today I was at my welder's, tom phillips, and he showed me a muffler he built for a rotary race
car.  I will try to get some pics.  the core is .065 321 stainless with many, many 1/8" holes.
this is wrapped with a special SS wool, costing several hundred dollars for a big roll. Tom said
that once the intake manifold cracked and the EGT's ran up to 2400 degrees and didn't burn up the
muffler.  the whole thing is quite stout, weighing perhaps 20+ lbs., maybe 8" dia and 30" long
with the center pipe maybe 4" dia.  Tom works on mostly race cars and custom cars and used to race
Indy cars himself, so this isn't just some shade tree mechanic.
