Flowmaster - Delta Flow Technology

The 50 Series HD mufflers are perfect for late-model trucks used in the most extreme conditions. They are constructed of 16-gauge aluminized mild steel or 409S stainless steel. They are fully MIG-welded for maximum durability. The Flowmaster three chamber delta flow design improves the evacuation of exhaust gases from the combustion chambers so the engine can take bigger breaths of fresh air/fuel mixture. This increases the combustion efficiency and improves the torque. A high and flat torque curve is key to performance for trucks used for towing and heavy loads, much more important than a high peak in the horsepower curve. The Flowmaster 50 Series HD mufflers help you to perfect your engine for heavy-duty use.

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.

    Flowmaster 50 Series Muffler.
    The customer service and product quality are both everything that I expected. However, I did have some difficulty with fitment. In my situation, it was not a simple plug and play situation. That's where my local muffler shop got involved. Other than that, I love the products and will continue to shop here.
