The R1 Slip-on Exhaust is practically the patriarch of the Toce Exhaust Line. Originally Designed to accent the tail section of the bike to showcase the Toce Swingarms we used to manufacture. It unknowingly would change the game for our product line. The meaty, throaty sound of our exhaust system was unlike anything on the market, and offered an aggressive look, and mean sound. These systems transformed the business into what now, offers a full line of performance products for various makes and models that are all hand made right here in the USA.
