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.613.14Brand: Flowmaster Part Number: 817483 UPC: 700042023684
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.Product Reviews (3)Flowmaster® 817483 - American Thunder™ Stainless Steel Dual Axle-Back Exhaust System (Dual Rear Exit)Average Rating: 5 of 5APPEARANCEEASE OF INSTALLATIONPRICE/VALUEQUALITY(5)APPEARANCEEASE OF INSTALLATIONPRICE/VALUEQUALITY2012 Chevy Camaro | Posted by Paul | (Warrington, PA)

I wanted to make my 2013 Camaro sound a little meaner than the factory exhaust, but knew nothing about exhaust systems. My other concern was that I have a V6 instead of a 8 cyl. and wasn't sure if there would be much improvement. Rob from CARiD was very helpful and knowledgeable about all of the exhaust systems, and he recommended the Flowmaster American Thunder model. Well, he was right on. I can't be more satisfied with this exhaust system. I had my local muffler shop install it in about an hour, and it sounds great. The more I drive the car, the more I want to drive it. Thanks, Rob, for your help, and I will continue to buy products from CARiD. Ron South4 people found this review helpful.Was this review helpful for you? YesNoShare this review:
