I think its called HKS cross flow system...

When strong vacuum is created, to the contrary, there will also be strong pressure. Cylinder pipes are connected with Bypass Pipe to reduce pressure as minimum as possible. Rhythm of "Pressure" and "Vacuum" inside manifold is controlled.
Besides, number of bypass pipe, positions are designed to optimize for each engine characteristics. It enables to reduce pressure without change of vacuum. Therefore, there is no drop of torque as shown in the graph below. The engine will have Inertia Exhaust Gas Efficiency (Efficiency to increase horsepower of NA engine) and flat torque characteristics, which enables easy drivability.

So interested??

for low end or top end...?

Not really sure but (according to HKS) it supposedly improves both low end and top end, with significant torque improvement on low end.
