Yes it will do that especially if you have the db killer out.

Air gets sucked down the exhaust or maybe you have a tiny leak in the header. Just keep the throttle shut on overrun or learn to luuurve the pops.

All my Gs's (2006, 09, 12) have popped on the overrun but with the standard exhausts - I love it. All should be ok - I assume it's not violent and you haven't blown the end off the can?!

My new (to me) 2012TC has always gently popped and burbled on the overrun (standard exhaust).
As posted above, if yours is more violent bangs rather than subdued popping then it's probably an air leak in the exhaust - check all the joints and reseal as necessary. That said, my old 1100 with standard exhaust used to catch me out every now and again and do a proper bang when throttling off from highish revs. Frightened the bejesus out of the missus
