Kelly,

You just need to fly at Mach 1 so you stay ahead of the sound.  ;-)

Can anyone report on the effectiveness of the tangential muffler in actual
real world situations?  (As I recall Al G. is running a tangential muffler
on his Velocity.)  I ask because I'm in the process of building one for my
Lancair with the hopes that it will work better than the DNA muffler that
I'm currently running.  I think it will work better at reducing the noise
level in the cabin, but at what cost to power?  Hopefully, this will save me
the cost of a new Zulu ANR headset.  Comments appreciated.

Mark S.
