Featuring mandrel bends, the entire Ultra spec Titanium Medalion is 100% SUS304 stainless steel, 1.2mm thickness, for maximum weight reduction and optimal durability. Stainless steel is used throughout the system from the exhaust hangers to the canister band clamps for enhanced appearance and increased resistance to the elements. 2.5mm or 7mm flanges are used throughout the exhaust for the various temperature sections. Argon welding is used on all of the stainless steel components.
