Description
* Carbon Fiber muffler sleeve shown for display purposes.
As the official exhaust of the Yoshimura Suzuki Supercross/Motocross
Team, this system 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 Full System comes with a titanium header and mid-pipe, carbon muffler sleeve, installation hardware, and detailed
instructions to get you moving!
Titanium Systems come with a AMA Pro Racing sound insert installed in the muffler.
