burble and pop on m50i

Hi guys, does anyone know how to create pops and cracks on the 21 x6m50i? The car has some good cracks and pops during revs on sport plus. However, I do not hear any during the drive.

On the gle53 I noticed I could get pops and cracks by accelerating to a high rpm and just press the brake a little. I tried the same on x6m50i which is a v8(praise on bmw) compared to a straight 6 on the gle53 but it didn't work. Is there something I should try?

I am also thinking of tuning the car to create more obvious burbles as I do enjoy the sound. However I am just worried of it voiding the warranty.

Any suggestions would be highly appreciated!

Thank you!

sick! what color is that?

BTW I have experimented with setting the engine sound into sporty and putting on sport plus. I would press the gas relatively hard to 3000rpm and upon release I can hear the pops but not very loud. Then if I keep tapping the gas I would also hear it. It is not loud tho. I will change to a catless downpipe in hope to fix that. I hope people can provide easier ways for the pop to occur so I don't have to excessively tap the gas.

I don't know if it applies to the G05, but on my F90 M5C, you had to be in sports plus with the exhaust setting on (the latter is not a function on the G05) and then you would hear pops and burbles between 2500-4500rpm upon deceleration, and possibly only from 2-4th gear.

So if I was cruising slow in 2nd gear, and at 4400rpm lifted off the gas, it would pop/burble instantly, every time.

I don't know if the G05 has similar parameters that must be met, but I'm betting that being in Sports or Sports Plus is probably one of them.

New Exhaust or potentially modify it. . . see below post.
Many people don't like the overly stimulated AMG - sounds like it's trying to hard to stroke egos. It's a fine balance between sounding mean vs. cheesy.
Resonator delate below - sounds like a good balance

Burbles and pops need to be coded into the ECU. I've already asked my tuner about it. They can do it, but do not recommend it on a car that has factory catalytic converters.

Noise regulations have caused many manufacturers to make their cars quieter, compared to (essentially) the same car from a few years earlier.
