FMF Gnarly Pipe

The FMF Gnarly Pipe is a 2-stroke expansion chamber exhaust pipe built for dirt bikes and off-road motorcycles. It is designed to tune exhaust pulses for better engine performance, so riders can get stronger, more usable power from their 2-stroke engine. Racers and trail riders also call it an expansion chamber, 2-stroke exhaust pipe, or exhaust header pipe.

Key Features:

• Expansion chamber design that is tuned to improve 2-stroke power delivery
• Designed for off-road, motocross and enduro use
• Built to take the vibration and impacts of hard riding
• Made by FMF Racing, a well-known name in motorcycle exhaust
• Made to pair with an FMF silencer or a compatible spark-arrestor-equipped silencer

The Gnarly Pipe line gives 2-stroke riders a proven way to get more out of their engine. Check each individual listing for the specifications that apply to that part number.
