I was surfing through the net, when I remembered reading your post. So with a quick search, I found a similar setup from Borla induction.
They sell a kit which includes 2 manifolds, ITBs having the same bolting pattern as Weber DCNF, air horns and airbox/filter.
It will be very logical to ask them if they sell the manifolds alone without the ITBs, as a separate part. Or maybe if you're interested, you can use the ITBs instead of the carbs, along with the OE fuel injection system. Trust me, ITBs DO sound like carbs.
Anyway, I'm not going to post the link here, so PM me if you're interested in it.
