Alright guys, im in no way a car expert, thats why im asking this q. My exhaust system is factory from my 84 z28 and needs replacement. Ive been looking at this board and see that a lot of guys are getting rid of their cats and putting on a good muffler. Would yall suggest that for my new system? One of my friends told me this is illegal, is that true? Im on a tight budget, so what would be the best setup for my car?
