I would find out what they are packed with Don before you buy one.
The 13B is good at digesting muffler internals and blowing them out the
exhaust pipe.

Since the rotary loves to eat the innards our of mufflers (and the muffler too), I was thinking of an alternative material to pack my muffler with. (Here's the wierd part) I have an Eheim (sp) aquarium filter that uses a ceramic medium that just may make a good packing material. (I warned you.) The ceramic pieces are about 1/2" X 1" with approx. 1/4" holes running lengthwise. They sorta look like noodles, only made of ceramic and should be available from any tropical fish store. Would ceramic make a 

good packing material? Can it handle the temps of the rotary?

I'll crawl back into my cave now...

I don't know Marc.

BTW Tony Bingelis mentioned in his book Firewall Forward  that continuous strand 
woven roven fiberglass stands up  better than fiberglass wool in mufflers.
