Ya I noticed a lot of the links on the site don't have anything. Just too swamped with things I'm guessing. But please if you have any info or pics or price range on your manifolds, please share. Also can someone fully explain the "venturi" design? Is it just the kinda of rounded trumpet lookin ends on the velocity stacks? Or do the runners shrink and open back up 3 inches into the runner or what? I hope that made sense. I'm under the impression the purpose of it is to speed up the air against the walls, so that air isn't moving that much slower on the walls then the air in the middle. Is that about right? But the design on how they do it on these manifolds is what I'm kinda not crystal clear on.
