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.

And tossing muffler parts has been a very big safety issue. I sure wish
folks would stop trying to do mufflers on the cheap. It is going to hurt
some people and make it impossible for the rest of us to get any
insurance at all.

Anybody remember the Discovery? Mazda powered pusher. Muffler
came apart in flight and went through the prop. Fire at landing burned
the developer/pilot over 80% of his body. He lived, but this event sure
changed his life. 6 months in the hospital, and he is no longer able to
fly a plane. Big hopes and plans turned to shattered dreams pretty fast.

Please use inconel.

OK, I tried, and now I feel a little better.
