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 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.89.99Brand: Flowmaster Part Number: 942043 UPC: 700042015429
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® - 40 Series Delta Flow™ Muffler Reviews (10)

Money well-spent. Delivered on time with all necessary pieces. Installation was a breeze, only taking a few hours, and no helping hands were needed. Installation was conducted in the parking lot of my apartment complex after dark due to hot temperatures. Best of all, I didn't need to jack up the truck (no lift kit either). Instead I used my jack only to support the muffler throughout the process. After driving the first few times, I recommend going back under one last time to check the clamps and tips after heating up. Now my truck has a moderate powerful sounding rumble at start up idle and cruise speed.Was this review helpful for you?

I would recommend this product and website to anyone. I ordered the wrong size of tailpipe, and I called customer service, and they were very helpful. They explained everything that they were going to do and everything I had to do.Was this review helpful for you?

As a Mopar guy who owns a Challenger with headers and dual exhaust, the American Thunder was too loud inside the Durango. It sounds great on the outside and does deliver improved horsepower/performance. Solution, my muffler guy installed one glass pack on each side before the rear axle. Problem solved. You don't loose any performance, but it is a comfortable sound on the inside while still sounding huge on the outside. I would do it over again knowing what I know now. I am happy with the results.Was this review helpful for you?

The appearance of this exhaust is great through and through. The installation was very easy and 100% satisfying. The price is right for the quality of the product which makes it a great value.

This exhaust system is not from the cat back, there is a piece of pipe 22.5" long that they don't include. My muffler had a 11" piece of pipe welded to it, they illuminate it, witch is not a problem. I would have gave it a 5 star if not for that pipe.Was this review helpful for you? YesNo(4.5)APPEARANCEEASE OF INSTALLATIONPRICE/VALUEQUALITY(5)APPEARANCEEASE OF INSTALLATIONPRICE/VALUEQUALITY
