    Features:

    • 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.

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.

    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.

    Sounds Great
    I love the sound and the look, but the installation took a little time as I had to cut over 4" off of the mid pipe and make my own T hanger. But all in all, it sounds great.
