Here is the
picture from Andrew's email.
My exhaust is stupid loud. I've
tried a few things which didn't work.
Getting noise complaints around the
airport while testing.
Just reading this Gary Schwarz's
link, looks promising. Andrew, did you
fit yours inside the cowl? I'm
surprised 5mm endplates are holding
up.

nothing to it.
I read about the
idea by Gary Schwarz
in this
thread,
post #7 , post #58
for his testing and
post #142 sums up
his findings.
Someone on here
may know him as he
was doing it for a
rotary. Mine is much
shorter than his
drawing below due to
space constraints
but the theory
works.
edit: Ahh!!!
deleted his
picture as too big
to post. it is in
his post #7
mentioned above
though.
