Software Update Killed Exhaust Sound?

I recently had my first scheduled maintenance on my 2011 35is.
The oil was changed and there was a software update.
The car seems to great in terms of power and handling, but the exhaust has been tamed! Lost is the nice pop between gears and new is a low gurgle when idling. I've driven it hard all weekend hoping that might spring it back to life, but not yet.
There was a post a while back that mentioned the same issue ( and the idea seemed to be it takes a while to get the old sounds back. Any one experience that?

First post by the way, and you all have been a big help with insights and questions. Thanks for that too.
