Product Details

Ford Expedition 2000, Super 44 Series Delta Flow™ Oval Black Exhaust Muffler by Flowmaster®. Muffler Inlet Diameter: 2.5". Muffler Outlet Diameter: 2.5". Muffler Body Length: 13". Muffler Overall Length: 19". Muffler Sound: Aggressive / Loud. Muffler Structure: Chambered. Muffler Configuration: Offset - Offset. 4" Thick x 9.75" Wide x 13" Case Length x 19" Overall Length. 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.

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.

Mufflers
I was a little sketched out but cause I never bought anything from this company but, they arrived in about 2 days and the boxes they came in were a bit ripped up and it looked like they been thrown around but the mufflers themselves were in great shape, I’m actually getting them on next week and I can’t be happier. IF your thinking about buying this item or just wanting to buy something off this site 100% do it it’s legit, it might hurt the bank a little but it’s worth it in my books. I definitely will be back buying items from here. DREAM BIULD HERE I COME LOL.
