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. If you've been striving for a competitive edge, take things to the next level with the Yoshimura Signature Series RS-12 exhaust systems! Order the model designed for your application.

* Titanium systems include non-spark-arrested 99 dB motocross insert (unless noted)
