Also try this.

Let off in 4th, don't touch the accelerator Dan then let off in 3rd and then into 2nd. Make sure the revs don't exceed 4k and don't drop below 2k. I can usually get a gun shot doing this.

Guys, regarding burbles/cracks/gunshots

Check my thread out and give that method a try.

This will also not work many times in rapid succession, I think they've implemented some kind of cooldown period before it starts to pop again. I know this sucks, but there's nothing you can do about it really.

I made a thread about this issue and it seems like this is exactly what's happening with mine. I wonder if BMW service would revert this. Besides liking the car the exhaust is what sold me on it when I purchased ir.
