Yoshimura Signature Series RS-12 exhaust systems deliver huge power at a very light weight! These systems offer better handling, thanks to a lower centralized mass coefficient. Systems feature a uniquely-styled muffler body with a carbon fiber cone end cap. Front cap design functions as a polyresonant chamber to lower dB output, while improving mid- to top-end power. Two-staged, stepped baffle tapered headpipe delivers optimal flow and performance.
