409 stainless steel is superior to mild steel for exhaust piping due to its higher chromium content, which provides excellent resistance to oxidation and corrosion at elevated temperatures. Unlike mild steel, which quickly deteriorates from heat cycling and exposure to moisture, 409 stainless maintains structural stability, resists scaling up to extreme temps of 675°C, and offers much longer service life. This balance of strength, heat resistance, and corrosion protection makes it the industry standard for OEM and aftermarket exhaust systems.

These 409 stainless steel mandrel bends by GASO provide superior thermal reflectivity and corrosion resistance compared to untreated mild steel. The tube features a 2.5" outside diameter in 409 stainless steel (unpolished), enhancing oxidation resistance at elevated temperatures.  409 SS is also weldable using both MIG and TIG processes, though post-weld cleaning is recommended to minimise surface oxidation. Can be used with clamps also.
