they are both t25 flanges, the one on the right is for a True T28 and bigger turbos that's externally gated off the manifold, the one in the left is for a t25 that's internally gated..
Simple
Right = 300hp - 600hp
Left = 150hp - 250hp
It looks like a 240sx/silvia downpipe so i'm sure hes stepping up to a bigger turbo.

This is the exhaust side, imagine that little flapper welded shut (or wired shut in some cases) to use an external wastegate.
