Which mode are you talking about. Comfort with flaps closed? Even in this mode I have some drone, with ASD off. |

I have the MPE with ASD off and the drone is definitely there in Sport / Sport + with valve open. Only time it is livable, is with valves closed in comfort. |

TBH - retrofitting the stock resonator into MPE piping - at a different location than the stock exhaust system - will do very little to fix drone.
Resonance - that causes drone - occurs at specific frequencies. Resonator(s) is/are added at particular location(s) to counter these rogue resonance(s).

Always sport. Valve open or closed doesn't seem to matter. I usually drive with valve closed. My MPE was port installed if that matters. |

Certainly I don't notice much drone in sport/sport+ flaps open. Comfort is terrible ASD on flaps open. |

The only time I drive with valve closed is on early morning cold start up, as I live in gated estate and would wake the entire community. Lol. |

As am also an old git at 57 and the drone is terrible. Prior to this I had the 1M with the Meisterschaft exhaust with much less drone. Go figure. |

I have MPE with the stock resonator and it does still drone at around 3k RPM. I have the ASD bypass harness. ASD was very annoying but I dont mind the drone at all. Drone is louder with valves open but I still prefer driving with them open. I'm really happy a fellow forum member was kind enough to sell me the exhaust. It's made me love the car even more

People with the M6 suffer more because with DCT you can cruise at highway speeds in 7th gear.
I'm gonna look into adding an aftermarket resonator and I'll probably try to wedge it in as far to the front as possible. If the car becomes too quiet I'll add catted downpipe. |

Drone does diminish slightly in any case as the pipes become carbonated |

DP is whats missing. DP with stock catback is better sounding than catback with stock DP, and you definitely get more benefit in the cabin.

Definitely before jumping into either getting a DP or exhaust - will want to have a listen to as many options as I can. I find exhaust and anything car sound related is very very subjective. I really like the MPE though. I test drove an OG with the MPE for about 25 mins and that was great but I was probably too distracted with assessing other aspects of the car than just focusing on the exhaust. But it could have exactly just been that - fun for a quick squirt around the block and not something so suitable for daily or longer drive use. |
