David,
I am I believe many of the listers here would be interested in reading more
about this exhaust, and would appreciate your efforts in placing a link or
copying and pasting the article.
As was discussed earlier here, the consensus seems to be that as long as you
are not distributing the article for profit, there should be no copyright
problems.
Having reviewed the link below, I cannot find any discussion of the exhaust
or the noise level of the exhaust. Could you indicate where that occurred
in the link?
