Can this be re-written in English standard as opposed to run-on-ese? Not trying to be a jerk, but I really can't comprehend what exactly you are asking, nor can I visualize your box in order to help you.

okay lol sorry about that I was typing it on a ipad, now im on a computer. Now pretty much what Im saying is that my port started of at 4 inches, where it actally goes into the enclosure its only 2.75, what is gonna be the outcome is the tuning just gonna be way of or am I gonna have to see whats gonna happen?

if you wanted a port that's 18.75" long and your port ended up being 2.75" then yes, your tuning will be "way off", qualitatively.

so port is 4" wide, but where the port ends it's only 2.75" from the wall of the box. cut the port shorter so it's got 4" of space. Not worth doing a short "L" at the end of the port IMO. Also if taking into account "end factor" then your port will extend 2" beyond it's physical length, so you should be fine.

In effect, it will actually be an L port since you stop the port width from the back wall.

Those are the answers you needed. This will definitely help the port reach its potential. Before it was rather choked.
