Product Details

FMF Racing is well-known for making high-performance exhaust systems for off-road motorcycles. This Factory 4.1 RCT muffler is built for your 2019-2022 Yamaha YZ250F or 2020-2021 YZ250FX, and it's designed to give you a significant boost in power across the entire RPM range. It uses FMF's latest Resonance Chamber Technology, both inside and out, to help the engine breathe better and make more power.

This muffler is constructed from aerospace-grade titanium, which is strong and lightweight. It features a blue anodized finish on the titanium body and a carbon fiber end cap, giving it a sharp look. The design is also shorter than stock, which helps to move the muffler closer to the motor. This centralization of mass can improve the bike's handling, and the shorter length also makes it less likely to be damaged in a crash. The Rapid Tuning System (RTS) allows for quick adjustments, and the entire muffler is manufactured at FMF's Southern California factory, meeting their strict specifications.

When installing this muffler, you'll want to ensure all connections are sealed properly to get the most out of the power gains and sound. It's a direct replacement for your stock muffler, designed to fit right onto your Yamaha YZ250F or YZ250FX.
