Ok I was just wondering when measuring the port length for aero ports externally would be the same as the port calculator that you use for the internal ports?

Sorry I just forgot & need to know again.

Yes, a port calculator (like the one on the psp website) gives you the length needed WITHOUT taking into consideration the port displacement. So if ur box is say 2.0 internally, if u just want it externally all you need to figure out is the length.
