Tailpipes were now turned down as the new bumper cover eliminated the tailpipe extensions. Exhaust tailpipes of all S-Class variants were visibly integrated into the rear bumper. Nonpoint source air pollution affects air quality from sources such as smokestacks or car tailpipes. At the rear, the vehicle has rectangular tailpipes integrated in the bumper. The album, "Headlights & Tailpipes", was recorded in Toronto, Nashville and Texas. The tailpipes were somewhat unusual, the nozzles being separated by the aircraft's fin. Because of the lowered booms/tailpipes the lower, fixed horizontal tail was removed.
