I did a search this morning, and found some very good information.
I did find one thread that says the factory cats are not high flow, and to make sure and change them because higher exhaust temperatures will burn them out prematurely if you don't, and its even more important if you have a super charger.
Here are some of the threads I found in case anyone is interested.

I do have an appointment to have the existing check engine light fixed tomorrow.
P.S. dont search for the word cats, it really pulls up some c r a zy stuff!
