Muffler Advice Please!

[Need_for_speed]

Time to replace the muffler on my 2000 Boxster (non-S, 2.7L). No money left to do the rest of the exhaust system as I just about blew my entire budget on IMS, RMS, clutch, wheel bearings....the list goes on.
But...thanks to a loose baffle, looks like I need a new muffler, and I'd like to do something other than OEM.
Here's the big issue: I live in a community with some pretty strict noise ordinances. I also do a little highway driving from time to time and I don't think my wife and I want to have to scream at each other to be heard on a road trip.
So, in short, looking for something with a pleasing roar when I'm on the throttle, a nice little rumble on idle, and fairly quiet at speed.
Any recommendations?
