Update
Took the M2 in today to replace the MPE. They gave me a 440i gran tour, it was nice, I did like the new digital instrument cluster. What difference and the exhaust note sounds different. The car pops on start up. Very happy .

Great!! So the new MPE you just received has no rattle at cold start? All the problems are fixed?

Hi all,
I also have the LCI and have had the updated MPE installed two days ago, and can confirm that the rattle on cold start is still there. Although not as obvious and shorter when I don't start the the car with flaps open in Track mode. Off topic, and only get the drone in Track mode. In Sport and Sport+ with flaps closed, zero drone. |

Had mine installed last week and have exactly the same as the above.
I'm not convinced it's a faulty exhaust as it only does it for the first 10 - 15 secs on cold start up, at no other time does it make that slight metallic noise. It just sounds like it's too close to a heat shield or something, but I've not been under the car to see the design or what components are around the exhaust route. I'm guessing there's been no acknowledgement from BMW or a fix? |

I had the latest slide on version fitted at the weekend just past and I get the same vibration on cold start then it goes.
I can live with that and even the droning but what I’m finding is in comfort and valves closed the drone is slightly hurting my ears even after a short journey. In sport/+ with valves open or closed it appears to be fine. Not much use for the long drives I’ve got with work at times so a bit disappointed after I decided on this for ease of purchase over importing and being stung at customs. For anyone who has had the resonator spliced in, I’m assuming with the latest version of MPE that it won’t be possible to have it positioned in the oem position without cutting into the MPE itself - which is a no go considering the slip on design? Edit: I also appear to be smelling more fumes - not normal I assume? |

I just think it must be the way each exhaust is fitted. There might be a slight different bend on a hanger or a small difference somewhere else, like on the tailpipes. There are far too many doing it for it to be a faulty exhaust - that said there's nothing stopping people going to their dealership and trying to get a different one, hoping to get lucky. We'll see if I can live with mine. The dealership isn't exactly local so I have to weigh everything up. I've noticed a small blip of the throttle when it starts seems to helps sometimes. Glad you got sorted |

I guess I feel lucky that I have no problems. My MPE was port installed.

Yeah I have now spoken to the dealer and missed a call after work to arrange did me to go in. I’m hopeful they remove metallic noise which I’m not too fussed about tbh. It’s more the fact of having to cut into the MPE in order to place the resonator back in the same spot but needs must! |

Some m2 MPE owners have welded their stock resonators back on trying to mitigate 3k rpm drone... http://f87.bimmerpost.com/forums/sho....php?t=1492606 http://f87.bimmerpost.com/forums/sho...ight=resonator

Yeah I’ve seen that mate but they are not fitting in the original spot so it’s still leaving drone. By the looks of it I need to cut into the MPE itself to get the correct spot so I need to decide if I want to do that or just return to oem.
On another note I think they have nicked something and there is some sort of leak near the centre of the car behind the front wheels. Not going well! |

The noise you only hear at start-up is the exhaust pipe rubbing against a bracket about the middle of the car. The shaking is the same it's been since 2016, it is a result of the design.
On a side note, I now have approx. 30 track days on my M2. The MPE is a good big louder now than when new. I believe the packing starting to get some wear, sounds awesome! |
