Most guys love that sound and try to make it louder 
...but you can have a tuner reduce most of it by bumping up the timing in the Coast Down Spark table by 2-3*, from 0 - .4 gm/cyl across all rpms. Any decent tuner can take care of it for you.

My 2009 Z06 had some exhaust popping, etc but when I installed a Vette-Air scoop to get cooler air to the stock air filter & element, while retaining the stock tune, the exhaust popping was almost entirely eliminated.
Why? I have no idea.

Love that sound; we used to work hard to get a little of that "burble"............ Don't back off the gas so much when you shift.
