Flowmaster - Delta Flow Technology

The 70-Series was originally designed for trucks, giving them the powerful Flowmaster sound at low decibel and resonance levels. Despite being designed to be the quietest Flowmaster mufflers, they have been used in extreme racing applications where high horsepower engines demand a large sound cancellation chamber so as not to lose power or torque to meet noise regulations. The 70 Series mufflers are perfect for high performance street cars, most trucks, SUV’s, RVs and tow vehicles that require quiet operation with improved sound. These mufflers are constructed of 16-gauge aluminized steel and fully MIG-welded for maximum durability. 5" Thick x 10" Wide x 22" Long with inlet/outlet sizes from 2.25" up to 3".

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.
