Yoshimura Works Finish is a unique offering from Yoshimura R&D of America. The Works Finish is not a coating, but a media blast finish using Yosh's own special recipe of ingredients which results in a stainless steel exhaust that after it goes through a heat cycle on the motorcycle, takes on unique coloring that looks much like those works components our factory racers use. This Special System is available now for Yamaha FZ-09 in Race Series full system carbon/carbon and stainless/carbon muffler options.
