The FMF Racing Factory 4.1 RCT exhaust system is engineered for high-performance KTM models including the 350XCF-W from 2020 to 2022, FE350 from 2020 to 2022, and EC350F from 2021. Crafted with aerospace-grade titanium, this system offers exceptional durability and weight savings, ensuring optimal power delivery and responsiveness across the entire RPM range. The inclusion of FMF's proprietary Resonance Chamber Technology™ enhances exhaust flow, resulting in increased horsepower and torque while maintaining a sleek, lightweight profile. The anodized blue titanium muffler, complemented by a carbon fiber end cap, provides a striking aesthetic that resists corrosion and heat damage. Its shorter overall length improves crash resistance and allows for more precise handling, especially in aggressive riding conditions. The Factory 4.1 RCT integrates seamlessly with FMF’s Rapid Tuning System (RTS), enabling quick adjustments to optimize performance based on riding terrain and personal preferences. Designed and manufactured entirely in Southern California, this exhaust system adheres to strict quality standards, ensuring long-lasting performance and reliability for serious riders seeking to maximize their motorcycle’s capabilities.
