Maybe I should also add that I start and drive solely in Sport+ (when manually driving). Perhaps the various remappings in Sport+ (throttle response, transmission gear choice, etc.) hide any variation due to this.

Everything other than the fuse requires getting under car, a small socket set, and small pliers. I don't believe anyone has yet found a coding to keep the flap open, Bimmerlink rather only gives you control to open it when and ONLY WHILE the engine is running.

Hi everyone, new here and using this as my first post to gain full access.
Just in the throws of purchasing a demo M50i so lots of bells and whistles. I am coming out of a Panamera Turbo S which is just amazing but it has to go as I'm soon to be a granddad and need the room. Anyway, the most amazing thing about the Panamera is it's sound, OMG the pops and crackles are to die for. So I started researching the M50i and soon came across a lot of comments saying its sound could be so much better. I was reading with interest the lengths you guys have gone to to achieve a better sound, pulling fuses at certain speeds, love it lol. I haven't seen a mention of what I came across and wondered if it was of interest. Many different versions covered including the M50i but I've linked it in the 40i version here https://www.leib-engineering.de/leib...rive40i-g05-en |

So I tried doing pulling fuse while driving thing with my brother, he was doing 2nd gear sport mode around 6000rpm i pulled it out, and tbh the difference is not huge, the startup is similar, except in comfort mode now slightly more throaty or louder like its in sport mode, while sport mode sound same, so basically I put fuse back as i feel like the gains are minimal doing it in my 50i, at least with putting it back i get the quiet exhaust when i want it...... any other experiences? Maybe it wasnt fully open for me when i pulled it?

I have used Bimmerlink app and fuse trick and it works nicely.
There is a comparison video I made Only thing just worrying is when having flaps open the car generated a huge amount of heat. When I open the door even after just casual drive the heat just hits me from underneath the car which never happens on stock settings.

Usually Adaptive, done testing the same day with stock settings and yes is massive difference with a heat generated. I will test more but if continues probably I will close the flaps for a sake of the car.

So after deciding the flap hack is pointless in 50i model i got to try other things and I found something interesting not sure if im imagining or it does work, basically if you put it in sport individual and set everything comfort, even at 1K rpm you will hear more bassful sound from exhaust compared to comfort once you hit little of gas or drive normally.....
Keep switching between the 2 and hear the difference (keep in mind I think 50i flaps open easier than 40i models, so might not work in 40i) anyway i found it interesting thing despite engine and trasmission in comfort! |

After playing with Bimmerlink opening and closing the exhaust flap, I decided to do this mod today on my 40i. I like the additional rumble and bass that you get on startup and low speed.
Next step is to install my downpipe. |

Is this exhaust flap opening applicable only with the factory installed M Sport Exhaust (or maybe just without it?) or is it worthwhile in both cases?
I have just bought a 40i (almost but not quite new) and the only thing missing from my wishlist is the M Sport Exhaust. Just to be clear, it’s the European version. |

Recently took the car in for service. I left the fuse out. Can’t tell if the flap is open after the service. Should I put the fuse back on and redo the trick again of pulling it out while driving?

Pulled the fuse at WOT Sport+ M2. How do I know the flap is open? Not a noticeable difference in sound, and can´t see the flap since the exhaust is curved. Anyone knows?

Non-Poor Man’s Exhaust Flap Mod
You don’t have to worry about playing with fuses or unconnecting wires. Just get the BimmerLink app and an obdII connector. Push a button and you’re done!

After cold start is done, you should feel the exhaust gases coming out of both tips instead of just one.
