The Yoshimura R-11SQ R slip-ons with EEC-approval

R-11Sq is the highest grade silencer evolved from R-11 and it is developed through the Yoshimura race scene. The square tapered shape enables to have enough volume to control exhaust noise to meet race and road regulation without sacrificing performance. The R-11SQ R is the latest iteration of this exhaust type with a Euro4 EEC approval!

No need for the EEC approval? Find here the R-11SQ street sports versions!

For those who don't need a certification in their region, we have some slip-ons in stock at a lower rate. Please be aware that these slip-ons are not road legal in the European Union!
