It is a bypass plug that goes in the existing single harness that tells the DME that the flaps are no longer installed. The MPE functions independent from the DME and activated via the BT transmitter you keep in the car.

Yes there is a plug on the harness that fits in the hole....at the time it would not stay in place since the harness is a bit stout and the temps were cold. I put some RTV on it then re-inserted to keep it in place. Then reshaped the heat shielding so it did not smash the wires.....I am a bit OCD with some things to prevent future problems Last edited by horsepower_and_hounds; 01-07-2018 at 08:47 AM.. |

1st is the old style clamp that does say 38nm...it is for the version that butted the pipes to each other then used the wide band clamp. The 2nd is the current design that the pipe slides over the stock pipe at the cut. The doc states to torque to 55nm. It is the same as the ones (pictured) they use on the F80/82 MPE

Also, do you happen to have the part number for the new clamp? My dealer fixed the cold start rattle to some extent but there is still a tiny bit left. I would rather have them fix it with the new clamp. Not sure if it can be done to an existing cut in the exhaust as the new one is supposed to slide over. Thanks in advance! |

Is the bulge near the top a secondary resonator?
Looks like when the MPE valves are open some exhaust can still flow through the resonator. Is that for drone suppression? Does MPE drone? |

The bulge at the top is the mid pipe resonator. And yes the MPE drones without it.... here is the original pic before someone photoshopped it

You know I have to comment.....today I drove around the Charlotte outer loop and did some pulls, shifts hards runs and cruise in both comfort, sport & sport plus with flaps open and closed. I have a JB4 so it has a bit more pep. It does exhibit drone around 3k and you can hear it and feel it in your butt but in defense of the MPE...... how much damn time do you spend at 3k? The drone window is not that big and at 80mph in 7th (dct) your way below 3k so their is really no drone then and our cars are built with less sound deadening material so everything seems to cause more noise.
I think it sounds really really good and find that it is fairly quiet in the flaps closed mode aka sport. I think it gets a bit of a bad rap...I am really glad I got it and very happy with it. |

That is good news I bought my MPE today from my local dealer, its coming next Friday, I asked the dealer to cut the stock resonator to add it in case I need it and they said no problem. Ill keep it in case its a drone. They said this is the last version of the MPE and they fixed the drone and vibration from the first Version. Well see.

I have the carbon wrapped titanium exhaust tips and not sure that don't add to the vibration sound. My MPE on the F82 vibrated like crazy on cold start...thought it was the titanium. Now have a stainless MPE in the F87 and it vibrates also..... cold start sux

QUOTE by isjoey Correct. My MPE was port installed also. Sounds like there have been issues with some port installs. The clamp that connects the OEM cut pipe to the MPE pipe just before the bracket. My rattle was caused by the exhaust pipe backing out from the clamp and causing quite a bit of sag, and it eventually got so bad to where the exhaust pipe sagged and caused contact with one of the center chassis braces... made for a nasty "rattle" on cold start. It seems like they over torqued the clamp causing it to oval a bit and thus not get a solid bite. I've pushed in my exhaust quite a bit and re-clamped the exhaust. 150+ miles with 0 rattles, it puuuuurs on cold start now. My tips are all the way in, and both sides are much more even now!
