Question about winisd

Hey PP, On winisd if I want two 3" ports the value given is 17.xx". Is that the length I want for each port or combined length of 17"?

Yes, its the lenght of each port. Two 3" ports are almost equal to one 4" port. If you tell winisd to use a 4" port you should get about the same lenght as with two 3" ports.

Thanks!!! Reason for asking is I have one 3" port but obviously it sounds like shit (box is in cab of truck) so was gonna add another 3" but at those lengths I think I'll try 4". Thanks again!!

Correct. Two 3" ports should have as much area as one 4.125" port.
