The Yoshimura RS-4 is a technological marvel. It features a Yoshimura duplex chamber which cancels out negative exhaust pulses; and effectively acts as a mechanical baffle before the actual perforated baffle area. This in turn improves power while lowering dB.

Stainless/aluminium muffler construction with carbon fiber tip and a 96dB spark arrested insert. Optional inserts available are motocross 99dB non-spark arrested insert, and 94dB motocross non-spark arrested or 94 dB off-road spark arrested insert. Stainless tailpipe bolts right onto stock header for easy installation.

As the official exhaust of the Yoshimura Suzuki Supercross/Motocross team, this 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 YZF250.

This Full System comes with a stainless steel header and mid-pipe, aluminium muffler sleeve, installation hardware, and detailed instructions to get you moving!
