I don't know what it is about this truck I went to pep boys napa and advanced auto they are always so confused by my system. The stock pipe auto zone gave me was totally off it was a 2 in. I was trying to make my flow master setup someone had a Gibson cat back on it, but anyways nobody could actually give me the right size so I said screw them and went under there with a dial caliper mine is 2.5 cat back all custom made and stuff. No idea what the normal size should be bad every auto parties store sucked.
