Product Details

Super 40 Series Delta Flow Muffler by Flowmaster®. The 2-chamber design of this muffler, incorporating the patented Flowmaster Delta Flow Technology, has enabled the company to create a performance muffler with an aggressive exterior sound combined with a subdued (but noticeable) interior resonance. This is a muffler that makes a true performance statement without being overly tiring for the driver.

Flowmaster - Delta Flow Technology

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.

Perfect
Relatively quiet, yet has that perfect Flowmaster throaty growl. I love the sound! Very minimal interior drone on my 2004 Ford Expedition mounted in stock muffler location, less in fact than my stock exhaust with a small exhaust leak at the oem muffler. I highly recommend it for any daily driver looking for a more aggressive sound without pissing off your neighborhood! It also is very well labeled as far as inlet/exit, so if you have an shop install it for you, it’s nearly impossible to screw that up!

Flowmaster Muffler
It looked very good, i like black, was easy to install. The sound is exquisite it louder than a straight piped truck and improved my mileage from 14-16 mpg.

Sounds Good
I was very happy with the 40 series Flowmaster. Sounds like a truck should, has a nice clean deep tone! The staff at CARiD.com matched it perfectly to my truck specs! Thank you, guys! I look forward to my next order.

Great Muffler
I bought this muffler for my wife's 2007 Tahoe. She wasn't too excited when it showed up in the box, but after we welded it up, you should have seen her face. I would buy this muffler again, it sounds great.

Love it! Sounds great and easy to install, and the price was right. I saw other places wanted twice the price as CARiD.com.

Superior Sound
Just put this muffler on my truck with all new aluminized pipe from Cats. to bumper. When peeling off the rotted exhaust from my 2008 F150, I seen it was Flowmaster also..... The entire back of the muffler rotted out letting the right tailpipe drag on the road. Hope this holds up well. Hmmm. Sounds great though. I would have given a higher rating if there had been a Tshirt in the boxes.
