Typically a MAF section needs to be at least 9" long and nice and straight.

it actually provides more velocity than a straight through pipe would

Hard to say. It looks like they squeeze the pipes at the MAf mount area, but to what internal diameter I don't know. Necking down the pipe and then expanding it again does improve velocity (like a venturi) and could provide some leaning and more power depending on the ID. The placement of the MAF inside the tube will have an effect also as air flow through a tube is faster in the center than it is toward the outside. I'd tend to doubt that 20hp number though..
