FMF Factory 4.1 RCT Slip-On Muffler is a high-end exhaust upgrade designed for riders who want maximum performance, premium materials, and a smarter fitment that’s better protected in real riding conditions. By incorporating FMF Resonance Chamber Technology™ (RCT) both internally and externally, it’s engineered to deliver strong power characteristics while maintaining a refined factory-level build quality.
Its shorter overall length helps reduce the chance of crash damage and supports mass centralization by positioning the muffler closer to the engine—an advantage for handling and agility on track or trail.
