What about EAS? They're a great supporter of this forum, and while I've yet to stop by, many people on the forum speak highly of their work.
I've had work done at Supreme Power (stubborn side gill install) and Status Autowork (Eisenmann Sport exhaust, matte black M3 emblem), and I was very happy with the end result of both. I was especially impressed with the level of service I received at Status. They drove my OEM exhaust back to my house in their shuttle Prius, instead of having me load it back up in my trunk. I certainly plan to give them more of my business in the future.
