Factory Fatty Exhaust Pipe 05-07 Honda CR 250 R - FMF 021055

The FMF Racing Factory Fatty 021055 exhaust pipe is engineered for riders who demand factory-level performance and craftsmanship. Drawing inspiration from the renowned “works” or cone pipes once reserved for factory teams, this exhaust utilises high-grade materials and meticulous hand-finished seams to optimise exhaust flow. The Factory Fatty delivers a broader, smoother power curve with significant gains in low-end torque, midrange response, and top-end over-rev, providing exceptional throttle performance for varied riding conditions.
