The blue anodized titanium muffler with a carbon fiber end cap not only adds a sleek aesthetic but also provides superior heat resistance and longevity.

The Rapid Tuning System (RTS) allows for quick and easy adjustments to optimize the exhaust for different riding conditions, ensuring maximum efficiency. Manufactured entirely at FMF’s Southern California facility, this exhaust system meets rigorous quality standards and is designed to seamlessly fit your KTM model, providing a direct bolt-on upgrade that enhances both performance and aesthetics.
