Product Details

40 Series Delta Force™ Aluminized Steel Oval Black Exhaust Muffler (42441) by Flowmaster®. Without Hangers. Muffler Inlet Diameter: 2.25". Muffler Outlet Diameter: 2.25". Muffler Body Length: 13". Muffler Overall Length: 19". Muffler Sound: Aggressive / Loud. Muffler Structure: Chambered. Muffler Configuration: Offset - Center. The Delta Force 40 series race mufflers utilize Flowmaster's patented Delta Flow technology and feature excellent power characteristics with good sound reduction qualities. Recommended for all racing applications where mufflers are required with a substantial decibel reduction over open headers. Please call the Flowmaster tech-line for assistance with specific decibel requirements and applications.

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 TRUCKiD is the most reasonable I found, and the product is the best, especially for American Muscle.

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.

Outlaw

First of all, I love this muffler. The sound is amazing. Install was pretty easy after busting my knuckles getting the stock muffler off. The only thing that I found that I would change is the clamps. The clamps wouldn’t get tight enough to seal the tailpipes and they can still be moved around. Other than that, it’s great.

First of I love the sound of this muffler! Install was a breeze after taking off the stock muffler. The only thing that I found I didn’t like were the clamps. They didn’t get tight enough and could still move the tailpipes around. Other than that it’s perfect!
