E88 specific exhaust hanger rattle
The E88 has two cross braces that run across the rear of the car. The very tip of an exhaust hanger contacts one of these braces under load, making an obnoxious rattle. A nice half inch of additional clearance would be optimal, im thinking metal washers at a brace mount or exhaust adjustment. Discuss!
Oh exhaust in sig fwiw.

Can you describe this rattle? I have a 2011 135i vert, and I've had a minor rattle since new. It's actually kind of a light clunking noise - sounds like it's coming from the rear, but can't tell for sure. I hear it at low speeds, over any kind of rough pavement. When I go up the ramp in my garage, I definitely hear it. Thanks.

You can space down the bracket (driver's side) with some washers for more clearance, which is what I, and many others, have done after an aftermarket cat-back was installed....much more prominent rattle on the convertibles but that will solve the problem. Also, make sure your tips are not hitting the valence as well, which will require stiffer rubber hangers in the rear so the tips don't move up & down as much.

I used aluminum washers...add a few to bring it down to clear the bracket. And you can wiggle it up & down to be sure you've added enough so you don't have to crawl back under it if it still hits after driving the first time.
