I really don't think I'd go with bigger than stock pipes to replace the cats, and instead go with the stock size. I can't say forsure, but I'm guessing it is the same size as the beginning of the catback...which is 2.5"
I don't see how you couldn't get gains from removing the cats, or at least adding HFCs. Its been proven on the LLT.
