Im thinking of buying a SLP X or H pipe and was wondering, going from the 6 cats to 2 cats, would it still pass emissions? I always thought that as long as you have cats then it will pass but now I've heard a few other things of how sometimes they still don't pass. Im located in PA also since some states have different emissions laws.
Ya im kind of interested to I have a loudmouth catback with the SLP cated X on there. I live in CA so its a big deal..... Fets were did you get your race pipes? Does SLP still sell them?
eh i'd rather just be able to put a catted pipe in and not have to worry about swapping them everytime i go for inspection, as long as there isn't a vast performance difference which there isn't im happy.
