Hey Steven I had the same problem last year, HOWEVER the cats were stuffed, and I never replaced however after having the rear main done well I thought I'd change the headers to Neils, well the cats that were in there had collapsed and were no good, in a word ratshit.
Considering you drove it (don't know for how far) But I drove it like 2kms and they were stuffed. Also I'd probably suggest getting your ecu tested.
Mine came back with Air flow meter problem, ignition problem, injector problem, speed and transmission miss communications.
If your AFM isn't working correctly you'll use alot more fuel then what your suppose to. I think it is $90 bucks to have it looked at and tested.
