The Flowmaster Sound is the true tone of American muscle and performance. Available in a wide range of domestic and import applications for automobiles and trucks. Flowmaster mufflers produce more power than OEM and competitive aftermarket products.
This American Thunder exhaust system is the loudest in the Flowmaster Exhaust System Line-up. This American Thunder exhaust system has been individually engineered and dyno tested with the latest in technology. Through this technology you will experience improvements in acceleration, passing power, and fuel mileage. The key to the systemís 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 resistance so your system will last. The American Thunder system comes with a two-chamber muffler that will give you plenty of aggressive 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.
