It's actually pretty hard to tell. The point where it meets collects from 2-1 doesn't seem divided but I couldn't really get a good glimpse all the way in. It's a very well built and pretty manifold though. I'll email you pics when I take my turbo out for some Jet Hot coating.

That seems to be similar to mine. Although the manifold flange has a divider in it, the back side does not. Both primaries merge to within say three inches of the flange but are siamesed (joined into one) after that along with the wastegate primary. Wonder how much of a gain in spool up times could be seen with a true divided manifold...
