Auto Parts: exhaust, mopar performance catalog, cat back exhaust

Question
Is their a mopar cat back exhaust for a 1999 dodge avenger 2.5L V6?

Answer
Check Jeg's, Summit, or the Mopar performance catalog.  If you can't find it there, you can take some measurements and get an aftermarket muffler to fit, then have any exhaust shop weld in an appropriately sized exhaust pipe to match.  Usually any custom-made cat-back won't cost any more than a bolt-in kit.
