Paul, looking for a little brainstorming feedback.

Are you familiar with the x-pipe crossover, like the Dr Gas or Bassani
designs?  The X-pipe directs two gas flows into each other; reduces
noise and creates a scavenger effect with normal V-8 automotive exhaust
systems.  I wonder if it might work in a rotary exhaust to reduce some
of the heat/noise energy before it gets to the muffler.

In addition, Ive been wondering if either hi-pressure air from a scoop
or possibly lower pressure warm air  exiting the cooling system might be
routed into an exhaust collector, possibly as one of the legs on an
x-pipe or as a third inlet in a normal 2to1 exhaust manifold.  This
idea is a spin off from one of the circular air cooled muffler designs
you?ve posted in the past.

I don't understand the theory on how it works.

I need some sketches on the second part.
