Stainless Headers Mfg. header flange kits come with the stubs formed and welded in to make custom header fabrication easier.

Each flange has a 2" long stub welded on the mating surface and stitch welded on the exterior for bolt clearance.

The flange is then surfaced for a superior gasket seal. Made from an American made 304 stainless and purge tig welded, these flanges with stubs will get your header project off to a great start. Specify tube diameter when ordering. (We carry almost 300 flange patterns that we configure as a set with stubs)

Depending on the tube size combination, the tube stub may go through the flange port or sit on top of the flange-call for details.
