The V.A.L.E.™ system is Two Brothers Racing’s revolutionary and patent pending method of attaching our muffler canisters to the exhaust tube without the use of springs or welding.The V.A.L.E. systems allows 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.
