Description
Yoshimura has developed the current generation of RS-4 Full System 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!
