sorry but i been reading lot of mixed answers about the exhaust situation.
I order my 21 M340 and it should be here by December cuz I was not in a rush to get it right away. so does this also affect the North America Market with exhaust? also when you build your own vehicle i do not see option to add the M performance exhaust. Does it mean North America market get it standard M performance exhaust? please answer only if u are in USA and have one 21 m340 thank you |

Other threads on this forum have positive things to say when it comes to pop/burbles with the MPE installed. https://g20.bimmerpost.com/forums/sh....php?t=1769210 |

For my 2-cents I don't think the MPE exhaust is going deliver the 2020 pops/burbles people are after here. The pops/burbles are really a function of engine tuning and not the exhaust.
Also the stock M340 exhaust is already dual piped from the downpipe back and is non-resonated. The MPE "exhaust" (unlike on the 340 F30 - which eliminated the two resonators) is really just a muffler. And a muffler alone is not going to give you pops/burbles. You will get a more aggressive exhaust note and it will be louder for sure - but an MPE muffler is not going to change a 2021 into sounding like a early 2020 car. Only a flash tune will do that. Don't get my wrong I think the MPE muffler is wonderful and delivers a nice tone - just don't think it is the solution to missing pops/burbles if that's what you are after. |

Can confirm my 2021 with the hybrid system has virtually no loud pops or burbles. Only on sport plus second gear after I rev it hard up to 3k rpm I can hear 1 or 2 pops but not loud. Downshifting gets 0 pops. Very disappointing.

There seems to be no consistency amongst the 21 MY vehicles in the US. Maybe they'll be an answer soon if enough people reach out to BMW NA.
Mine pops and bangs and sounds like gun shots sometimes on downshifts w the Dinan. But the exhaust note even without the burbles sounds really good IMO. Not a total loss at least

I will just wait and hear the original and worst case I will just buy it and do it my self if I want to upgrade since everyone has different thoughts and opinions about this. it's crazy that no one has a video and compare the m340 stock and m performance. but everyone has a saying of it just my opinion

As for the pops and bangs, this has nothing to do with the exhaust other than being louder. This is something that the car has to be tuned for. Looks like they no longer tune it the same as the 2020s. |

I know for a fact there were zero build slots left when I ordered, my dealer managed to get a spare individual build slot from another dealer and was surprised the factory didn't cancel it. |
