DescriptionThis Yoshimura RS-4 exhaust 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 SX-F lineup.
This Full System comes with a titanium header and mid-pipe, titanium muffler sleeve, installation hardware, and detailed instructions.
Titanium Systems come with a AMA Pro Racing sound insert installed in the muffler.
