Description
As the official exhaust of the Yoshimura Suzuki Supercross/Motocross team, this exhaust 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.
This Full System comes with a Stainless steel header and mid-pipe, aluminum muffler sleeve, installation hardware, and step-by-step instructions.
An AMA-approved sound insert comes installed in the muffler, along with a 2 meter-Max insert in the box.
