How much of a difference, really, do you guys think there is between the aFe and SuperSprint offerings, power wise? I'm seeing that you guys say smaller is better right after the headers, whereas aFe obviously disagrees as they went out of their way to increase the sizing of that section of piping (even though their flanges are the OE sizes). According to aFe that is to "maximize efficiency and sound" or something to that effect, but here I am seeing other views on the matter. I haven't bolted mine up but hearing of potential low end TQ loss has me second guessing them.
