On any other car I would agree, a cat back would be great, but I refuse to spend another dime on this POS car. I've seen other contours that lasted forever, and mine is a total POS. See my post "Anyone Else" in the general forum, and you'll understand. This car wasn't my first choice when it was purchased, and every time something else breaks I hate the car more and more. I should have kept the 1998 mystique I had, it had leather, it was black, and it was a really good reliable car. I am regretting I got rid of it.
