hot side piping size
Right now my car has 2.5" hot side piping. Is it worth it "300 dallors or so"to change to 2 1/4" piping to help get the exhaust flowing faster? I went with a little smaller turbo this time 1.10 ar 92mm wheel old turbo was 1.39 ar and 103mm wheel should I wait and see how much sooner the New turbo spools or go ahead and redo the piping and get the spool as soon as it can be this is on a 5.3
