At idle and under normal driving conditions, the Porsche Cayenne exhibits an almost inaudible idle, but romp the throttle and the burble turns into a hearty growl. The exhaust makes its way to the rear through a twin-chamber exhaust with one three-way metal-based catalytic converter on either side exiting the rear through highly styled and sturdy dual exhaust tips. A set of tips decorate each side of the Cayenne's rear view.
