Yoshimura Signature Series RS-4 Mufflers

Yoshimura Signature Series RS-4 mufflers deliver more power and fewer dB, with an improved sound for the rider who values quality over volume. These light off-road mufflers feature a carbon fiber cone end-cap, a 2-stage stepped perforated baffle, and noticeable good looks. And their front cap design functions as a poly-resonant chamber, making for quieter exhaust notes with improved mid- to top-end power. USFS-approved spark arrester sound inserts come installed in the mufflers. Material options of polished aluminum and stainless steel are available for the mufflers. Yoshimura Signature Series RS-4 components are tested, documented, and marked as required by federal and state regulations. Order the model recommended for your application. Show Less
