DescriptionThe 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 SX-F lineup.
Slip-On includes RS-4 muffler, stainless steel tail-pipe, installation hardware, and detailed instructions to get you moving! An AMA-approved sound insert comes installed in the muffler, along with a 2 meter-Max insert in the box.
