Description

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