Ford: 1999-2001 4.6L, SOHC Mustang GT, 2 1/2 in. dual rear exit, polished stainless steel tailpipes, Force III, cat-back exhaust system

This Force II exhaust system has been designed with the latest exhaust technology available. Through this technology, you will experience improvements in acceleration, passing power, and fuel mileage. The key to these performance improvements is through the use of mandrel-bent tubing that allows for superior exhaust gas flow. Aluminized steel tubing has been used for its corrosion resistant quality so your system will last. The Force II system comes with a three chamber muffler(s) that will give you plenty of Flowmaster sound under hard acceleration but low sound levels while cruising. Kits include all hangers, clamps, and mounting hardware for an easy installation.
