Description

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 YZ450F.

This Full System comes with a Titanium header and tail-pipe, Titanium 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.
