I have an 81' Z28 and I want to put on a new exhaust but do I still need the Cat. Converters? I live in PA and it's not a daily driver by any means, but i'd like to get rid of those damn things if I can. Anyone know what the laws are on having to keep them?

 

you will have to call your local DMV and find out

 

If your car doesn't have to get inspected or emissions tested, then you don't need to keep the cat.
