F10 M5 gear change exhaust crack

[V5Ade]

Occasionally I've noticed a loud crack from the exhaust while changing up in manual mode, it's normally 2nd to 3rd. It does not do it every time.

Does anyone know what the conditions or parameters that cause this to happen? There are times when I don't want this to happen, and then there are those times when you're going through a tunnel

I've never yet been able to replicate this on demand as seems to happen at varying points through the rev range & not in ever gear.

That's my experience also. I've just been out for a run, not once did I get the 'crack'.
I'd love to know how to replicate it on demand.

Mode 3 gearchange and sport plus throttle. The hard one is getting the backfire when lifting off sharply in 3rd gear.

Is that in manual or automatic?
