Yoshimura - RS-4 Exhaust System (Yamaha)
Yoshimura R&D has developed an evolutionary new exhaust system. The all-new Yoshimura RS-4 was designed after extensive testing and the results are profound.
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 350 SX-F.
Pro Series Full Systems include an RS-4 muffler, titanium header, Titanium or Carbon Fiber tail pipe, AMA Pro Racing insert, all necessary hardware, and detailed installation instructions to get you moving.
