from my limited diesel knowledge you want to get everything out of the turbo as quick as possible. So ideally youd have no exhaust but in reality the bigger the better. 2.5" is the right size to go for in reality.
What you want to go for is the decat, standard centre pipe and then remove the backbox and replace it with a straight pipe or a cut down centre pipe.
The manifold elbow part you posted a picture off doesnt need changing.
