Flowmaster - Delta Flow Technology

Greatly reduced interior resonance, smaller case size, and moderate exterior tone are just some of the benefits to the 50 Series Delta Flow Mufflers. With a specially designed Resonance Tuning Chamber, the 50 Series Delta Flow gives all the performance, while reducing the tone inside and outside of your vehicle. Simply stated, it delivers the same great performance from Flowmaster, without the increased sound. Available in Aluminized Steel or 409S Stainless for harsh weather applications. Both versions are fully MIG-welded for maximum durability.  The overall measurements for this muffler is 4" Thick x 9.5" Wide x 17" Long with inlet/outlet sizes from 2" up to 3". A 3” thick version is also available, as is a narrow 8.5” wide version.

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.
