Flowmaster American Thunder 99-04 Cobra.

These American Thunder exhaust systems have 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 the use of mandrel-bent tubing. The tubing allows for superior exhaust gas flow, while aluminized steel construction allows for its corrosion-resistant qualities. They also feature a 2-chamber muffler(s) that’ll give you plenty of Flowmaster sound outside the vehicle, as well as inside it. Every kit comes complete with all necessary hangers, clamps, and mounting hardware for an easy installation.
