Hey
I recently bought 435xi with some mods
valve exhaust GTP + Downpipe
BMS JB4
intake BMS

and when I accelerate it sounds great but when I let go the paddle the exhaust makse some nice popping sound but its stops after 6-7 pops. I saw some other 435i giving some awesome sounds and popping multiple times not like in my case. I drive in sport and sport+. What can i do to make pops last longer when I stop accelerate?

Higher Octane fuel helps as well, use the best Gas available

Yes, I've noticed exhaust tone is better when I use better quality fuel.

BMW MPPK increases the burbles during overrun conditions. Add the MPE and it will be even more apparent.

I don't have any mount to record during drive but here are some stationary rews

While stationary it makes enough pops. But when I start to drive they disappear ;(

Thanks for the video. Helps to actually hear it.

Sounds pretty much as it should IMO. If you really want more burbles you need to spend more cash. A flash tune will bring them out. BMW offers the MPPK, other aftermarket ones are also available.

Mine pops way more when the temp is below 10degreee Celsius and they are much louder when it's cold. Also drop the back seats down and the mpe is much louder

So even with jb4 i can have mppk flashed by the dealer?
Do you know what kind of other aftermarket flash tune?

And yes, while stationary cars sounds amazing. But as I stray driving it stops
I will try to include video soon

To be safe I'd take the JB4 off before taking it to a dealer to have them install the MPPK. But yes you can use both on the car.

Not real sure what's available for you in Poland as far as flash tunes, perhaps some of the other Europeans here can point you in the right direction. Protuning Freaks (forum sponsor) has something available in Russia and Sweden. Check out their thread here.
