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  Yamaha YZ250F and YZ450F.

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.

          nice looking exhaust with power increase. damaged the stock one so it was time for an upgrade. A friend recommended this system to me and I love it.
