In case anyone doesn’t know, the pop sound can serve a real purpose. The sound comes from extra fuel being ignited in the exhaust, which is done to keep the turbo spinning when you let off the gas. It helps minimize turbo lag. It also occurs in older race cars that had carburetors because they had less precise control over fuel injection compared to modern cars.

That said, some people tune their car to imitate that sound with no purpose just cause they think it sounds cool. They waste extra fuel just to sound like that.
