technically yes but it shouldn't matter too much one or two inches off wont affect the sound to where its noticeable.

Yeah i kinda figured it wouldn't be noticeable to ear but which one are you saying yes to? if Torres says it needs to be 22" port i should make it 22" long or 23-24" long? total length
