FMF 4.1 RCT Stainless Steel Slip-On 2011 KTM 250/350/450 SX-F

This has been a work in progress for over 1 year and FMF has learned a lot over the last few years of racing with the RCT (Resonance Chamber Technology) with many of our factory race teams. The goal with the new exhaust was to offer a new design that really fits the complex lines that many of the new manufactures are leaning towards. We are very excited for you to see some of the new features including a bigger volume can which can utilize more packing for better performance and longer lasting low output sound volume. The new insert clip feature is another breakthrough in exhaust manufacturing and the detail really shows when looking at the rear insert. As mentioned before the new RCT in the front end of the exhaust is another huge added gain for sound and performance, which we have utilized from working feverishly on lowering sound outputs. This exhaust is sound compliant with the FIM 2M Max sound test, which as you know is a lot more of a spot on test. With that said, we are excited for you to test the new product from FMF Racing.
