Default Exhausted-- Cats or Cats

Ok, here is my question... I was thinking about adding full length headers, eliminating the cats or retaining the cats.

I assumed elimination of the cats will be worth a bit of performance but was told its possible with the addition of "simulators" or editing the program.

Is this worth pursuing? Or after all the hassle and expense is it nearly just as well to retain the cats?

My buddy's car kept getting error codes with the simulator, but that was 5 years ago, perhaps they have the problem solved?

I would think getting the rear o2 codes turned off by a tuner would be better then the o2 sims.
