Product Information
The FMF Racing Factory Fatty Exhaust Pipe for the 2025 Fantic XE300 is engineered for riders who demand performance and precision. Modeled after the original works-style cone pipes, the Factory Fatty delivers a broader, smoother powerband with measurable gains in low-end torque, midrange responsiveness, and top-end over-rev.
This pipe features a lighter 20-gauge steel body and a 19-gauge steel header, combined with hand-formed seams to ensure smooth flow transitions and consistent build quality. It’s designed to improve performance across all riding conditions, whether you're trail riding, racing, or pushing through technical terrain.
A set of high-quality O-rings is included for most models to ensure a proper seal during installation.
