I 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???

I don't like when they are super aggresive but I do like some intermediate ones.

I assume a downpipe will not be enough...

Is there a way?

Secondary downpipes
Remove the Resonator
Install a Valve controller.

This will give you a deeper louder sound and some good burbles.

I dont think the 40i has secondary downpipes.
I already have the valve controller

Unlock your ECU run bootmod3 stage one and you can make the burble from 0 to 12
