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. :tiphat:

I've torn apart my hatch interior multiple times as well trying to figure out what it is. So far I have narrowed it down to the 3rd brake light. It has 2 posts that stick out to align it when you're putting it into the hatch. These posts go through small alignment holes inside the hatch. If it isn't centered (which they never are) they will vibrate as the exhaust goes through the 2-3k resonance band. Major aggravation ensues. :mad:

So far I have installed rubber grommets in the holes to center the posts and prevent them from moving. So far this has prevented the "metallic" sound, but the posts still vibrate. So on to step 2. I have purchased some dense foam that I will try to stick on o the hatch interior trim, and when reinstalling, should brace the posts and prevent their movement, or at least muffle it to when you can't hear them anymore.

I'll be doing this over this weekend so I'll make sure I take video and pictures to help the rest out if it works... :ugh2:

buzzing noise/rattle has been explored to death on this forum if you do some quick search there are a few DYI's to fix it, there are 2 places where it could be comming from, one is the latch for the hatch and one is behind the headliner, in both cases it sounds like it comming from the back because the sound travels down the windshield (that was my case)

its probably behind the headliner, next time you're dirving and you hear the noise put you head in the center of the headliner in the back and push and see if it stops, if it does than you found your source of rattle.

Explain this? Not really able to visualize anything based on that? :ugh2:

There is an electrical plug in the hatch that plugs in to what I guess is the 3rd brake light that is an extremely loose fitting.. That's one of the places I'm going to investigate today. But other then that, I'm not sure. :ugh2:



I know it isn't my headliner as I've never heard anything from that part of the car. :ugh2:

I dont know what could be rattling in the hatch because that is not where my problem was so i didn't have ot fix anything but others did, do some seraches and i'm sure you'll find all the threads on hatch rattling

Do you know what/where it is in the headliner, I'll check there today as well, just not sure what I'm looking for? :confused:

all you have to do is press on the hump part of the headliner hear the rear window, im my case there are plastic push pins that are holding the headliner up, i had to put some tape on them because they were rattling against the metal roof. See the link, towards the bottom there is a pic of the plastic push pin that has a suqare base that is against the metal roof, that will rattle and drive you nuts.

I just went around trying to do something else, and it does Not sound like it's coming from the headliner area. I even pushed on it to see if the clips were loose and it's pretty snug up there... :ugh2:
