About this product
About this product
The FMF Factory 4.1 RCT exhaust system is engineered for superior performance and durability in closed course competition. This system utilizes advanced technology and high-quality materials to deliver maximum power and reduce the risk of damage.
Description
The Factory 4.1 RCT incorporates FMF's Resonance Chamber Technology™ both internally and externally, optimizing exhaust flow and increasing power across the RPM range. Its shorter overall length minimizes vulnerability to crash damage and complements Factory Forward Engineering, positioning the muffler closer to the engine for improved mass centralization. Crafted entirely from aerospace-grade materials to exacting standards and manufactured in FMF's Southern California facility, this race exhaust system delivers unparalleled quality and performance. Note that this system is designed exclusively for closed course competition and will not meet the 2025 FIM sound regulation.
