Since, there seems to be some interest in mufflers, I though I would make available (for those interested) a Naca report

On exhaust muffler design.  Too large to post to the list, but if you are interested, send my an email to eanderson@carolina.rr.com

and I will send you a copy.  Warning the file size is 6MEG, so unless you have a fast internet link and your e mail provider does not have a size limitation of files, I probably wouldn’t recommend me trying to send it to you.

Below is the title and an extract of the table of contents to give you and idea of what it contains.
