The ‘BIG BORE’ 2-to-1 Pro-Comp System features an innovative exhaust mount assembly, large-diameter tubing right out of the head down to the collector assembly and aluminum muffler housing that delivers their signature sound. An upgraded subframe assembly and bag support kit is also available. This system was dyno-tested and developed on our friend Ride Fish’s Bike! Bringing in 130whp and 135ftq. Great numbers for the 112 BBK kit installed on the bike.

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 long-awaited Challenger Full System from Toce Performance not only offers significant weight savings it also allows the bike to breathe much easier with the 2-1 equal-length headers. Held tight with an engine-mounted capture bracket to ensure no flexing of the exhaust components, and good as factory mounting. Their optional billet subframe assembly and bag support that does not interfere with cages or highway bars makes for the perfect setup. You can order the subframe with or without the left-bag support for a sleek look, and option to run another unit.

Made in Manchester, Connecticut USA – Toce Performance Precision CNC Bends the header assemblies, manufacturers all the billet components, and hand welds all of their units in-house.

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 their 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.

Note: Lead time is 2-3 weeks for production.
