      Hey, I'm Justin with, and I'm taking a closer look at Pypes polished long tube headers fitting the 4 Valve 5 L coyote motor found in all 2011 and newer Mustang GTs. These headers are constructed from durable 304 grade stainless-steel, including the tubing, which has all been Mandrel-bent to improve your exhaust flow. Now these headers also featured a step up design, which basically means the 1-in-5/8ths inch tubing steps up in size as it leads into this massive 3 inch collector which can definitely improve your performance. You'll also be able to notice this bright polished finish, which is sure to look good under the hood, and help reduce any possible corrosion, so they remain looking good for years to come. If you're not familiar with long tubes, then you should definitely keep a few things in mind. First and most importantly, you're going to see the largest gains in both horsepower and torque, which is by far the biggest plus. Now, those extra gains come with a little bit of extra work. For one, the install will be slightly more involved. Secondly, you will have to modify your Mid Pipe as well. Now in this case, Pypes recommends using their shorty X-Pipe, just for proper installation. When it does come time for install, it'd be a great idea to leave yourself a full day, just to tackle the job. Now again, as I mentioned earlier, in order to make this a 100% bolt-on affair, you will need to pick up Pype's shorty X-Pipe, to bolt everything on without modification. Otherwise, you will need to get some custom work done by your local exhaust shop. So in the end, what you can expect from using Pypes polished long tube headers are considerable power gains, improved throttle response, and a slightly more aggressive exhaust note, especially when compared to your factory manifolds, or a shorty setup, all for a price that's very reasonable. So be sure to check them out today, right here at
