This kit was one of our most-requested systems since we started our on this cat-back exhaust testing endeavor, and it's by far one of the most unique systems in our massive 2011 to 2014 F150 5.0L Cat-Back Exhaust Kit Arsenal. The Magnaflow Turn-Down Kit is a classic "dumped" exhaust system that doesn't use any visible tips. Instead, the kit comes with a turn-down exhaust tip and very short muffler and tubing that drops exhaust gasses right in front of your truck's rear axle. The kit's no-tip look is actually pretty awesome and it gave our 2012 F150 5.0L FX4 Project Truck a very mean and clean look. The kit also had a great sound, but if you're expecting a booming, ferocious sound, they you're setting yourself up for disappointment. This kit has a deep, mellow sound that is all Magnaflow. So, if you want a more mellow exhaust with one of the cleanest looks out there, this is the kit for you, and you can't argue with its price point or quality.
Just like nearly all of the installs we perform here at Stage 3, we took our kit down to Extreme Performance out in Goodyear, Arizona, to get or Magnaflow Turn-Down installed by Chris, who was ready and able to get yet another kit up and running on our truck. Due to its small size and the fact it just didn't need much hardware, the Turn-Down system was extremely easy to install. The only real difficult part of the whole endeavor was finding a factory resonator pipe, as the kit required it for a proper install. Luckily, we scrounged one up for our Gibson Metal Mulisha® Cat-Back Kit install, so we were ready to go.
If you're like us and you're coming from an aftermarket cat-back kit, then make sure that your stock resonator pipe assembly is reinstalled back on your F150.
If you have the factory cat-back kit installed on your truck, kit the clamps holding the muffler and resonator pipe together with some penetrating oil, let it soak for a few minutes, and then remove the muffler and over-axle tubing from your truck while working them from their hangars from your truck's mounts.
To start off the Turn-Down Kit, Chris installed the intermediate tube by fitting it into the factory resonator pipe and the forward OEM exhaust mount.
One that tubing was in place, Chris fit on the kit's muffler and slipped its hangar through the stock mount on the bed rails, before clamping them together.
With no real aligning needing to be done, Chris tightened down all the clamps that he had already slipped over the exhaust's tubing.
The final piece was this kit's centerpiece: the turn-down tip, Chris connected it to the muffler assembly and threw on a clamp.
And that's it. Seriously, that's all. I know, it's a bit anti-climatic, but this kit was pretty basic and was by far the easiest system we've installed so far. It also sounds perfectly decent, though it's not anywhere near as ferocious as you'd expect. If you do want to make this kit brutally loud, all you'd need to do is cut out the stock resonator or have an exhaust shop fabricate a delete pipe. That being said, getting rid of that resonator has the potential to give this kit a ton of drone and rasp. Be warned! Still, this kit gave our truck a great look and a classic, mellow Magnaflow sound.
