The straight pipes and velocity box are what makes the huge difference in sound, with cats in this system sound really nice and pretty loud no drone ,with catless its on another level I get a little drone around 1800-2k rpm but its not that bad the car is well insulated it sounds and feels more like a sports car than a luxury car
