Authorized Yoshimura dealer

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. 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. They took everything learned over the last several years with their world famous RS-4 muffler and revised it with the latest materials and an updated spec that makes this new model perform.
