About this product
Unleash the full potential of your machine with the FMF Factory 4.1 RCT Exhaust System. This full system is engineered to deliver massive power gains across the entire RPM range while significantly reducing weight.
Description
The FMF Factory 4.1 RCT exhaust system features FMF's Resonance Chamber Technology™ both internally and externally. Its shorter overall length minimizes susceptibility to crash damage and complements FMF's Factory Forward Engineering by positioning the muffler closer to the engine, centralizing mass for improved handling. Constructed entirely from aerospace-grade materials to meet FMF's stringent standards, the Factory 4.1 RCT is manufactured in Southern California, ensuring top-tier quality and performance. The system includes the MegaBomb header for enhanced exhaust flow and the RTS (Rapid Tuning System) for easy adjustments, making it a top choice for riders seeking peak performance and tunability. With aluminum and stainless steel construction, and a carbon fiber end cap, this exhaust system is built to last and perform.
