G21 M340i w/ Panoramic roof exhaust options
Took delivery of a Marina Bay Blue M340i Touring this Friday coming from a M4 (pre-OPF).
While the M340i Touring is great in terms of usability compared to the M4, also performancewise, the sound is just dramatic, it’s so quiet! I’ve been looking at various exhausts as a replacement. But I cannot find aftermarket exhausts for the G21 with the panoramic roof? All manufacturers state they’re not compatible with the panoramic roof option? How does that work? Anyone know more about this? |

Hi, mine is a G21 touring with pano roof and fresh back from Milltek after having the exhaust developed. It’s the same system as the G20 but you have to ensure it’s one specified for the Pano roof. Basically the pano roof one will fit all
Versions whereas a system developed for the non pano roof won’t fit as it hits the under car cross bracing. |

Look forward to hearing some sound clips of the milltek, I have a M340i touring coming and improving the noise is a priority, although don't want anything too loud.
Also pics of the Marina Bay Blue please! |

The G21 with panoramic roof has extra reinforcement bars under the car apparently, going over the midpipe.
AC Schnitzer have just updated their exhaust to be compatible with this as well and I’m getting it fitted on 17 November! |

Not the best pics. Needs to be very sunny and the car needs to be clean for the best pictures.

Hi the original Milltek exhaust was made on a non pano roof g20. They tried to fit the same system on my car and it’s very different. After a week of development they made a new system on mine last week and this will now be the master standard. It now fits both pano and non pano roof models. EC approval coming and sounds great in sport.
My cars going back now unfortunately so will be taking the Milltek off and putting the standard back on. 😢 |

I think I recently bought your ex-car! MMB is great, although at first we thought it was San Marino. We found the ACS exhaust "gutachten" in the glove compartiment, too bad the original exhaust was put on |
