The 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/aluminum 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.
