Yoshimura 264612D322 Signature RS-4 Slip-on Exhaust KTM & Husqvarna Models

Yoshimura’s 264612D322 Signature RS-4 Slip-on Exhaust, SS-AL-CF(Stainless Steel, Aluminum, Carbon Fiber) is made specifically for KTM 450SX-F / 500EXC-F / Husqvarna FC450 / FX450 (2016-current).

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.
