FMF Gnarly Pipe is a heavy-duty 2-stroke head pipe designed to increase low-RPM horsepower and torque for getting through tough off-road terrain. Built for riders who want stronger bottom-to-mid pull with a rugged pipe that can take abuse.
FMF Gnarly Pipe is built for riders who demand more usable power where it matters most—down low—when the trail gets technical and traction is limited. Its purpose is simple: add that “4-stroke tractor-like” torque feel to your 2-stroke so you can pull harder out of corners, lug through obstacles, and climb out of the toughest terrain with less clutch work.
Designed to withstand harsh off-road conditions, the Gnarly is a strong, aggressive pipe that delivers the bottom-to-mid range pull many late-model 200cc to 500cc machines need for enduro and off-road riding.
Note: This pipe will not pass 2025 FIM sound regulation.
