Flowmaster mufflers differ in technology and tuning, and thus in tone and character, to give your performance engine a sound to your personal liking. This is what Flowmaster calls giving you “The Power of Choice.”

Flowmaster race mufflers employ two unique and patented technologies developed by the company; Delta Flow™ and 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. No matter what you are racing, Flowmaster always has the right muffler for you.

The original Flowmaster technology was born on the racetrack over 25 years ago. There was urgent need for a sound solution for Sprint car racing at local California fairground events. Their sound level of the Sprint cars was deemed too high and the continuation of the racing was threatened by protests over the excessive noise. Flowmaster founder Ray Flugger invented and patented a new and innovative technology that not only resolved the excessive sound issues of these high-powered racecars, but also increased maximum horsepower and provided an increased and broader torque curve - an unheard of byproduct from competitive mufflers in use at the time.

The highly devoted R&D department of Flowmaster Inc. actively searches for new challenges to resolve, and is constantly working with leading race teams, engine builders and race organizations in the quest to improve and develop new technologies. Flowmaster’s developers are focused on developing greener, more positive solutions to keep racing safe for all participants, fans and neighbors, while achieving the ultimate goal...Winning! No other muffler company has dominated racetracks around the world like Flowmaster has in the past and present. Nor will they in the future. That's the Flowmaster pledge to customers. The company is confident to make that statement, trusting that its developers will constantly produce ground-breaking improvements in muffler technology.

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.

Very Well Made - Fits Perfectly.
Flowmaster® - FlowFX 409 SS Oval Gray Exhaust Muffler
I installed this on my truck in about 2 1/2 hrs. I'm a decent mechanic and have plenty of tools but no lift. First, I had to get the truck up on jack stands so I could shimmy in/out under the running boards. The factory clamps are spot welded to the muffler in the rear with the nuts on top. The impact wouldn't fit, so I just cut them off. The front nut wouldn't budge, so cut that off as well. The rear pipes came out with a little persuasion (hammer), and the muffler came off the front pipe pretty easy with a few twists. Next was laying on my back while trying to release the muffler from the hangers without it falling on my face. Once it was off, the reassembly was a snap. The muffler fits perfectly, and the tailpipes are in the exact same spot they started. Sound - Quite a lot louder with a very deep resonant tone. Sounds great on a cold start and isn't terribly loud until you really get on it. I can no longer hear the intake noise under hard acceleration. There is a fair amount more interior volume (drone), and I'm a little concerned it may be annoying on longer trips (when towing my camper) but we'll see. If you want to be discreet, stay off the gas. If you don't, people are definitely going to notice you.
