Ernest,
 
That's very interesting... I may need to study this more carefully when I have some time to really concentrate.  Do you know of anyone that has actually built a muffler utilizing this technique?  How did it work out?  Any drawings/sketches/pictures?

Mark,
Take a look at the newest Mistral pictures. They are using a tangental with a "cool tube" something that I drew several years ago for PL's site. They use a large down pipe with a annular exit around the tube. If you are doing something new it is worth a look. Material is 321 I think.

Does anyone else get "Make" magazine?  One of the things I want to try is creating a phononic band-gap filter.  I'm not sure of all the details, but it I think a tangential entry to an array of 3/8" stainless cool tubes, with a large central rear exit.  Do a google search for "phononic band-gap" if you don't know what that is.
