New Y-piece section to complement slip-ons for GSXR1000 K7-K8 models. Yoshimura Japan are proud to announce the availability of a new mid-pipe, or Y-piece section, which replaces the catalyser on the 2007-2008 model Suzuki GSXR1000 sportbike. The new part is designed to appeal to trackday riders or racers, who want to release the maximum horsepower from the mighty `Gixer Thou' motor. There's also a handy weight saving to be made by fitting the Y-piece to replace the standard pipework.
