The thing I noticed right away when installing is if the clamps are installed in the wrong orientation (nuts on the passenger side), they are a lot closer to the heat shield. I installed with the nuts on the driver side and physically pushed the exhaust around trying to force contact with the shields to make sure there was enough clearance.
Did you start the car on the lift and check while it's in the air?
Usually things might come look or the clamps get a little undone when driving which is usually why they ask to retighten all clamps again after a good amount of miles
I had some rattling in mine a few weeks after i put it on. it turned out that one of the clamp bolts was touching and rubbing on a part of the heat shield. this was also very random and i couldnt reproduce it by wiggling the exhaust around. I got under the car and saw where it looked like it was really close to the heat shield but not quite touching. I ended up loosening the clamp and turning it some then tightened it down. All was well after that
Good luck with the check up this morning, hopefully you guys find the problem. If not are you reinstalling the stock to to sell the AfE?
Just ordered the vibrant ultra quiet resonator. You should take a look (reviews etc.) I will install it next week. Maybe you can wait to see my result before selling your exhaust.
But if it's so bad can't you send it back? I mean... it has to be something wrong with your exhaust since Afe said they had no such problems before... I mean if thing vibrates in the car, you get head ache because of the drone and you can't talk to the passenger they have to take it back. I would not accept this and if I was foced, I would buy a good microphone for the smartphone and record the sound and show the vibrations...Got back from the shop. Here's where I am now:
-Nothing was loose.
-No leaks.
-One clamp was hitting a bolt that connects to the rear most heat shield. (fixed, clamp rotated)
At this point the car sounds basically the same. My keys still vibrate in the cupholder (albeit a little less, tiny bit less) and the car still drones like crazy from 2.9k to roughly 3.5k.
I've made up my mind at this point. Sucks, because I freaking love the tone of this exhaust. I guess I'm just taking a hit and going back to searching for an exhaust.
Doubt they would mess up on their exhaust. There are only so many made that they take a long process to produce it.
