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 square port, D-port, or round port for 2.00" primary size)
Port Size: 2.000", 2.125", 2.25", 2.375", 2.50"
Specify tube diameter when ordering. (We carry almost 250 flange patterns that we configure as a set with stubs)
Depending on the tube size combination, the tube stub may go thru the flange port or sit on top of the flange-call for details.
