awesome fab work...this should end well
Knew it had to be for an audi or a volvo. I don't understand the significance of the seperate flanges like that though. Is that going to create a lot of turbulance with the outside runners having more space near the flange and the others?

well bikes use seperate flanges when turbod, although with much smaller turbos and I've only seen bottom mount. They're also generally braced and very close to the frame. This one should be fine as long as he has plans on bracing it. I'm on my iPhone, but those welds look pretty good, does the stock motor have seperate flanges?

On those particular heads, yes. With two-valve engines, the intake and exhaust valves are often side by side (parallel to the major axis of the crankshaft) so there is no rule that says the ports must be on opposite sides of the head.
Many air-cooled engine (such as the VW type 1 - type 3) have the intake ports clustered together on the top, and the exhaust ports on the front and back.

All right, somebody please treat me like I don't know anything about manifold design and tell me why this thing is so bad? Where are the failure points and why? Please use "paint" and throw up some arrows if you've got the time.

Frank for the win! well sort of...
Tubular manifolds are weak as is compared to cast, but when you take more material out, like a one piece head flange, well now they are even weaker. The flange ties it all together, like a brace if you will.
