I reckon that by varying the placement and lengths of the t00bs fore and aft of the 'x-pipe' section you can further tune the resonant frequency.... Get good midrange gains while developing an especially fat power curve in a narrower RPM band.
Dave have you considered doing any intake manifold work?

I would like to hear the theory behind it. I'm guessing the gas is at a higher velocity in the smaller tubes, and when it crosses over before entering the big tube, it creates a slight suction effect on the other side.

Thats the very principal through which a header works.
Although its not 'suction' is pressure differential (delta P) thats at the business end.
