Someone described a muffler:

Inner tube 4" of  stamped perforated tube (300mm long 1.2mm thick)  - filled with
very tighly packed fibreglass. The ends of this tube are sealed with a half dome end
plate 1.2 to 1.6mm thick.

Don asked:

Will the fiberglass packing survive the exhaust heat of a rotary???

Paul Lamar responded:

Not likely.

Hans disputed: :-)

Sure it will survive!  For 15, maybe 20 minutes.

Does anyone make Inconel wool?
