Yoshimura took the time to develop and test in order to deliver the best exhaust system available for the new KTM and Husqvarna 450, and the results were worth the wait. We took everything we have learned over the last several years with our world famous RS-4 muffler and revised it with the latest materials and an updated spec that makes this new model perform.
It's time to change the exhaust on your KTM or Husky to Yoshimura.
NOTE: *500EXC-F stock turn signals must be relocated as the muffler outlet is in the direct line of the turn signal.
