I've got a C7, Z51, exhaust , and it's an automatic. When I'm accelerating hard, just before a shift, there's a pop that is very noticeable. I've tried to go through the gears manually and the same pop just as I'm going into the next gear. I'd like to hear from anyone that has the same sounds I do, or a mechanic that could explain it.
