About this product
Unleash the ultimate performance from your machine with the FMF Factory 4.1 RCT Exhaust System. Engineered for demanding riders, this system delivers unparalleled power, reduced weight, and a distinctive exhaust note.
Description
The FMF Factory 4.1 RCT exhaust system utilizes FMF's Resonance Chamber Technology™ (RCT) internally and externally, optimizing exhaust flow and maximizing power delivery. Its shorter overall length minimizes vulnerability to crash damage and complements Factory Forward Engineering, which centralizes mass by positioning the muffler closer to the engine. Crafted entirely in FMF's Southern California factory from aerospace-grade materials, the Factory 4.1 RCT meets the most stringent specifications. The stainless steel piping ensures durability and resistance to corrosion, while the aluminum muffler delivers a lightweight design. The system's conical end cap is made of carbon fiber and has a black finish for a sleek look. The anodized gray muffler also adds to the aesthetics of the exhaust system. Experience the difference that precision engineering and premium materials make on the track or trail with the FMF Factory 4.1 RCT exhaust.
