There will be zero gain to be had by removing the cats unless you are also upgrading the headers to some that flow well. The rear muffler isn't actually that restrictive, but the factory headers are horrible.
As to CELs, you will get a catalyst inefficiency error due to the lack of difference in pre and post cat O2 readings. You can either flash your DME to RoW program with a PST2 (which ignores the secondary O2s), or you can try locating the secondary O2s after a spark plug defouler, which may work.
