I really appreciate what you are saying, and I am not saying a dyno is all important,
but like I have mentioned before, there is many myths about pipes. The idea that
there is multiple pipe set-ups because of track conditions is one of those myths,
and a source for fuel economy issues.

The best pipe and engine combination is created completely separate of an track
conditions. An engine set up this way will have the best acceleration before and
after the peak, and the greatest peak HP.

Then it is up to the tuner to adapt that set-up to the current track conditions.
