Replacing those converters isn't difficult but you really want to use OEM parts, which is because it really isn't a Dodge, it's actually a Mitsubishi wearing Dodge clothes. As such they are very touchy about some replacement parts and O2 sensors and converters are two areas that fit the touchy profile. Depending on which one you are replacing they can be under the car or the ones on either side of the engine. The two up front are the ones the ECU monitors and will set efficiency codes like a P0420 or 430 code. Normally I use a torch to heat the bolts and an impact to break them free. Remove the O2 sensors first or if you are replacing them as well you can leave both in the rear unit and the upper one in the front. Then you just break the bolts free and slide them out. Get the new gaskets and slip the replacements into place and bolt them back in. If you are replacing the crossover and rear converter, then plan on replacing the two hanger bolts as I've never gotten those out without them breaking off.
Parts wise the left converter (next to the radiator) is part number MR464478
Right converter is MR464479 and the rear one is MR281020
If you live in a CARB state and have no option but the OE or CARB legal part, set down before you price the parts.
If you live in a state where they are not as strict you can save a lot of money but be aware that the lower cost parts may still set a code or not last that long. Attached is the info on removal and the tightening specs. Chrysler sort of expects you to already know most of the process.
