I have not actually timed it, but it is a good 10 seconds between pops i'd say. It might just be random and not rythmic. it really sounds like expansion of the exhaust, but it's at operating temp. It also seems to make more popping sounds when it's off and cooling. maybe i bound up the collector/cat pipe during the install? Maybe this is just normal with an X pipe and new SS exhaust. I had to loosen both cats from the manifolds to get them to line up with the x-pipe. I can't hear any popping inside the car, just at idle and nothing when accelerating. I'd expect an exhaust leak to be faster, but who knows. I'm going to be installing bbk shorty headers next week so this post is probably mute or maybe i'll be getting more random pops, lol!
