cc Motorized Bicycle — 945mm Flexible Stainless Expansion, Reinforced Flange

FVRITO’s 49cc 2-stroke exhaust silencer is a replacement muffler and flexible expansion pipe designed to fit 49–100cc 2-stroke small engines for motorized bicycles, pocket bikes, scooters and pit bikes.

This compact performance silencer pairs a bendable stainless-steel expansion section with a reinforced flange to reduce noise, improve fitment options and resist warping during installation. It’s engineered as an adaptable aftermarket muffler that can be mounted at multiple angles, comes with a full mounting gasket and nut kit, and measures 945mm total length with 40mm flange hole spacing. Use this when you need a durable, quieter alternative to a worn or noisy stock exhaust on a variety of 2-stroke engines.

Will this FVRITO muffler fit my engine and bike?

The FVRITO silencer is built for broad compatibility across small 2-stroke engines. It fits 49cc and 50cc setups and is also compatible with many 60cc, 66cc, 80cc and 100cc motorized bicycle and pocket bike engines that accept a similar flange spacing and outlet geometry.

• Compatible engine range: 49cc–100cc 2-stroke small engines
• Common vehicle types: motorized bicycles, pocket bikes, scooters, pit/dirt bikes
• Mounting hole distance: 40mm (1.57 in)
• Total length: 945mm (37.2 in) — check clearance and routing

How does the muffler attach and adapt to different engine positions?

The design includes a reinforced flange and a flexible stainless-steel expansion pipe that allow varied mounting angles and help prevent exhaust leakage. The weld reinforcement beneath the flange reduces the chance of warping from over-tightening so you get a more reliable seal.

• Reinforced mounting flange to resist deformation
• Flexible stainless section for angled routing and tight fits
• Comes with gasket and nut kit for installation
• Replacement-friendly form factor for common small-engine layouts

What noise and longevity improvements can I expect?

This aftermarket silencer is designed to be quieter than many stock units while remaining durable for long-term use. The internal silencing and the expansion pipe geometry reduce harsh exhaust tone and provide a steadier sound profile under load.

• Quieter operation than many original mufflers
• Durable materials for extended service life
• Reinforced welds to prevent leaks and premature failure
• Suitable for repeated installations and adjustments

What comes in the box and what should I check before buying?

The package includes one muffler exhaust pipe and a full mounting gasket/nut kit so you have the essentials for a straightforward swap. Before purchasing, compare your engine’s flange hole spacing, available routing length and mounting clearance to the muffler’s dimensions.

• Included: 1x muffler exhaust pipe, 1 set mounting gasket and nut kit
• Key dimensions: 945mm total length, 40mm mounting hole distance
• Pre-purchase check: flange compatibility, exhaust outlet diameter, routing clearance
• Installation tip: test-fit routing before final tightening to avoid flange stress

Who is this for? The FVRITO 49cc 2-stroke exhaust silencer is aimed at riders and DIY mechanics who need a robust, flexible replacement for worn-out or noisy stock mufflers on 49–100cc 2-stroke small engines. It suits owners of motorized bicycles, minibikes, scooters and pit bikes seeking easier fitment, reduced noise and a longer-lasting mounting solution, provided the vehicle’s flange spacing and piping route match the silencer’s measurements.
