Aggressive Design with Brutal Sound and Volume

Our friends over at Magnaflow are more known for their subtlety than outright noise and volume, but they're ready to turn that reputation on its head with this aggressive 3" Turn-Down cat-back exhaust. This kit features a dumped exhaust tip right after the muffler that pours exhaust gas right into the pavement (or dirt) directly underneath your truck with minimal muffling. The kit's aggressive muffler design and unique style let it produce a huge, throaty roar that you and everyone will instantly notice. Magnaflow's Turn-Down cat-back exhaust kit can even get your 2011 to 2014 F150 3.7L, 5.0L, or 6.2L better performance by reducing back pressure and restrictions for some mild horsepower, torque, and fuel economy gains all in a system with a very simple installation.

2013 F-150 5.0

Very cool Exhaust. Easy to install and sounds great. Not too loud while cruising at highway speeds. Does give good sound when you step on the gas.

2011 Ford F150 FX4

The 5.0L Coyote is arguably the best engine Ford ever built. Unfortunately, they spent a lot of time & money to make it practically silent. I wanted my truck to sound angry and powerful, but I don't crave constant attention like my neighbor who owns a BMW with straight pipes. Needless to say, everybody hates him. I installed this exhaust on my FX4 along with Airaids's cold air intake. At an idle, the truck now emits a menacing rumble, but without being pretentious. Step on the gas, and a ferocious yet subdued roar fills the cab and immediate area with the sound of rage that puts a smile on my face and doesn't make my neighbors curse. Installation is easy, I did it myself with a socket wrench & WD-40. It's expensive, but worth every $ to bring the natural rage out of your Coyote.

Well this kit add gas mileage?

Asked by: Richard Jackson - 4/23/2022

It likely will not. This system is a cat-back system only, and cat-back kits alone do not generally affect fuel economy one way or the other.

I already know this will fit my 3.7 f150. Everyone says that this exhaust roars like a jet when you step on it, but not super loud at idle, which are both what I want. However, I assume these are with the Coyote. Does anyone know if it has the same or a similar effect with the 3.7?

Asked by: Joseph - 2/11/2022

You'll get at least a similar effect with the 3.7L, though by its nature, the 3.7L is a bit quieter and has a different tone than the 5.0L V8s and the 3.5L EcoBoost trucks.
