Dude if you search JF for a Catalytic thread from a while ago, the US GOVT covers Cats up to 80k. I got my entire assembly replaced by the dealership at no charge. And my warranty was up. I posted the link in there to the documentation on Chrysler Website too. If I have time I will dig it up for this forum, because it is goo info. Saved me like 1k.
Not sure if you are over 80k though
