Increase performance across the power range with the FMF Fatty Pipe, manufacturer part number 020137. Designed for Yamaha two-stroke riders seeking stronger, more usable power, this exhaust pipe helps deliver responsive performance from low through high RPM. The Fatty model is an all-around choice for trail riding, motocross, and off-road use where broad power delivery is preferred.
Feature: Electro-nickel-plated finish provides a durable, non-chip surface that resists discoloration during normal use. The coating is applied to FMF aftermarket pipes for long-lasting appearance and protection, while maintaining the fit and performance expected from a performance expansion chamber.
Feature: Broad power increase improves engine response throughout the usable powerband, making the FMF Fatty a versatile upgrade for riders who want stronger acceleration without focusing exclusively on low-end torque or peak top-end output. The pipe is designed to complement Yamaha's two-stroke engine characteristics and is suitable for varied riding conditions.
Fitment includes 1994–1997 Yamaha WR250 and 1993–1997 Yamaha YZ250 models. Verify the motorcycle model year and existing exhaust configuration before installation.
