This type of manifold separates each bank of cylinders though - instead of collecting all cylinders together like OEM. They used the manifold design on the 300ZX and the GT-R. The balancing tube was necessary to keep both sides at equal manifold pressures - if one side had more pressure, air would be shoved to the other side.
I believe the idea behind this design is for better airflow and swirl characteristics, versus a huge open box like ours. No sharp turns to deal with.
