Replacing an Exhaust and Catalytic Converter

courtesy of Bob, The Auto Answer Man

I have a 1990 Plymouth Sundance. There is a slight exhaust smell when I'm driving with the windows down. I don't smell it with the windows up. One day, I looked under the car and saw that the muffler and the pipes had holes in them. I can't see the catalytic converter, so I don't know if it has any holes in it. I am about to replace my exhaust pipes and muffler and was wondering if I should replace my catalytic converter with a high flow or just keep it off. Thanks for your time.

It is illegal to remove the catalytic converter. You will not pass your local inspection, and if a policeman decides to do a spot check, you could get a ticket and have your car impounded. Not knowing where you live, the laws vary from state to state. However, most states are becoming more alike with their rules on catalytic converter replacement.

Additionally, you don't need a high flow cat on the Sundance. It's only a 4-cylinder and not a very high performance engine either. Just a regular after-market replacement should work well.
Good Luck!
