About this product
Unleash the full potential of your machine with the FMF Factory 4.1 RCT Exhaust System. Engineered for maximum performance and durability, this exhaust system will transform your riding experience.
Description
The FMF Factory 4.1 RCT exhaust system utilizes Resonance Chamber Technology™ both internally and externally, delivering significant power gains throughout the entire RPM range. Its shorter overall length reduces the risk of damage during crashes and complements FMF's Factory Forward Engineering, which centralizes mass by positioning the muffler closer to the engine. Constructed entirely from aerospace-grade materials to FMF's stringent standards, the Factory 4.1 RCT is manufactured in Southern California, ensuring top-tier quality and performance. The included MegaBomb header enhances exhaust flow and boosts power, while the RTS (Rapid Tuning System) allows for quick and easy adjustments. Experience a massive improvement in power and a significant reduction in weight, all in one high-performance package.
