Just because half a dozen people have those turbos, doesn't mean they're all maxing out their 3" exhaust. You're looking for people at that power range or higher who have also done back to back comparisons with either timeslips or by measuring exhaust backpressure after changing exhausts. Do you really think you're going to get multiple good answers here?

Technically it just keep exponentically expanding pressures across the board. You say pot-a-to, I say po-tat-to. I believe it is a restriction, because if you measure pressures before and after the turbine, there is a difference, no matter what's going on in the intake tract.
True it would take a helleva lot of power to max out a 3" exhaust. I'm not trying to see huge gains. Just gains or not. I'm questioning if it helps on spool time. I really don't need multiple good answers. Just one, since I understand that not many have a 4" DP. I know of 2. I'm not really willing to ask these people, since I really don't like them.
