Is there a way?
Remove the Resonator
Install a Valve controller.
This will give you a deeper louder sound and some good burbles.

MBoriPerf wroteUnlock your ECU run bootmod3 stage one and you can make the burble from 0 to 12I own a 2025 X5 40i with the factory M Sport Exhaust, how can I get a burble tune to hear some "childish" pops and bangs???
