Default Exhaust pop

Has anyone with aftermarket mufflers experienced a pop at deceleration from 2-1 gears? Recently I’ve been hearing almost a crackle pop with my stock Rcf mufflers on my rc350

There have been pops on deceleration in any gear with the GReddy exhaust, which is expected. During deceleration, unburnt fuel is detonated in the exhaust.
