DescriptionAs the official exhaust of the Yoshimura Suzuki
Supercross/Motocross Team, this muffler was designed with one thing in mind,
winning races. The RS-4 is a unique design with predicated power, a side benefit of a quiet earthy exhaust note that speaks volumes for performance. It was an obvious choice for the RM-Z450.
This Slip-On comes with a stainless steel tail-pipe, aluminum muffler sleeve, 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.
