Yoshimura - RS-4 Exhaust System (Kawasaki)

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.

As the official exhaust of the Rockstar Makita Suzuki Yoshimura Supercross/Motocross team, this exhaust 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 KX250F and KX450F.

This Full System comes with a titanium header and mid-pipe, Titanium or Carbon Fiber 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.
