FMF Racing Factory Fatty Big Bore 2-Stroke Exhaust Pipe

The FMF Racing Factory Fatty Big Bore is reminiscent of the “works” or cone pipe once used by Factory Teams. It shares many of the same characteristics with its’ craftsmanship and material quality. The Factory Fatty broadens and smooths out the power curve while boosting gains throughout the entire power band, more low end, more mid, and increased over-rev. No matter what type of riding you do, the Fatty has the benefits you’re looking for.
