Gun suppressors are simply a tube with multiple baffles in it
with the center holes just bigger than the projectile. Then
remember there is only one shot to silence at a time. Again I am
guessing, but it seems that the stock exhaust header does silence
the noise some what as well. I know of a set up that uses the
stock manifold into a muffler and is does a great job in noise
elimination. The manifold I am cutting down weighs almost 10
pounds, (with the end cut off). so while this weight is
significant, it i appears to be good "value"
Mat, no consolation, but I also have a perforated tube sitting in
my shed destined to be the final "quietener" on my setup, (aka
Paul Lamar) but you have saved me the trouble as it obviously does
not work. It would appear that a muffler made of inconel with
internal baffles like a rifle silencer may be simplest. Baffles
made like multi blade impellers to swirl the exhaust as apparently
"rubbing" the gas will help quieten the noise.
Heat in exhaust. Mat I spent years worrying to death about take
off heat at 1800 degrees as I had an exhaust gas temp sender. My
mate had no such probe and flew for years in bliss as to exhaust
gas temps. When he finally pulled his engine down, it was perfect
as to any damage due to hot EGT. This however, is a worry for a
turbo. Supercharger eliminates this worry, but I need the
"muffler" effect like we all do. All compromises as usual.

I would really like to hear from someone like a gunsmith
who has experience in the design and construction of
suppressors.
They typically devoid of any packing to collapse/blow out.
As I recall, Al Geitzen had a similar setup on his 3-rotor.
