About this product
Unleash the full potential of your machine with the FMF Factory 4.1 RCT Exhaust System. Engineered for enthusiasts and professionals alike, this full system delivers unparalleled performance and durability.
Description
The FMF Factory 4.1 RCT exhaust system is a game-changer in exhaust technology, incorporating FMF's advanced Resonance Chamber Technology™ (RCT) both internally and externally. This innovative design ensures massive power gains throughout the entire RPM range. The shorter overall length not only reduces the risk of damage from crashes but also complements FMF's Factory Forward Engineering, which strategically positions the muffler closer to the motor for optimal mass centralization. Constructed entirely from aerospace-grade materials at FMF's Southern California factory, the Factory 4.1 RCT meets the highest standards of quality and performance. Experience the difference with improved throttle response, increased horsepower, and significant weight savings, all thanks to the Factory 4.1 RCT. The system also features the new RTS (Rapid Tuning System) for quick and easy adjustments.
