What is funny is that the guy who invented this "V" design for the 993tt, Herr Pietz in the mid '90s also focussed heavily on the flow of the intercooler, possibly because if one actually measured the cooling it did it was actually worse than stock

Its nicer looking to have cast end tanks but the gains will likely be minimal (or none) over a welded solution.
The most important tank will be the inlet one as getting good distribution of airflow over the cores is important (the stock one is reasonably good at this).
The V in the outlet tanks almost certainly does very little apart from reduce the intercooler volume by a tiny amount. It could be argued that this reduces lag by reducing the volume between the turbo compressor and the inlet valve, but if compared to the total volume of the piping, plenum etc. it can't make an appreciable difference.
The most important thing with intercoolers is the core design and efficiency. As TB will allude, this cooler could well be worse than stock and so under continual (autobahn) or repeating (track) load could give lower performance.
That said a larger intercooler can act as a heat sink and so can be better for short runs.
With most of these performance parts there is little proper data on which to make a decision. With intercoolers, without this data it is probably best sticking with stock (if you're interested in performance rather than looks).

I heard the early prototype had even better airflow!
