i bought a 90 mustang gt with an american thunder cat back already installed on it but i dont know what size it is (2.25 or 2.50) the question is does it matter what size mufflers (2.25 or 2.50) i buy or would a shop be able to fit either one on there
So are you saying that either size will fit? I just dont want to order the wrong size diameter mufflers, could i just measure the diameter of the tailpipes since they are cut off?
well the mufflers that are on there now are bolted right to the stock h- pipe so wouldn't that make it 2.25? I just want to be able to reuse my tailpipes
