While I'm running a CG-Precision DS1 catted I am a big fan of the AA catted DP. Are you running through the stock or MPerformance muffler? For me I'm really happy with the sound and tone through my stock muffler but from time to time I am tempted to pick up the MPerformance
Congrats! Looking forward to your feedback |

MP exhaust is nice but just a bit too loud for my taste.

Do you have to get a tune to operate with an aftermarket downpipe?
Will installing an aftermarket downpipe cause CEL? Will installing an aftermarket downpipe catch flack from the dealer at service intervals? |

I'm running the AA catted DP in my JB4 '21 M340 with no issues. I get my car serviced at a local euro shop, so I can't speak with certainty for the dealer experience, but I would assume the worst-case situation is them making a note of it in your car's file. |

From what I've read, often DP's will throw a CEL. This catted option from Active Autowerke will not. And you likely pay more $$ because of it. As for the dealer.. I'd assume if you had an issue with you exhaust or turbo, they have reason to deny a warranty claim if they wanted.

Too much probably, around $500. Taking it to a reputable BMW race shop in the area.

The AA downpipe has an EPA-certified GESI cat. Since it's higher quality, it does a better job "cleaning" the exhaust gasses and will not trigger your O2 sensor. |

I'm not too familiar with the Akrapovic product since few people here have bought it, but the AA downpipe is guaranteed to not cause a CEL while Akrapovic suggests using an ECU tune to avoid a CEL. The AA cat is 400CPSI while the Akra is 300CPSI.

I've had no droning in either mode, but my experience in comfort is limited since I almost always drive in sport+ |

My 2021 M340i is very quiet and has no burbles/pops like the 2020 because of both the software tuning as well as the mild hybrid system, right? Does this mean that when it will be possible to get an ECU tune on the 2021, the stock exhaust can sound like 2020 models or even better? |

As an example my Mission Performance flash is the same whether it is stage 1 or stage 2 however I can change that. In my case both stage 1 and 2 are quiet and tame in eco and comfort and far more unhinged in Sport and Sport+.....but this is by design by MP. Very stock like in comfort very pronounced pops burbles and bangs in Sport and Sport+ It can also be set to be almost as quiet as a 21 while running Stage 2 in Sport, Sport+ |
