The race bred R-11Sq R is now available from Yoshimura R&D and goodness... these Race Series slip-ons are absolutely exquisite.
The R-11Sq R dual slip-ons are available in a satin stainless steel and a beautiful blued titanium sleeve, both with beautiful R-11Sq R carbon fiber end caps and custom made carbon fiber heat shields. The shape of these mufflers is unmistakable and pays homage to the Japanese racing heritage of Yoshimura.
The performance and sound of the R-11Sq R is unmatched. These duals not only remove up to 11.4 lbs. of weight from the Hayabusa, they add up to 1.1% more HP @10,900rpm and 1% more torque @10,900rpm
Yoshimura's R-11Sq R is designed, developed and manufactured in Japan.
