carbon smith velocity stacks

Thanks for posting the pics. Is the shorter one the outside or an inside stack? I know before FI with RAM air you actually jet the inner 2 carbs richer (larger main jets) because they get more air so I assume the staggered heights must have something to do with equalizing the air flow? Just curious. They also look more narrow (or is it just an artifact of the pic and shorter stacks) so increasing velocity? I would love to see dyno charts after a retune.
 
i didn’t measure it with calipers so that might be a question for the manufacturer to answer. the oem are thicker and have a more “durable” feel to them. the inside diameter matched the throttle body so i dont think it will affect air flow for that reason alone.
 
Nice stuff. I could be wrong but those stacks, shouldn't they be smoother on the inside, seem a bit rough.
it’s a $100 “upgrade” and supposedly adds a few hp. that question can turn into a whole debate on its own. on some application i believe it will be beneficial but on others i doubt it.
