100%

The R1 Slip-on Exhaust is the patriarch of the Toce Exhaust Line. Originally designed to accent the tail section of a 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 handmade right here in the USA.

Constructed of Chemically Certified 6061-T6 & 6063 Aircraft Grade Aluminum and loaded with a 304 stainless steel spiral welded perforated baffle assembly + ISW Packing. The T-Slash quad exhaust system from Toce Performance is one of the company's best sellers, made right here in Manchester, Connecticut USA, and is hand-welded; comprised of all in-house designed and machined CNC components.  Put in place by a precision mandrel bent stainless steel header assembly and when paired with our ECU Flashing service + MWR Filter Combo, completely opens the bike up to its true potential while standing out from any other setup on the market.

Toce Exhaust systems are all designed for each application. No two systems are the exact same, nor are they generic muffler assemblies held onto bikes with universal band clamps. Each one is designed for its application and made in our facility in jigs, to ensure perfect fitment. This is why Toce Performance offers one of the most comprehensive lifetime warranty programs that offer more to its customers than anyone else in the industry.
