Vibration under load in chassis and pedals

[johnnydg]

Hi all, I have a vibration under load in the chassis and pedal and shifter. Nothing really in the steering wheel. I just put my OEM exhaust back on except for the axle back Eisenmann race exhaust. Nothing is touching anywhere under the car. I have been working on this for weeks and thought it was an exhaust issue, now with the OEM exhaust back on what else could this be?

Also, when I put my clutch in, the vibration for the most part goes away. Then when I release the clutch it comes back. I assumed this had to do with exhaust pressure causing a vibration in the chassis but obviously that isn't it.

This is on my 2011 e92 m3 supercharged with 37k miles, and only does it while I am moving, not at idle

A friend suggested the Guibo joint/flex joint and transmission mounts. And to check the driveshaft?

Based on the symptoms could it be the throw out bearing?
