Depending on the tune/tuner, it can be a “burble” or straight gunshot pop. Duration is also customizable. My N55 with Mission Performance tune will “burble for about 1-1.5 seconds and I love it. The “sounds like a drive-by is taking place” is a little much and brings up flashbacks from my neighborhood as a kid.
