alright so i recently just purchased a set of pacesetter longtubes, a 3" y pipe with a flowmaster cat back(80 series) for my 95 z28. my first question is that i ordered the long tubes with no e.g.r or smog hook ups so what type of code(s) is it going to throw? and is their any easier way of getting them in because im in the process of lifting the block to slide them in and could use a tip or two.
