You can kind of see the runners in one of the pics. There short, obviously good for turbo, and what I can make out, the center "plate" section,or what maybe a plenum, just appears to be a cover if anything. Looks basicly like a tube welded around all of the ports, failry similar to a 2.5 manifold, but picture it with small runners only. Hard to tell but the tubing appears to be a little on the large side, I guess depends on what he is trying to accomplish. Not the best looking thing around, but if it works.....
