You most likely have two catalytic converters; the main one is built into the header/exhaust manifold and then a second one after the flex pipe.
Only way of replacing the first one is find a duratec header that has one in working condition (i.e used from a junker or new from Ford.) That should be a pretty straight forward swap, only real issues is working around the heat shields and tight bolts.
