Yoshimura Street Series RS-4 Mufflers

Not Yet Reviewed

Yoshimura Street Series RS-4 mufflers deliver more power and fewer decibels. These light exhausts feature a carbon fiber cone end-cap, a 2-stage stepped baffle, and striking good looks. Their front cap design functions as a poly-resonant chamber, making for quieter mufflers with improved mid to top-end power. Material options of stainless steel and carbon fiber are available for the muffler body. Yoshimura's Street Series offers street-legal options for almost everything on two wheels.
