possible backfire?

A couple of weekends ago I had driven from Azusa down to Irvine (about 45 mins). When I got there, I was letting the car cool down when I heard little popping sounds from the exhaust. Does that mean my car is backfiring? They weren't that loud, but still noticeable (I was sitting in the car, with the door open). All I have is a Cobb SRI. Should I be worried?
 
It's common on these cars, mine popped at idle stock and occasionally while driving, and now with some mods it practically spits flames on upshifts
 
ssm3, have someone take pictures at night. if you have full open exhaust and are still running rich you can get flame from 1,2 shifts if you lift throttle. I hear tell. Little bubbling sounds are ok nokkers. But loud backfires at idle or while on the throttle should be rectified by dealer asap and quickly.
