I had both at the same time a while back, IA got installed and RS2 sold.
I had ordered the RS2 through a dealer in Germany, then something delayed
getting it (don't remember the details) so I bought the IA first.
Then the dealer's RS2 parts order showed up before I was there so I got
it too and sold it when I got home.  This was a suitcase import process.

Besides the turbo flange area, the IA manifold is a bit smoother on
the outside.  The RS2 (and stock) manifold has larger raised 'seams'
on the outside where parts of the casting mold joined.  On the IA
manifold these were almost smooth, and don't look like they've been
ground down.  I couldn't see the inside, but would assume it would
be at least as good.
