i wouldnt make that a reason not to take delivery of the car since there are many ways to change the sound. the car is still custom and 1 of 1 built the way you exactly wanted it. and dont forget it stills an M340i

People complained about the F80 sound, IMO, it sounded 20x better (maybe too loud?) inside the cabin. I don't see anything special about the stock M340i exhaust sound: https://g20.bimmerpost.com/forums/sh...16&postcount=1 |

I just got back from a test drive with a 21 model year and it definitely sounds different. Virtually no pops or burbles on downshift and it really disappointed me. I drove a 20 M340i and it was one of the things that sold me on the car. I am not saying it will stop me from purchasing but it has me considering a used M5 more now that they have changed the sound.

I remember my friends and I used to attach playing cards to our bicycle frame by the tire, so that we got 'pops and burbles" as the wheel turned and the cards flapped against the wheel spokes. This was Child Pre-BMW Syndrome. lol

Maybe they really want you to purchase the M Performance exhaust to get these sounds?

New to the forum here. I picked up a 21 M340 in the beginning of October and I can confirm I dont have pops or burbles. When driving in sport plus the exhaust seems like it wants to pop but doesnt. I have almost 2k miles on it so far. I went back to the dealer and asked one of the sales guys and he also confirmed that the 21s dont have it. Bit frustrating if you ask me, I love pops and burbles as long as its not overly obnoxious and somewhat controllable. On my Alfa Romeo, my tune allowed me to control it by letting off the throttle and slightly pressing it again. The M performance exhaust models do pop and bang but thats to be expected with a performance exist. Anyone running straight pops that shoot flames? 🔥

Took delivery of a 2019/2020 M340i two weeks ago, apparently almost if not the last one out of the Munich factory before mild hybrid switch over. Only got it because someone gave up their individual build slot to me so feeling lucky.
This thing snaps crackles and pops on *all* downshifts, even sometimes in comfort mode. Pops loudly on startup in all modes. I read somewhere BMW got in trouble for the pops in this and dialed them back, just a rumour though. |

fairly certain this is factory tuning and it doesn't help that the factory DME is now locked and you can't simply flash and unlock burbles

Seems to be a mixed bag, much like the MY20 complaints.

A couple hundred miles on my MY21 M340i and I can confirm that there are no pops and bangs or what so ever, no matter which mode you're in. The car is still considered to be loud in sport plus, but all you could hear is the sound of the engine at higher rpm.
If you go to YouTube and watch any review for the 2021 models, you'll notice a significantly less amount of reviewers mentioned the exhaust note, and they tend to only rev it up once or simply not to rev it at all; whereas for the 2020 model, the stock exhaust had almost became the car's biggest selling point and no one could review the M340i without revving the car to hear the pops and crackles. To me this isn't that big of a deal as I intended to use this as a daily and the 48V mild hybrid system does noticeably improve the overall smoothness of the vehicle which is a pros > cons for me. But still, lacking that sensational aspect is bit disappointing and I feel bad for those who weighed in the exhaust note when they made the purchasing decision. BMW should definitely address this issue when they rolled out the revised MY21 as almost all of us test drove the 2020 model before pulling the trigger. |

Been lurking for a while, have an M340i xDrive on order (almost impossible to find in South Africa with the covid-19 supply disruptions and our market being pretty much immaterial).
Does anyone definitively know when Munich switched over to the 48V MHEV models produced in Germany - am hearing conflicting reports it was August but some are saying only from November ? I believe Mexico switched over some time ago so NA models have the hybrid tech. My build week was 2020 09 40 (so am guessing very end of September) and VIN starts with WBA as all our models come from Germany/Bremerhaven port of exit. It seems to be a case of MY21 without 48V and without OPF (no OPF for our market) gets the superlative exhaust note with burbles, while MY21 with the switch over does not but benefits from eBoost and much smoother ASS. Local dealer seems clueless. |
