Constructed from thick 18 gauge steel, the Gnarly was made specifically for those who ride in the roughest terrain and require the strongest, most reliable equipment. The performance of the Gnarly is focused toward a strong low end with meaty midrange to provide the torque and tractability of a 4-stroke but still maintain the responsiveness of a 2-stroke. The Gnarly is the preferred pipe for our top Enduro and GNCC riders where abrupt power and rugged durability are a must.
The SST is our premier 2-stroke pipe. The exclusive SST module provides huge power increases throughout the RPM range. Off idle throttle response is immediate and the powerband becomes broader through the midrange. The SST continues pulling hard into the upper RPM range where other pipes sign off. Anything else feels anemic in comparison.

FATTY
The Fatty Gold Series pipe is the cornerstone of FMF’s history. With over 35 years of racing experience behind it, the FMF Fatty is the industry benchmark. Our philosophy is simple - give you more power. More at the crack of the throttle, more in the meaty part of the powerband and more over the top. FMF was also the first to introduce a nickel plated finish that would not rust. The Fatty is a symbol of FMF’s heritage and dedication to performance.
The Factory Fatty was once only available to Factory Race Teams. This pipe is based on the world famous Fatty but constructed from a thinner gauge metal with hand pounded seams – materials and techniques that make a true “Works” pipe.
The Factory Fatty is renowned for its thick and linear powerband - always with power on demand.
Hand pounded seams for superior flow
Lighter gauge metal for the Factory sound
Broader, smoother powerband
More tractable power, better throttle control
Unplated 20 gauge header and 19 gauge body for a true Factory pipe
