help with exhaust

I would check those vaccum lines capped and capped correctly. Otherwise it might have a vaccum leak and idle rough. Do you know what engine you have? If it is a 305, they don't sound that great. I was just running the original cat - no muffler for a while and it does sound ok at idle, but reving it up didn't sound great. It would be useful to put your location in your profile so we know which state we are dealing with. The law is (at least in CA) your cat has to have 50,000 miles on it or be damaged to be replaced. If your having trouble finding a shop to do it, I suggest you beat the hell out of your cat or saw it of, then take it to a shop. They should have no reservations about replacing it then. My cat started shooting out the pebbles inside so I had to replace it.
