The work that went into developing the RS-4 muffler design has paid big dividends in Off-road Racing; winning multiple Supercross and Motocross titles since it's inception. Yoshimura developed the current generation RS-4 based on that R&D, and the result is a unique design that provides an unrivaled combination of power and a quiet exhaust note. The RS-4 features a Polyresonant duplex chamber, a two-staged stepped baffle, and an innovative carbon cone end cap.
