Turbo manifolds
Thanks
And the easiest/cheapest thing to do is find some decent stock manifolds or shorty headers with a respectable ga. steel and use/modify them.
I was able to cut flanges out here at work on our laser to make my stuff and could get you to send me a .dxf for what you want but it is currently not working all the time and when it is, there isn't any time for "special" parts to be cut
