Karibian,
I may have the solution for you, but I want Patent rights,
Royalties,
Author and Intellectual rights etc. etc....:)
When I tried to get new metal exhaust gaskets for my 13B I
almost had
a stroke. $90+ each. So, i got me think'n
and looking around my hangar. Found left overs from my firewall
insulation material Fiberfrax:
"Fiberfrax
A new material made from washed ceramic fibers with binders
added to
form a lightweight, flexible asbestos-free insulation. Withstands
temperatures to 2300 F. Excellent for aircraft firewalls."
So, I used the metal gasket and cut 4 copies from the material.
Used the old metal gaskets with one of my fresh super secret
liners
on each side. It works better than advertised. 100% leak free even
with my 1800F EGT's. Removed them after few hours and they were
perfectly white on all sides with no signs exhaust gasses
penetrating
out. Only draw back is every time you remove the flange, you
must cut
new liners. They compress and stay that way.
My hangar mate races rotaries and his buddies and engine builders
started asking how to get this "magic" stuff. Aircraft Spruce
is the
place.

My engine didn't come with an old exhaust gasket but I could make
one. Since
the material is going to be compressed between two metals (the
exhaust
outlet and manifold) why put tne metal spacer in the middle?

What's fiberfrax normally used for, just insulation?

I used it in my Cozy under the sheet of stainless on the firewall. It
is a very good insulator. Beside that, I did cover the can of my
muffler with it.
The first run was after dark, and the results were spectacular. At
full power the tail pipe was white and constant flame was shooting 3
ft aft.
The heat had no place to go but thru the tail pipe. Right away I took
off the wrap, and the flame tail was no more. Had to make a stainless
heat shroud and looks like it works fine with couple of flights
already. Had very good pictures of the whole episode, but when i
tried to download them, they were gone?

Got any pictures of the new muffler you can send us?
