I know what you mean ... but the Hooker chamber is said to use the same principle as high velocity collectors on LT's to speed up velocity and thus increase flow ... dunno if that makes the case for the aerochamber or not. I do know that Damian is a highly credible guy with tons of experience on such things.

Personally, I run an Hooker Maxflow which is straight through like a Magnaflow - 3" in, 3" single outlet.
