I have asked my dealer techs this same question. according to them the o2 senser (which its the issue) is maped into the engine management system. you would have to remap it. I don't know if the cob unit will help but there doen't seem to be any other posible option for that avenue. There is also the idea of tapping the o2 senser into the pipe you are using instead of the cat. I haven't gotten that far yet but would like to know how you make out.
good luck.
good luck.

The CEL is because there is no CAT....the PCM expects the front WB and the after catalyst NB sensor to do certain things with the testing protocol the PCM uses.....when the PCM sees something it doesn`t like ( IE no CAT 
) it sets a CEL for poor Cat performance
You can use the AP to mask the CEL ( ie ignore it ) Or replace the CAT....either will get rid of the CEL.....
There is no way too fool it like older OBD1 cars.....
