  • The Original High Performance Flowmaster Muffler
  • Aggressive Sound for the Enthusiasts Who Love Their Exhaust to be LOUD

The Super 40 Series mufflers are designed for the true performance enthusiasts. The flexibility and control offered by the unique Flowmaster technology has been used to build a muffler specifically for high horsepower road cars. The exterior sound has the exciting tone of a true-blooded racing engine, but subdued to legal limits. As even the most enthusiastic performance engine fan tires from constant high sound volume, the Flowmaster technology also has been used to tune the resonance sounds that reach the interior of the vehicle to a comfortable level, allowing the performance car driver to enjoy the racing music for hours on end without strain.

All Flowmaster mufflers are tuned for maximum performance. All Flowmaster mufflers produce a beautiful deep performance tone. Choosing the right Flowmaster muffler is not a technical decision – it is all up to your personal taste. It’s A Sound Decision®.

Flowmaster mufflers differ in technology and tuning, and thus in tone and character, to give your performance engine a sound to your personal liking.

Flowmaster mufflers employ two unique technologies developed by the company; 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 always has the right muffler for you.

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.
