Hello 'Stangers: I'm new at this forum so bear with me. My '66 K code 2+2 is in the middle of a restoration back to mostly stock, which was a 2" diameter exhaust system. I want to use the cast iron manifolds which have a 2" outlet (actually 1 7/8"). It looks like there's enough thickness there to hog out a little to increase the opening. Is this advisable? Would I get any benefit from going to a 2 1/4" system? Does anyone have any experience with aftermarket iron manifolds? Thanks for your help.
Mike
