I think that this is getting off topic.

Basically what I'm refering to the idea of velocity, the bigger the area it has to fill means that it slows down right? (same idea as ports on heads), I believe that's volumetric efficiency, that's why 1 1/2" headers will yield better results on a stock engine. I'm not saying you won't gain power, but there is some drawbacks to it.
