speedART's 987 exhaust system releases the classic flat-6 sound of the 3.4L Cayman engine. This system is an export only version and does not have a TÜV approval.
While optically similar to the TÜV version, it has different packing material to allow higher sound levels. The single-shell stainless steel unit design allowed speedART to develop a richer sound and more power than twin-can designs. Weight is reduced to 28lbs, much lighter than the 41lb factory system. The tubing over the rear axle eliminate the cats built into the muffler but still functions properly so that there are no Check Engine Lights. This system has been measured on a dyno to make 11hp to the wheels, without any modifications required to the ECU.
