Kevin, I had a shop install mine when I had my roadster. It seemed to be a pretty straight forward installation, but he did make a small modification to the hanger so it would hang just right. The drone however is still a concern of mine, and why I haven'nt installed a MF system on my coupe.
I'm guessing that would help with leveling the tips, and could also suck the pipe in a little so it doesn't rattle against that cross-brace. I plan to go by an exhaust shop this Friday to see if they'll go for a ride with me, listen to the drone and vibration, and see what they can do to fix it. I also shot an email to Magnaflow describing my issues in case they have some recommendation.
