This is basically an 'acoustic' version of adjusting antenna feed-tuning as done by CB'ers for their antennas. Where the "standing-wave" occurs, the pulses will be strongest & hottest...the "sweet-spot" for those TIGs.

Of course, this is only valid for one RPM (ie: highway cruising at a set speed), but something possibly worth considering?
Very cool idea.
