              Features:

              • Available sound levels: Aggressive Sound / Moderate Sound (depends on application and exhaust type)
              • Increases Power
              • Increases Torque
              • Every System Tuned on Dynamometer
              • Perfect Fitment

              American Thunder gives you exactly the sound that is promised by the name of the series. The exhaust sound of the American Thunder system has become a symbol of American power that is recognized all over the world. American Thunder is the most popular of the Flowmaster exhaust systems, enhancing power, torque, throttle response and mileage for automobile enthusiasts all over the world.

              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.

              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.

              Warranty Information

              Find out everything you need to know about the product warranty

              Lifetime Limited Warranty applies to Flowmaster stainless steel mufflers, stainless steel exhaust systems, stainless steel pipes and other stainless steel exhaust accessories (except exhaust tips).

              Three (3) Year Limited Warranty applies to Flowmaster aluminized steel mufflers, aluminized steel exhaust systems, aluminized steel pipes, exhaust tips and other non-race exhaust accessories.

              One (1) Year Limited Warranty applies to Elite Series exhaust headers. Flowmaster, Inc. (“Flowmaster”) extends the following limited warranty to the original purchaser of its mufflers, exhaust systems, pipes, exhaust tips, headers and other non-race accessories (hereafter “products”), excluding catalytic converters sold under the Flowmaster® brand.

              Flowmaster warrants the products mentioned above against defects in materials and workmanship for the period set forth below, when they are owned by the original purchaser and remain installed on the vehicle on which they were originally installed. This warranty is void if the product was not installed properly on the vehicle, was installed on a vehicle for which it was not designed, or was removed from the vehicle on which it was originally installed and reinstalled on another vehicle. This warranty shall not apply to normal wear, cosmetic issues such as coatings and material discoloration, any product that was installed on a racing vehicle, installed improperly or contrary to Flowmaster instructions, altered, misused, repaired, damaged from an accident, collision, undercarriage road impact or debris, or willful or negligent act.

              The warranty set forth herein for Flowmaster® stainless steel mufflers, stainless steel exhaust systems, stainless steel pipes and other stainless steel exhaust accessories (except exhaust tips) extends for a period of the life of the original vehicle the product was installed on. The warranty set forth herein for Flowmaster aluminized steel mufflers, aluminized steel exhaust systems, aluminized steel pipes, all exhaust tips and non-race exhaust accessories and commercial applications of aluminized steel products or stainless steel products extends for a period of three (3) years from the date of original purchase and the original vehicle it was installed on. The warranty set forth herein for Flowmaster exhaust headers extends for a period of one (1) year from the date of original purchase and the original vehicle it was installed on. Header warranty does not cover damages caused by exhaust insulating wrap, and is void if the product was installed on a new or rebuilt engine during the initial break-in period.

              To make any claim under the terms of this limited warranty, the original purchaser MUST either return the product to the original retailer or directly to Flowmaster. If the original purchaser elects to return the product to Flowmaster directly, he or she must first contact Flowmaster and obtain a Returned Material Authorization (RMA) number. Once the RMA number is received, the original purchaser may return the product to Flowmaster® at 1500 Overland Court, Sacramento, CA 95691 (or such other address provided by Flowmaster) along with the RMA number and Proof of Purchase of the covered product. The Proof of Purchase must clearly show the place of purchase, purchase price, product purchased, and date of purchase. If upon inspection by Flowmaster the product is found to be defective in material or workmanship, Flowmaster shall at its option, either exchange the product for new product with the same part number or refund the original purchase price.

              This warranty is not contingent upon the purchaser’s completion of the Warranty Registration Form found on the Flowmaster® website. If however the purchaser completes and submits that form at the time of purchase, Flowmaster will keep that form on file which may serve as an aid in determining warranty coverage in the event of the loss of the original purchase receipt.

              Flowmaster’s liability is expressly limited to the replacement of the product or refund of the purchase price as described herein. Flowmaster® shall have no liability for the cost of installation or removal of the defective product, the cost of labor or any additional parts required to complete the installation of the replacement product, towing or transportation costs, or return shipping costs. In no event shall Flowmaster be liable for any direct, indirect, special, incidental or consequential losses and/or damages, including but not limited to interruption of business or loss of business or loss of profit or damage to related components resulting from the use of or inability to use the product, or any breach of warranty or any defect in the product, even if Flowmaster shall have been advised of the possibility of such potential losses or damages. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you. This warranty gives you specific legal rights. You may also have other rights which may vary from state to state.

              The warranties set forth herein are exclusive and unless otherwise required by applicable law no other warranties are made by Flowmaster® or are authorized to be made with respect to the product.

              Magnuson-Moss Warranty Act:
