The Competition Werkes GP Race Slip-On Exhaust for the 2017-2018 Yamaha YZF-R6 takes off pounds of weight and increases performance while making the R6 look and sound much, much better. Made from the finest stainless steel tubing, it is welded instead of bent to avoid weak spots, just like a MotoGP pipe. Much more affordable than a full system. Made in the USA.
