FMF Fatty Gold Series Expansion Chamber (21052)

THE FATTY GOLD SERIES pipe is the cornerstone of FMFs 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 FMFs heritage and dedication to performance.
