Any experts care to share their thoughts? Could one of these 3.5" pipes be beneficial on a L67 or am I just wishing and should stick with the AutoZone ricer pipe?
They went with a 3.5" pipe to gain back the cross-sectional area the lost by adding the inner pipe and standoffs. The concept works, the inner pipe isn't used to increase velocity DIRECTLY but that would be the end effect. The inner pipe/outerpipe arrangement improves laminar flow characteristics, which in turn increase velocity.
I doubt any cars shown on that site or their customers could outflow a 3" pipe if we can't with our L67'* that are pulley'd. Do the math on the cost of that intake, and I doubt the extra $$$$ is worth the unclaimed horsepower increase in that article.
In simpler terms, if a Honda can't outflow a 3" pipe to begin with, what'* the friggin' point in doing this? Bragging rights. Nothing more.
