The FMF Racing Fatty Gold Series pipe has set the standard in two-stroke exhaust design, combining over 35 years of racing development to deliver exceptional performance. Its carefully engineered profile broadens and evens out the power curve for smoother, more tractable power delivery, providing notable gains throughout the entire powerband—from enhanced low-end torque, right through to impressive top-end over-rev. Crafted from carbon steel and finished with a durable nickel plate, the Fatty is the go-to solution for riders seeking race-proven power improvements across all riding conditions. Features race-proven performance, refined over 35 years of development, smoothing and broadening the power curve for consistent output, and boosting power throughout the full RPM range. Enhanced traction and throttle control for superior rideability. Constructed from carbon steel with a robust nickel-plated finish. FMF Racing’s Tru-Flo stamping process ensures optimal fit and performance. Compatible with both FMF and original equipment silencers. Supplied complete with O-rings for straightforward installation. This is FMF Racing’s best-selling two-stroke expansion chamber. Item ID: 021048. Type: Pipes. Carb Warning: No. Weight: 3.4 lbs (approx. 1.54 kg).
