Product Details

40 Series Muffler by Flowmaster®. The Original 40 series muffler delivers an aggressive exterior and interior tone. If you're looking for that original Flowmaster sound this is the muffler for you.

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.

Amazing Sound!!!!
I am more than satisfied with this product. You definitely get the bang and growl for your buck, literally. Sounds like I changed the whole engine in my charger.

Flowmaster
I recently ordered a Flowmaster muffler from CARiD and the experience was a very good one. The order was filled very fast and sent. I received it in no time at all. It was in great condition and sound great on my truck, and I couldn't beat the price.

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.

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.
