    I can weld it. But I just need to find the time to take a close. Look at the car and inspect the whole assembly and get a glimpse of what I'm facing

    Re: True or false: must get Cat from dealership only?

    I got the P0420 about a year ago on my 2002 Deville (128k milles), had a CATCO catalytic converter installed for about $850 by a local Mufflers For Less shop. The replacement part was the catalytic converter and also included the resonator. The 4.6 now makes a low growl and sounds more like a V-8 which I personally like (the original resonator was larger and much quieter).

    Have not gotten the P0420 code since.

    Replace the whole thing and be done with it

    Replacing piece by piece is jus a consecutive headache.
