MHD 2+ without DPs

I remember seeing in a post a while back (on another forum), Wedge saying that catless down pipes aren't NEEDED in a Stage 2+ flash. I don't remember the specific details, but it was something to the effect that they haven't actually been proven to improve hp in a Stage 2+ flash, and he said they're really only needed if you're upgrading turbos.

What are your guys' thoughts on this? Would this not be harmful to the turbos? Or does a Stage 2+ flash not produce enough boost for it to be dangerous?

(PS - I'm asking because I recently swapped my stock DPs back in for smog and don't feel like swapping the catless ones back in)
