I’m in ny and building a 408w. It is a 1996 so in a year or two when I register it it will be more than 25 years old and will not have to actually pass an emissions test, meaning I could take everything off and they can’t do anything about it number wise. Problem is, they still do a visual inspection. I’m wondering what the bare minimum I need for them to say yep it’s got the smog stuff. I would love to get afr 205’s for it but they don’t have any of the smog passages so I wanna make sure I can still pass. I’ve heard that those crossover passages don’t do anything besides direct the air from the pump only when it’s cold and that I might not need them to pass the visual inspection. Can I just get the 3 way or high flow cats that don’t need the air pump and not need it or will they still fail me because it’s not there? Thanks guys!!
