Yoshimura - RS-4S Slip-On (Yamaha)

The RS-4 is a unique design with predicated power and a quiet earthy exhaust note that speaks volumes for performance. The RS-4S features all the benefits of our original RS-4 muffler, but with a unique feature in the end-cap. The RS-4S has a turned-out end-cap, designed to direct exhaust heat and gases away from the bike's components. With all its benefits in mind, the RS-4S was an obvious choice for the WR450F.

Slip-On includes an RS-4S muffler, stainless steel tail-pipe, USFS approved spark arrester, all installation hardware, and step-by-step instructions.
