If you're willing to spend the money, the BMW PE is a good bet. It's sporty, but not loud. It won't intrude into the cabin with the windows up.
If you want a louder exhaust the PE likely won't be enough.
Since you're in FL, you may want to check out the Active Autowerke exhaust. They're in Miami. If you're up for a road trip, they're probably your best bet for a quality install.
