The FMF Racing Factory Fatty 025243 exhaust delivers high-performance
gains by utilising the iconic hand-crafted “works” or cone pipe
approach, previously favoured by factory race teams. Designed to widen
and smoothen the power curve, this pipe increases low-end
responsiveness, boosts mid-range torque, and enhances over-rev
performance. Constructed from premium materials for optimal
strength-to-weight, the Factory Fatty ensures enduring reliability and
enhanced ride quality across diverse off-road and competition
environments.

Features

Hand-pounded seams optimise exhaust flow for smoother transitions
Constructed from lightweight 20-gauge steel in the body for improved
weight savings
Durable 19-gauge steel header increases longevity where exposed to heat
and impacts
O-rings included on most models for precise and leak-free installation
Broadens the power curve for balanced performance at all RPMs
Delivers consistent gains across low, mid, and high ranges
High-level craftsmanship reminiscent of elite factory racing equipment
