Has anyone got dyno proof of the gains going to a full 3" exhaust?

In some cases I have seen a loss of power. It depends which system you get, muffler or not... Cat-back or complete 3".

NZ, we dont have two mufflers here, thats euro thing... I can answer you since I have 3 inch just from the test pipe back, which is only a bursch (2.5) And the muffler is baffled, though the baffles are "designed" to accelerate the exhaust. (spintech muffler)

My car came without a cat/front muffler, that is the STOCK German spec and i checked this several times with Porsche ME.
I recall TonyG posting some useful data (real world) on the Borla XR-1 mufflers, the "only true free flowing" muffler in the market.

Do you mean other than the stock muffler?
