I agree with you, but a muffler is not a pressurized sealed chamber (as your mouth would be).
If I placed the smoke nipple next to the pressure nipple (side to side, tapped onto the muffler body) then it would be just like you said.
Now picture this.
Lets suppose that I plug the pressure nipple to the tank and I hold the other line in my hand (where the smoke fluid will come out).
As soon as I run the engine, hopefully smoke fluid will come out on the other line (the one I'm holding in my hand).
With the engine running, I take the line I'm holding and insert it inside the muffler exit.
Would the smoke fluid stop flowing? [sm=confused.gif]
I understand about how excited you are over this, so I really hate to say it. But you're getting it way overcomplicated.
