Product Description

The FMF Factory Fatty Pipe is reminiscent of the works or cone pipe once used by factory racing teams, sharing the exact same characteristics in craftsmanship and material quality. It broadens and smooths out the power curve while boosting power gains across the entire power band, delivering enhanced low-end, stronger mid-range pull, and increased over-rev.

Constructed using a lighter 20-gauge steel body and a robust 19-gauge steel header portion, this expansion chamber features hand-pounded seams to ensure smooth flow transitions. Whether you ride trials, cross-country, or enduro trails, the Fatty provides the performance advantages you need.
