I'm getting ready to paint the plane...but right after that I'll let
you know what this baby sounds like - my guess is it's a screamer :(
It doesn't have a "cool tube" in the center - but it does have a heat
shield covering 80% of the exterior - the open 20% faces the engine
and allows cowl pressure in - then out the cowl opening with the
exhaust tubes.

From the "other" list comes the report that someone has tested a
similar exhaust system to what I have been building on his
PowerSport p
ported engine. . He reports the muffler worked well to quiet the
exhaust note and that the engine seemed to breath freely. The neat
thing about this exhaust system is that it fits inside the cowl.
Here are a couple of photos showing the muffler on a Mustang 2. The
muffler is 6" o.d. x 10 inches long. Construction is 321 16 gage.
The cool tube running through the center is intended to cool the
exhaust gas. Fresh air is plumbed through it. The engine mount is
the S-beam. Jerry
