^^^yeah i understand what your saying and similar thing goes for extractors for "scavenging effect" which is kinda the opposite.
i'm not going to argue with you either in regards to the V2 AEM intakes as i've seen them and are definately of high quality especially since their seamless and their angle-ing aren't that sharp.
my argument was based more towards exhaust shop fabrication quality as they use premade mandrel bends and weld together some pipe which ARE NOT "tuned length" obviously as you have already established. unlike AEM who stare at engine bays and use CAD software to calculate airflow, an exhaust shop will take a 1min look at your bay and fabricate the most accessible path... but also because of the welding, the inside of the pipes will have blobs where they were welded and the same thing goes for any welds on an exhaust sytem... it becomes an airflow bottleneck also similar to the ribbed factory rubber intakes.
your right on the money with AEM and their CAI
however considering the price of just the intake, i'm pretty sure the majority of people who discuss advantages between CAI/WAI are talking about exhaust shop quality which costs AU$100-$200 to fabricate
