Dual aero port question

[scooter99]

I was looking into using a dual aero port set up for a design. In torres when I do the dual port set up and come up with, just for example, 24" of port length, does that mean both ports need to be 24 inches or does that mean each port needs to be 12 inches?

Thanks!

Each port needs to be 24 inches.
