Welding a Exhaust Manifold

Bolt an hp flange to the manifold along with the broken piece in place. Make sure the flat (gasket side) of the flange is not the side that is welded to the manifold. Thick lazer cut flanges are best and are flat on both sides unlike stamped flanges. After preparing the manifold for the welding process ( wire brushing, grinding etc.) weld the flange to the manifold and to the broken piece. Weld the flange 360 degrees around where the flange meets the manifold. Stronger than new. Works every time. The extra amount of distance this process drops the exhaust pipe ( approx. 3/8") is negligible and rarely causes an issue.
