DP is not required for S2. As for IC, like I said, I monitored my IATs for several months and determined I didn't need it (I'm in NC). MHD is simply publishing guidelines for best efficiency of the given tune. The suggested mods are not absolute requirements, just what they suggest to get the most power. You can flash 2+ on a stock car if you want, it won't break anything.
I personally would never go catless, the smell is horrendous, the noise is obnoxious, plus I want my grandchildren to be able to breathe clean air when they grow up.
