Yup! Pressure side.
It's not restrictive and holds pressure fine. I'm just trying to give you a little friendly advice on this engine. If your charge pipe is holding pressure, you're fine.
But hey, don't take my word for it. I don't know much about these engines.
Your stock pipe isn't leaking boost, and there are literally no flow problems with it at all. The only reason to upgrade it is if it stock doesn't fit your turbo, intake manifold, you add port injection, or you need the bungs for meth or nitrous. You're not restricted there.
Also, the charge...
Not sure what you mean exactly, but the charge pipe doesn't do anything but provide meth bungs, and hold large amounts of boost. ~20ish psi, which is a few more than stock is completely fine on the stock charge pipe.
