Hi Dave,

I sent the relevant pics to the list, but I'm happy to send you everything I've got if you want. I have no data at all; just the pics that do show configuration, and hint at internal structure via the weld lines that are visible.

Thanks Charlie,
Those are some good pics.
 
The main advantage Al's design (besides bringing the DB level down) is the fact that there is no packing material involved. 
That's a real vulnerable area as was proven by Mistral and others. 
 
Thanks again.

Looking closer, they're pretty small and only a few are relevant. You can see at least some weld detail on the turning vanes mentioned. Here you go:

I've got a folder on my network drive with Al's name on it; it contains 10 pics of his installation (probably...).

So as to not overload the list, would you like me to send them to you directly?

This is the only one I could dig up that showed any of Al’s exhaust. Is Al still around? Did he get it flying?

Does anyone have any of the drawings from Al Gietzen's exhaust system as it was installed on his Mazda 20B Velocity (N755V.)
