Alright, well, for a build I am going to be doing I can choose between 2 4" aeroports, or 1 6" aeroport. When I put the 6" into WinISD it tells me a length of 23.25" is needed for my tune. And when I enter 2 4" ports it tells me I need a port length of 21.5". Now, is that a combined length between the two ports? Or does each one need to be 21.5" ?? Thanks for your help.

    Not a combined length, both 4" ports will need to be 21.5" for that tuning.
