Yoshimura has developed the current generation of RS-4 Slip-On Exhausts based on the research and development of winning multiple supercross and motocross titles, and the result is a unique design that provides an unrivaled combination of power and quiet exhaust tone. The RS-4 features a polyresonant duplex chamber and two-staged stepped baffle for increased performance, while a carbon cone end cap finishes off its innovative styling. This exhaust provides more punch at the bottom end without sacrificing the mid and top power while removing a good amount of weight from the stock unit and providing an exhaust note that is unmistakably Yoshimura and will have your heart revving for more!

In 1954, Hideo "Pops" Yoshimura, had a talent at modifying existing parts for more power, and started the Yoshimura™ company in Japan. Pops worked on planes, cars, and other combustion engine vehicles, but motorcycles were his specialty. In 1971 Pops added to Yoshimura™ by opening a shop in North Hollywood. Yoshimura Research and Development of America, Inc™ was born; manufacturing all sorts of equipment from exhausts, mufflers, and accessories to license plate frames and apparel. Products like Yosh RS-4 Signature Slip On AL Exhaust Pipe with "hands-on" building approach, rigorous work ethic, and race tested success that has grown the company exponentially.
