FMF Racing Yamaha YZ450F 14-17/ WR/YZ450FX 16-18 Anod TI Factory 4.1 RCT SO Muffler w/R. Carbon Cap

What you get with this FMF Racing Factory 4.1 RCT SO Muffler is a well-built exhaust component designed to improve your Yamaha's performance. This muffler features a blue anodized titanium body and a carbon fiber end cap, giving it a distinct look. It's built using aerospace-grade titanium alloys that meet FMF's strict standards, and it's manufactured entirely at their Southern California factory.

The Factory 4.1 RCT design incorporates FMF's Resonance Chamber Technology, both internally and externally, to help manage sound and exhaust flow. Its shorter overall length is a practical advantage, making it less likely to sustain damage from impacts and allowing for better mass centralization by moving the muffler closer to the motor. This design contributes to significant power gains across the entire RPM range, and the included Rapid Tuning System (RTS) allows for adjustments to fine-tune performance.

This muffler is a solid option for riders looking to extract more power from their Yamaha WR250F, YZ250F, or YZ250FX. Its robust construction and thoughtful design aim to provide both improved performance and increased durability for your off-road adventures.
