Flowmaster - Delta Flow Technology

Like all Flowmaster mufflers, the 40 Series Delta Flow mufflers improve exhaust scavenging for increased torque and horsepower. The precision positioned Delta deflectors have a dual function, as they are positioned to create a low pressure zone that improves exhaust scavenging, while also reducing the interior resonance. The unique design of the 40 Series two chamber delta flow mufflers makes them perfect for performance cars used daily or on long drives. The exterior sound will turn heads, while the interior sound level provides the driver with the beautiful music of a performance engine at a comfortable sound level. The mufflers are fully MIG welded for maximum durability and you have a choice between aluminized mild steel and stainless steel construction.

Flowmaster - 40 Series Delta Flow Mufflers

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

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 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.
