Does anybody have drawings of a succesfull muffler yet? I put two

straight through 'hot dogs' after my expansion chamber, dropped the noise to
the just tolerable level. I need something a bit better and lighter.

This is Tracy's latest muffler design. Are you still flying with it Tracy?
BTW Ian got any pictures of your airplane you can send us?

OK Paul,
I've been playing around with mufflers for some time now - but I give up on
that drawing.
Please explain.
Is that square tube going into a round tube - for the life of me I can't
work it out.

That is Tracy's "drawing" :-). It is a round tube about 3" or 4" in diamter
amd about 4' long under the center of his RV4. Tracy is this about right?
How about some dimensions on that "drawing" :-) ?
