Description
The FMF Racing Factory 4.1 RCT Slip-On Exhaust is designed for maximum performance, featuring a blue anodized titanium muffler with a carbon fiber end cap. Constructed from a proprietary blend of alloy-grade titanium, it offers significant weight savings and increased durability. This slip-on exhaust system incorporates the latest resonance chamber technology, optimizing exhaust pressure for enhanced power delivery throughout the RPM range. Its patented core shape reduces sound levels while maintaining peak performance, and the canister design increases internal volume for improved sound absorption. Additional features include the Rapid Tuning System (RTS) for easy adjustments, a titanium mid-pipe for further weight reduction, and a factory-forward engineering design that centralizes mass, making it less prone to crash damage. The innovative rear endcap allows for effortless installation of tuning tip inserts or a spark arrestor.
