About this product
The FMF Factory 4.1 RCT Exhaust System delivers unparalleled performance and durability for closed course competition. Experience the pinnacle of exhaust technology with aerospace-grade materials and innovative design, all meticulously crafted in FMF's Southern California factory. This exhaust system is engineered to enhance your motorcycle's power and responsiveness, providing a competitive edge on the track.
Description
This Factory 4.1 RCT exhaust incorporates FMF's Resonance Chamber Technology™ both internally and externally, optimizing exhaust flow and maximizing power output. Its shorter overall length minimizes vulnerability to crash damage while complementing Factory Forward Engineering, which centralizes mass by positioning the muffler closer to the motor. Constructed from aerospace-grade materials to exacting specifications, the system ensures exceptional durability and performance. The stainless steel pipe combined with the aluminum muffler delivers the ideal balance of strength and weight savings. The black carbon fiber end cap adds a touch of style to its high-performance design. Designed for race applications and will not pass 2025 FIM sound regulation.
