Introducing the brand-new RS-4 Slip-On system from Yoshimura R & D of America. Yoshimura took the time to develop and test in order to deliver the best exhaust system available for the new RM-Z450, 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 Suzuki to Yoshimura.
