Paul,

Here are some pics of the proposed headers.  I am thinking about cutting out
part of the vertical  tube that causes the double 45 degree tubes to be used
to go around it.  The system needs tweaking like adding slip joints and
designing brackets to support the headers.  Appreciate any input.

That is about where you should start your ejector outer tube
cooling air input bell mouth. Also you need to put a tapered nozzle on
the ends of the exhaust pipe.
