Introducing the brand-new RS-4 Full 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 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.
The performance gains that were realized on this system are nothing short of amazing. The dyno tells us that this new RS-4 system gained 3 horsepower over the stock system plus increased torque throughout the entire RPM range.
It's time to change the exhaust on your KTM or Husky to Yoshimura
