Description
The Yoshimura RS-4 exhaust system was designed with one thing in mind,
winning races! The RS-4 is a unique design with predicated power and a
quiet earthy exhaust note that speaks volumes for performance. It was an
obvious choice for the SX-F Factory Edition.
Full System
includes an RS-4 muffler, titanium header and tail-pipe, all necessary hardware, and detailed installation
instructions.
Titanium Systems come with a AMA Pro Racing sound insert installed in the muffler.
