The twin piping is constructed of mild steel with a titanium particle coating mated to SUS 304 polished stainless steel canisters. Each canister features a polished 90mm (3.54 inch) tip. Robotic TIG welds compliment the hand crafted MIG welds to create on of the most innovative and dynamic exhaust systems on the market.
