About this product
The FMF Factory 4.1 RCT exhaust system delivers top-tier performance and cutting-edge technology for your motorcycle. Designed for enthusiasts and professionals, this full system provides significant power gains and weight reduction.
Description
The Factory 4.1 RCT incorporates FMF's Resonance Chamber Technology™ both internally and externally, optimizing exhaust flow and maximizing power output. Its shorter overall length enhances durability by reducing susceptibility to crash damage and supports FMF's Factory Forward Engineering, which centralizes mass by positioning the muffler closer to the engine. Constructed entirely from aerospace-grade materials to meet stringent specifications, the Factory 4.1 RCT is 100% manufactured in FMF's Southern California facility, ensuring exceptional quality and performance. The stainless steel collector provides enhanced durability and corrosion resistance, while the aluminum muffler offers a lightweight design. The black carbon fiber end cap adds a stylish and high-performance touch.
