No, a tuned pipe pulls exhaust out of the cylinder, then continues to pull fresh mix into the cylinder and into the pipe. The reflected wave then packs the fresh charge from the pipe back into the cylinder just before it closes. This is, in theory, the way to make the most power. Whether or not this actually occurs depends on many factors.

I have not tried it but I understand that you can't effectively use a tuned pipe on a diesel because the charge that would get reflected back in is just spent gasses because diesel combustion is more complete.
Yes/No?
