Features of the Yoshimura RS-4 Exhaust:
The Yoshimura RS-4 exhaust system was designed with one thing in mind, winning races. The RS-4 is a unique design with predicated power, and a quiet earthy exhaust note that speaks volumes for performance. It was an obvious choice for the 350 SX-F.
Comp Series Slip-Ons include an RS4 muffler, stainless steel tail pipe, USFS approved spark arrester, all necessary hardware, and detailed installation instructions to get you moving.
