Hi Gunner, just in case if you have not seen my previous post, I added
more pictures of plans of the exhaust opening. Also, I made a fairly
accurate paper cutout of the opening, which I would be happy to mail
to you if you want to. See pictrues at

There is one thing here that might become a problem if you get to big of pipe
and muffler on it. Like a Chevy 350 engine with large pipes on it. The big pipe
will cause a bellowing sound or vibration with the large pipe on it. With normal
pipe on it you will not see or hear this bellowing sound. Now try what you
havebut if it bellows , you may have to do this. cut the muffler off and go to a
3/4" pipe and just shoot the vapors straight out 20 feet in the air with no
muffler or restrictions on the line. This away there is no sound till it gets at
the end of the 20 foot pipe in the air. Wait and just see.
