What wall thickness on those fish tails Ed & Jerry? They are small so you

can

afford to go up on the wall thickness for the flat parts. I have no doubt

they

catch holy heck from the supersonic exhaust pulses vibration wise.
Note the doublers in this picture.

Don't let me forget to bring my DB meter to S&F :-)

Well, Paul, my fishtails certainly don't match up to the wall thickness on
that Merlin {:>).  Actually, mine are 0.035 wall thickness (same as my
pipe), but that is a good suggestion, so little length/weight could go up to
0.065 or more.  I seriously doubt that mine will survive even 6 feet from
the exhaust port, but will give it a try.

  By the way, Paul, don't forget to bring your sound meter to Sun & Fun.
You might ask Tracy or Finn to bring theirs, just in case you don't have
room in your travel kit.
