Flowmaster 04-08 5.4L F-150 American Thunder Dual Exit CatBack


These American Thunder Flowmaster 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 Flowmaster's use of mandrel-bent tubing. The tubing allows for superior exhaust gas flow, while the aluminized steel construction allows for its corrosion-resistant qualities. These Flowmaster American Thunder exhaust systems also feature a muffler(s) that'll give you plenty of Flowmaster sound.
