    Yosh’s RS-4 Slip-on is a staple in their race-tested lineup that maximizes weight savings and power to give you the ride of your life. The RS-4 is set apart by its pentagonal muffler shape that is done specifically to maximize internal volume without making the entire slip-on unwieldy in size. The front cap of the RS-4 is a newly designed polyresonant chamber that works along with the stepped, two-stage core baffle to lower sound and bump up power output in the mid to top end of your power band. Yoshimura has designed the RS-4 for good looks too with the stainless steel and aluminum giving the slip-on a clean look and the carbon end cap bringing the attitude. It’s more than skin deep though as the RS-4 is built to last seasons of hard riding. It connects to the header pipe using a robust clamp, not just gasket maker, and secures to the bike using a mounting tab that is welded to the muffler instead of riveted for long lasting durability.

    With a twist of your wrist you can find out how much of a difference the Yoshimura RS-4 will make to your bike ’s performance. Get some new gloves, because you’ll need to hold on tight.
