All Flowmaster exhaust systems give the same improvement of performance. All Flowmaster exhaust systems produce a beautiful deep performance tone. Choosing between the five different exhaust systems is not a technical decision – it is all up to your personal taste. It’s A Sound Decision™. The racing origin is evident in every Flowmaster exhaust system. All the five series of systems are tuned for maximum performance. They differ in technology and tuning, and thus in tone and character, giving you a performance engine sound to your personal liking.
Flowmaster exhaust systems employ two unique technologies, the patented Delta Flow and the Laminar Flow. They give different characters of sound and can be tuned to achieve the desired exhaust note. Flowmaster Exhaust System Technology is so versatile and gives such a high degree of control that it is used both by racers, who want maximum power, and by the U.S. Air Force in Stealth applications, where maximum silence and minimum heat emissions are prime considerations.
Be it for a domestic or import truck, SUV, off-road warrior, daily driver, muscle car, euro-spec cruiser or sport compact vehicle, Flowmaster technicians personally hand select the right muffler, tubing size, resonator, and tip to make the process easy for you. Best of all, Flowmaster stainless steel exhaust systems are covered by a Limited Lifetime Warranty; ensuring that your exhaust will last as long as you own your vehicle. If you choose aluminized steel products, Flowmaster backs them up with a 3-year warranty.702.73 943.89
Brand: Flowmaster Part Numbers:
Flowmaster® has its roots in solving the engine noise problems encountered by California racers in the 1980s. In 1983 Flowmaster’s founder, Ray Flugger, created his first patented design of racing silencers, which dampened noise with minimal loss of power. Ray attached handles to ease carrying the square shaped race mufflers through the race pits, and the mufflers became known as the "suitcase mufflers." Today, the innovative Flowmaster mufflers are the result of years of development with top race engine builders, thousands of hours of dyno research and "real-world" on-track testing.Flowmaster® - American Thunder™ Stainless Steel Cat-Back Exhaust System - Dual Rear Exit Reviews (2)

I purchased the American thunder exhaust kit for my 2011 Inaugural Challenger 6.4 HEMI. I took the car to local exhaust shop dropped it off at 8 am. They called me shortly saying it was done and sounded great total installation $105.00 and fit perfectly. I went to pick up car and the staff followed me out to hear it again. I used my remote start and from the first fire knew this was the sound I wanted. It has a very deep aggressive sound. Getting on it going down the road turns every head and sounds like a race car. Very happy with the exhaust! I don't really like the exhaust tips but will be painting the inside black. Just is new and can see the welds.Was this review helpful for you?
