flowmaster exhaust system

Force II™ Stainless Steel Dual Axle-Back Exhaust System (817484) by Flowmaster®, MODERATE SOUND. 60 Series Delta Flow Muffler. Dual Rear Exit. 2.5" Tubing. 3.5" Polished Embossed Logo Tips. The Force II Series is designed for a moderate or mild performance tone experience (depends on application and exhaust type), suitable for everyday street driving. The character of the exhaust sound still has the deep, rumbling tone that signifies power, but at a more subdued decibel level that gives a pleasant performance character to driving without being tiring.



  • Available sound levels: Mild Sound / Mild - Moderate Sound (depends on application and exhaust type)
  • Increases Power
  • Increases Torque
  • Suitable for Everyday Driving
  • Every System Tuned on Dynamometer
  • Perfect Fitment

The Force II system can improve power, torque, responsiveness and mileage for any vehicle and bring true performance rumble to everyday drivers. The performance character of the sound is unmistakable, without being aggressive. It is a power sound that is perfect for long distance or commuter driving, a sound that shows off the muscle of the engine without tiring the driver or drawing unwanted attention from neighbors and law enforcement.

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.

2010 Chevy Corvette / Posted by (Rio Rancho, NM) /

Took my mechanic one hour to install. Has a great Flowmaster hum, serious muscle sound when at full throttle. Very little drone at highway speed. This was the best thing I could've done to my Vette, and I looked all over the web, and this was the best price around. It only took six days for ground shipping.
