FMF Racing Honda CRF450X / RX 21-24 SS Aluminum Factory 4.1 RCT Complete System w/ TI MB Header

FMF Racing is well-known for making high-performance exhaust systems for off-road motorcycles. This Factory 4.1 RCT complete system is built for your 2021-2023 Honda CRF450R, CRF450RX, or 2021 Kawasaki KX250F. It's designed to give you a significant boost in power across the entire RPM range, making your bike more responsive and potent.

This system uses FMF's latest Resonance Chamber Technology, both inside and out, to help tune the exhaust flow. The muffler itself is shorter, which not only helps reduce damage from impacts but also moves the muffler closer to the engine. This centralization of mass can improve the bike's handling. The entire system is constructed from aerospace-grade materials, meeting FMF's strict standards, and is manufactured entirely at their Southern California facility. The muffler features a blue anodized titanium finish with a carbon fiber end cap, and it includes a titanium mid-pipe header.

The Rapid Tuning System (RTS) allows for adjustments to optimize performance. This is a complete system, meaning it replaces your stock exhaust from the header back, offering a comprehensive upgrade for your bike's performance and sound.
