BeauCefus I wouldn't worry to much about your truck and having a cat, but you always can go to Ford and give them your vin # and they can tell you I your truck came stock with a cat. The worse thing that you will have to do if they say anything at the emissions place will say is that you failed for not having a cat and then you can get a cat and your good or they don't say anything and you don't have spend the money on a cat.
