This is where the magic happens

and the most tricky, there's two pieces grafted together here.
The idea is to get as much space/volume behind the turbo, and so as little back pressure as possible. FLOW is good. Trouble is there's not a whole lot of space off the back of the turbo to the bulkhead, especially when you allow for engine shake etc.
