MIG welders heat the metal much more rapidly which distorts it. It would have to be in a jig to MIG weld it to keep it all uniform to its intended shape.

This is the reason why you need the jig. The headers have been Mig welded & not Heli Arc'd (Tig Welded).
Bonneville Joe hit the nail on the head.
