Flowmaster

The Flowmaster sound is the true tone of American muscle and performance. Flowmaster mufflers produce more power than performance-robbing OEM exhaust systems and assure that you are getting the most advanced and professionally engineered mandrel bent system available. Each and every single Flowmaster exhaust system is custom tailored to fit your vehicle for an easy installation and to take your vehicle s appearance and performance to the next level. Flowmaster exhaust systems provide improved acceleration, lower engine temperature, a cleaner and more efficient burn in the combustion chamber, better fuel economy, and best of all: that one of a kind Flowmaster sound! What makes a Flowmaster system so unique is that its performance improvement is paired with its unique exhaust tones. The Flowmaster sound is offered in many different tones depending upon the muffler series. From the deep, aggressive tone of the 40 Series to a quiet and subtle, but unmistakably rich tone of the 70 Series, you will find the ideal balance of performance and exhaust sound you want. In addition, most systems are available in either American Thunder or Force II chamber designs. Force II exhaust systems produce a quieter tone making these ideal for daily driving and to keep the others guessing what kind of power you are laying down. But not to worry Force II systems are still noticeable when the gas pedal is punched! On the other hand, American Thunder exhaust systems produce a louder, more aggressive rumble leaving the competition wondering and scared of what you may have under the hood. No matter what setup you choose, Flowmaster exhaust systems have the sound and feel you want and have come to expect from a custom exhaust system.
