If you haven't replaced it yet try going to a muffler shop, they will charge a lot less to replace your catylitic converter. Hundreds le$$!!!! I replaced one on my car for about $150, that was including the labor, with a lifetime garentee as long as I own the car. Try to go that route if I am not too late.

Man did you get ripped off, was it at least a brand name muffler shop? Got my grand am's entire exhaust replaced for about $350. Where did you go? I aways go to a locally owned shop, they are always less than Midas and places like that.
