Loud Backfire sound from Sebring Z4 xos

[Valor]

Hi all, I'll be sending the z4 to the tuners shortly for regular servicing and coilovers so before that I just want to check if this loud backfire (sounds quite good like thunder actually lol) from a sebring xos is normal, as in the sound made after releasing the gas pedal is normal for this brand. Noticable only if top is down.

Thanks!

Wah lou why go off topic so fast lol.. seriously I think backfire is not too healthy for the car in long run something like not enuff combustion for the fuel or fuel mixture too rich or something right, aiya nvm I go ask WS.

Ok where's the BBQ..

It's normal.

Even on the stock Z4 you will hear backfire, just not as pronounced.
