Vibration/Rattle

lmendz71 · 07-18-2016, 05:19 PM

I need help guys 2008 M3 E90 with MPE, roughly 12k miles on my exhaust. I've read MPE is known for cracking but I didn't see anything like that. It's very obvious after I stepped on the gas at idle. I have a video attached. Thank you guys.

I'm not familiar with the MPE exhaust but if it uses clamps I would check if they are loose and tighten them accordingly. Follow along the connecting pipes and mid-pipe and tighten all the clamps. You'll need to put the car on ramps at least to do this.

Almost sounds like it's occasionally hitting the heat shield or something is rattling underneath. May not be the exhaust at all but the resonance from the exhaust

The person doing the filming sounds about as annoyed as my wife would be doing the same.
