Exhaust Vibration

1sicke92 · 11-24-2010, 08:49 PM

my aftermarket exhaust causes a vibration in the cabin of the car. it is kind of a buzzing sound, and i know for sure that it is coming from the back seat area. i have a e92 coupe btw. i happens always from a stop when taking off. i can't pin-point exactly where it's coming from. anyways, have any of you guys experienced anything like this? if so what can remedy this issue?

Its called "Exhaust Drone" and its often with aftermarket exhausts...

There's alot of threads about it on the forum. Check them out.

Stuff a towel in the ashtray area and also one in the center console and your vibrations will be gone...

A buddy of mine had a rattle at one of the rear hangers on his exhaust. Make sure the hanger isn't touching the body or anything else.

A towel in the little storage department between the two back seats helped for me.
