Lynn,

Thanks, I'll check the Mistral site.  At least what I'm running now is durable, not the quietest on the field, but durable.

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.

Hopefully it is an improvement on the last years model made by a third party, that decomposed and blocked the outlet, bringing the test plane down.
 
Muffler design is very serious business.
