Backfire sound?

Just got my new M5. Does anybody else have this sound, almost like a small "backfire" when you lift off the accelerator suddenly, and sometimes during an up shifts as the load comes off the engine. Is that normal? Maybe a bit of compressor surge on the turbos?

Everytime I approach a bridge or tunnel I full throttle in first to 7200RPMS just so I can hear that Gunshot.

Sounds even more pronounced with a good exhaust. The pops and crackles are much more enjoyable.
