Evo 3 Manifold and o2 Housing?

[TommyDSM]

How Can I tell the difference between the Evo 3 Manifold and Evo o2 Housing form the 2g Manifold and o2 Housing? or From the 1g...

The collector on the Manifold will be already at 7cm and on the O2 housing the passages are larger, there are comparison pics on turbotrix website and a couple others but I can't find them right now.
