The carbon fabric is made with a 33 million modulus carbon tow then impregnated with the high temperature resin under very tight tolerances. This allows Two Brothers to make sure that the fabric is impregnated with the exact resin content every time. Then each exhaust is place in an autoclave to cure under full vacuum. The autoclave also removes any volatiles and air from the carbon fiber. The Silver Series exhaust system comes in your choice of aerospace grade Carbon Fiber or 6061 T-6 grade aluminum.

The V.A.L.E. system is TBR's revolutionary and patented method of attaching their muffler canisters to the exhaust tube without the use of springs or welding. Their V.A.L.E. systems allow the muffler assembly - exhaust tube and canister - to be positioned perfectly on the bike before all the mounting hardware is fully tightened. Once the canister and exhaust tubes are properly aligned, the V.A.L.E. assembly locks the muffler canister to the exhaust tube assuring a perfect, leak-free fit.
