So I have plans that call for a port 2 3\8" diameter by 5 1\2' long. I cant find any PVC that diameter. How to I figure out how much two smaller diameter ports should be?
Nevermind. Im an idiot. Wastn paying attenion and the plans call for 2" PVc for the port, whch the outer diameter of is 2 3\8"
None the less, if you do decide to retune your ports, here are some links to port length calculators that you can use.

You can also use these calculators to determine at what frequency you are currently tuning your ports.
Just enter the port diameter, internal box volume, and keep changing the desired tuning frequency until it gives you your known port length.
Just trying to help.
