Does anyone run their 20B without a muffler?
I was told by an engine builder that the sound of the 20B is not as

intense as the 13B and could be run without a muffler. He said the sound was
much like

a

piston V-6.
Thanks!

I run my 20B without a muffler--but I do have a Garrett TE-06 turbo which
acts like a muffler.  I sometimes forget to activate my noise-cancelling
headset, with no adverse effects.  People on the ground tell me it sounds
powerful but not any louder than a Lycoming.

Hi Tom, do you have any details on your Lancair? I'm planning on switching to a
Legacy and using a 20B as well. Do you have a web site with your project on it?
