Flowmaster - Delta Flow Technology

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.

Can't Beat an Original
So many companies try to imitate the Flowmaster original 40 Series. They mostly fall short and you are stuck with the disappointment. The price at CARiD is the most reasonable I found, and the product is the best, especially for American Muscle.

Flowmaster Muffler
I am satisfied with the Flowmaster muffler I purchased. It sounds great as expected and gives the sound of power to my Dodge truck. A good product, I would recommend it to my friends.

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.

Sounds Great
This exhaust really makes the 351 in my F-250 sound awesome. Nice, throaty, husky sound. Love it.
