dang it! wish this was found out earlier. I replaced my AA with a PE cause of the drone. Loved the sound of the AA better (minus the drone at 2k). Now I'm down a few hundred bucks with an exhuast laying around when all i needed was some cheap wine.

AA sent metal hangers with my exhaust but my installer didn't use them. I'm guessing those would have gotten rid of the drone. I'm sure AA uses them on all their installs.
