Questions & Answers

Ask Question

Does it require rejetting

While it's not required, we highly recommend that you rejet your machine so as to get the best possible throttle response and engine power output. FMF even makes a jet kit that's perfectly matched to go along with their exhausts in the form of the FMF Power Up Jet Kit. With that, you'll get everything you need and the included instructions do an excellent job of explaining how to tune your bike for maximum benefit.
