car now with REVO stage 2 flash and straight pipes no cats. Runs well, spools fast, pulls hard, no CEL's.
Sound is about the same, straight pipe with or with out the cats.
Thanks everyone for all the info and insight!!

Its funny I just had a CEL code P0420 on both banks after driving from Chicago to Norfolk (for reference 100 cell cats, EVO intake, DV, Stage 2 etc).About 75% of the way into the trip the CEL tripped. I had been driving easy and keeping a low profile on the turnpikes, etc. I took the car to Eurosport here at Virginia Beach, they read the codes and reset the CEL. I left happy, about 30 miles later the CEL tripped again. I called back and after finding out the code meant high emissons on both banks and knowing how gently I drove the car down I decided to do an Italian tune-up. It worked, I went back had the code read just to be sure they were the same 0420, they were, had it re-set and no issues now. Just had to run through the gears a few times. 
Of course YMMV.
