Flowmaster American Thunder Exhaust Systems

Flowmaster American Thunder exhaust systems are designed with the latest exhaust technology available--resulting in improved acceleration, passing power, and fuel mileage. A key to these performance upgrades is Flowmaster's use of mandrel-bent tubing, which allows superior exhaust gas flow. The systems also feature mufflers (single or dual) that deliver plenty of the rich Flowmaster sound you expect. Components are built from stainless steel or aluminized steel; and some models include tips. American Thunder exhausts are available in more than a hundred configurations for fitment on specific truck and car applications.
