Is this comparable to the Hooker 2055's y pipe? Olso I'm a bit puzzled at a post I read on 3'rd gen with a guy stateing that he had 92 lo3 with a stock manifold and a catco 3 inch direct replacement and the muffler shop told him the Mac would'nt line up. Should'nt all 82-92 line up equally the same. the Mac is for a 3 inch cat right? I just learn as I go.
