Flowmaster - Delta Flow Technology

The Super 40 Series mufflers are designed for the true performance enthusiasts. The flexibility and control offered by the unique Flowmaster technology has been used to build a muffler specifically for high horsepower road cars. The exterior sound has the exciting tone of a pur sang racing engine, but subdued to legal limits. As even the most enthusiastic performance engine fan tires from constant high sound volume, the Flowmaster technology also has been used to tune the resonance sounds that reach the interior of the vehicle to a comfortable level, allowing the performance car driver to enjoy the racing music for hours on end without strain.

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!

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.

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!

I absolutely love the sound of it! Install was pretty quick. The only thing I don’t like is the clamps. The clamps didn’t fit right and didn’t clamp tight enough. Other than that, it’s amazing!

It's Perfect, I Love It
After pulling the trigger on the Outlaw, it arrived quickly so I was really pleased with the CARiD service in that regard. With the help of my son we got it installed in a few hours, and like many other reviewers have said, the hardest part was getting the old muffler off, and mine wasn't even that rusty. Ended up just cutting it off with a Sawzall. After the initial fire-up, I was worried that it was going to be way too loud. The truck was backed up to the garage so it formed a kind of amphitheater that made the rumble reverberate conspicuously throughout the neighborhood. My son was totally stoked, but in my head, I was like in my head "Oh S*** I can't live with this, and not only that but I cut the old muffler off." But then the idle settled down after a minute, and ultimately it wasn't much louder at all than stock at that RPM. We took it for a spin and, in the final analysis on the initial impression, the muffler was a perfect balance between quietly rumbling when you want it to (idle, and just cruising around), and aggressively lively sounding when getting on it. In other words, it was only loud when I wanted it to be. I've now had the muffler for a few months and I have not a single regret. It always gives me grins when I fire it up on cold start. It's like the truck is saying, "Ok let's do this," even if you're just going to the store. I can also appreciate the many "moods" of the engine now that it can communicate better, depending hills, freeway acceleration, backing off the throttle and basking in the mild burble, or mashing the pedal to pass someone or just be a hooligan in private. It's never too loud.
