Bad bad idea, unless you're only paying 200 bucks for it. The seller is feeding you a line of bull in order to dump it. I'm making bets it'll need a lot more than a cat to make it pass emissions.

That is one worn out pile of junk.

Wellll, you better fix the rough running because if it is running rich it will "cook" the new converter in a very short time.

Do it gut out the cat on it and put a pipe threw it and straight pipe it you can pass inspection with any light on

That's nice. Did you want to ask a question?

Looking to buy this van next week .. Been told it will need catalytic converter.also been told it starts up and run but it runs ruff. .
