Can anyone tell me if this thing is 3'in or if it needs to be ported to be a true 3'in piece. Thanks guys.

You gotta search buddy it's fairly common knowledge that it's 2.5 inches, and no it cannot be ported 3 inches it's physically just not large enough to port it to 3 inches, here is a megan for reference VVVVV

And as you can see the invidia isn't really a full true 3 inches, but it's close. VVVVVV

Good info. Is the Invidia portable?

The invidia can't really be ported to make it larger, but there is a lip inside where it transitions to the outlet that can be ported or, ground down for a smoother exhaust flow, I dislike the invidia because it has a tendency to shift a lot on the downpipe and leak, the thin copper gasket is not sufficient enough to seal the exhaust, i switched my o2 housing out because of this, a few other people have had this problem, almost all of them leak and need constant adjustment, im sure only a few actually notice the leak, but it does affect your power if not monitored.
