FMF Racing Yamaha YZ250F 10-13 SS Alum Factory 4.1 RCT SO Muffler w/ R. Carbon Cap

FMF Racing is well-known for building high-performance exhaust systems for off-road motorcycles. This Factory 4.1 RCT muffler is designed specifically for your 2010-2013 Yamaha YZ250F, aiming to give you a significant boost in power across the entire RPM range. It's built to be less prone to damage from impacts, thanks to its shorter design, and it also helps centralize the bike's mass by moving the muffler closer to the engine.

This muffler is constructed using only aerospace-grade titanium, meeting FMF's strict standards. The titanium body features a blue anodized finish, and it's capped off with a carbon fiber end cap. Inside, it incorporates FMF's latest Resonance Chamber Technology, both externally and internally, to help tune the exhaust flow for improved performance. The Rapid Tuning System (RTS) is also part of its design, allowing for adjustments to optimize the exhaust characteristics.

Everything on this muffler is manufactured 100% at their Southern California factory, ensuring close attention to detail. This is a well-built component designed to make a noticeable difference in your YZ250F's performance.
