It's not good for your exhaust valves either from the timing being retarded so far. There is actually a good reason as to why high performance engines do exhibit SOME pops and bangs on shifts and coming off the throttle. But any more after a moment or two once the throttle body shuts is poor tuning or your car isn't up to temp yet.
