Only you can tell if it's loud enough, but the PE produces a great quality tone.
It also gives you options at the mid-pipe.
If you are still running stock mids with secondary cat and resonator, you can take both out or just the resonator or leave both on.
I've heard it can be drone-y with no cats and no resonators.

I'm N55 with stock cat, and PE with Y pipe (res delete, N55 has no secondary cat). I don't get any drone except under predictable transient conditions and the sound is great.
However I find myself now wanting about 20% more volume, so I'm going to go with a catted DP and hope that gives me some volume.

Bottom line is that there are few exhausts that produce a nicer sound than the PE. Yes, I know that's subjective and some would disagree, but there's a reason it's one of the most popular exhausts for this car. YMMV.
