Aftermarket turbo exhaust manifold?

Bill, that sounds like good advice (put a turbo flange on a stock type exhaust manifold). Or maybe put a turbo flange on each half of Dutra Duals. But I gotta know, where's the Aussie turbo header from? These pics, are they the Aussie header or your own? If they're your own, I'm completely impressed; that's some terrific craftsmanship. Looks like an O2S port at the turbo flange...but what's the 2-bolt flange connection facing the sky for? Intake heat...?
