It's the engine and or exhaust cooling off. When its hot out, and cars hot you'll notice it more. It's normal for every car. You take a 700-800 deg exhaust with heat shields then cool it off it'll pop and shift etc. Someone else might have a different explanation but that's what I've always assumed it was. It's normal tho, all of my cars do it. Tahoe is louder than the rest, but all do.
