Buzz after AAM Short Tail install

RonZwanson

So I installed some AAM Shorties just about two weeks ago now. I'm not sold on them yet, for a couple reasons. First of all, none of the videos on YouTube come close to accurately depicting how LOUD these things are. They don't sound bad, just LOUD. I don't know if I can live with it as much as I drive the thing.

My primary gripe is that there's a buzz/plasticy-sounding rattle coming from somewhere around the hatch. I'm wondering if anyone has experienced the same thing after installing new exhaust, particularly the Short Tails. I plan on doing some exploratory surgery whenever it stops being rainy and frigid, but that may not be for a couple more weeks. I noticed the tips of the exhaust basically sit right against the cutout in the bumper. And since the buzz sound is typically when I accelerate with some gusto, I guess that could be it, but based on the sound, I think it may be something in the hatch door.

Anybody have any feedback, or likely places I could search, before I go nuts tearing down my car? Anyone had a similar issue? Any feedback would be appreciated. I did search around, but didn't find anything specific to this. If anyone knows of a helpful thread I'll take that too.
