Factory Fatty Exhaust Pipe 19-23 KTM Husqvarna GasGas 250 300 - FMF 025243

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.
