Brian's system is a true equal length and not a twin scroll system.

Thus, I am guessing the cross over might be a positive on this type of a system.

A cross over connection probably helps to further reduce the peaks of the amplitude of pressure changes inside the headers. This is mostly the same thing an equal length system dose.

The net effect being lower back pressure and even more orderly exhaust.

Anything that sooths the highs and lows should let it better flow, with lower restriction, less noise, and less back pressure.

Said lower back pressure's further aids cylinder filling and increases VE.

I could be mistaken but this is what I am believing at this point in my education.
