The FMF Factory 4.1 RCT Full Exhaust System is designed for high performance, featuring FMF's Resonance Chamber Technology (RCT) both internally and externally. It has a shorter overall length to reduce crash susceptibility and utilizes Factory Forward Engineering to centralize mass by positioning the muffler closer to the engine. Constructed from aerospace-grade materials, this system delivers significant power gains across the RPM range while providing substantial weight savings. The patented core and canister design enhance exhaust pressure, optimize sound absorption, and maintain maximum power output. The included Titanium MegaBomb header further improves performance. The system incorporates FMF's Rapid Tuning System (RTS) for easy adjustments and comes with a removable spark arrestor screen insert. The aluminum muffler features a carbon fiber end cap, combining durability with lightweight construction. Designed specifically for KTM 250SXF/XCF (2019-2022) and Husqvarna FC250/EX250F (2019-2023) models, this exhaust system offers a balance of power, durability, and advanced engineering.
