DP with AP

Slops' video clip shows really nice smoothness in the acceleration with the AP. I did notice the SES light on, resulting from his DP.

I have a couple of questions for Cobb regarding DPs and upcoming Stage 2 maps on the N55 -- since I'll definitely want to be able to run Stage 2. First, is a DP definitely required to run the Stage 2 maps? Is the answer the same for RWD and XI cars? The XI has secondary cats in back of the DP, whereas my RWD car has cats only in the DP, and I am reluctant to get an aftermarket DP. (Note: I already have FMIC, chargepipe and drop-in filter on my car). If better exhaust flow is essential, could an aftermarket exhaust be an alternative to a DP, would that help much for a RWD car?

Second, are there any future plans for the AP to eliminate the SES light when running a DP?

Thanks.
