      Video Review & Installation

      Hey, guys. Adam here with Today, I'm bringing you a quick overview and installation of the Pypes X-Pipe, fitting all 2011 to 2014 Mustang GTs. So, in this video, I'll be going over the sound and expectations of the Pypes X-Pipe as well as its materials and construction. I'll top off the video with the installation, which I'll also let you know upfront will be a very simple job for almost anybody to take care of, so it gets a one out of three wrenches on our difficulty meter. The Pypes X-Pipe is gonna be for any 2011 to 2014 Mustang GT owner out there looking to swap out their factory restrictive mid-pipe to get a raspier or noticeable growl from their exhaust without having to pick up a new set of catalytic converters, ultimately saving you money. Now, with that said, this is all thanks to a couple of different aspects of the product overall. The first aspect you'll notice is that it's an X-pipe-style exhaust mid-pipe, as opposed to your factory H-pipe. That factory H-pipe is designed, just like it sounds, as a factory H-style piping, basically meaning there's a middleman connecting both sides of the exhaust system, which can actually act as a bit of a restrictor for the exhaust flow, ultimately kind of quieting down the sound. Now, swapping over to this X-style design, you are eliminating that middleman, really giving a free-flowing mid-pipe to open it up and give it a raspier race car growl that you might be looking for.So the other aspect of the product that really can rasp up the sound is the materials and construction. This one is jumping from your factory exhaust up to a 3-inch-diameter 409 stainless steel tubing, which ultimately means a bigger piping size, means a raspier growl. Now, of course, this one does jump from the 3-inch all the way down to a 2.75 at the end to ultimately bolt up to your factory exhaust very hassle-free for a perfect fitment.So one thing I do wanna point out before I go any further is that, if you're upgrading to long tube headers or if you already have long tube headers, this particular X-pipe will not be for you. When you go with long tube headers, not only do you have to match the mid-pipe up with the same brand of long tubes, but you have to get a shorty mid-pipe to work with it as well. This particular X-pipe is going to be a stock length X-pipe, reusing your factory catalytic converters, so if you've got the long tubes or you're going with the long tubes, this one will not be able to bolt directly up to it.You can get this for just about $150 and, like I said in the beginning, a very, very budget-friendly option, one of the least expensive on the market. Now, least expensive does not exactly mean cheap. This one is made of a 409 stainless steel, so pretty good quality materials. Of course, it's not the best, but you kind of expect that from one of the budget-friendly options out there.Shifting gears over to the installation portion of the video, like I said in the very beginning, this one's simple enough for almost anybody to take care of with light mechanical skills required. All you'd have to do for this one is jack your car up, support it on jack stands, or if you have a lift, it makes it a lot easier, of course. Unbolt and unclamp your factory mid-pipe, of course, leaving your cats where they are, because you'll be reusing those. With your factory cats in place, remove your factory mid-pipe, swap it out for this X-pipe from Pypes, and you're good to go. Overall, about an hour's worth of time in the driveway at home and a one out of three wrenches on our difficulty meter. Wrapping things up here, if you're the owner of a 2011 to 2014 Mustang GT and you're looking for a very budget-friendly X-pipe replacement to your factory H-pipe for a raspier growl overall, you might wanna check out the Pypes X-pipe, which, of course, can be found right here at

      Improves Exhaust Flow. Ford actually did a nice job on the stock Catalytic Converters, but the factory H-Pipe could actually use some improvement. That's where the Pypes X-Pipe comes into play. Designed to balance out the exhaust gas pressure in your system, this X-Pipe reuses the stock Cats saving you money.

      Race Car Growl.
      This free flowing Pypes X-Pipe for the 2011-2014 GT Mustangs not only increases power, but it also adds a loud raspy, race car growl to the sound of your exhaust with its modern "X" crossover pipe design.

      Reuses Stock Cats. The Pypes X-Pipe bolts up directly behind the stock catalytic converters with no cutting required saving you time and money. By reusing your stock catalytic converters and stock clamps, you ensure that your Mustang is smog-legal.

      Quality Construction.
      Pypes constructs their Mid Pipes from 3" diameter free-flowing mandrel bent 409 stainless steel tubing and has a reduction in the rear to hook up to your 2.75" factory cat-back. This Mid Pipe features a merged X crossover to increase exhaust flow for a significant improvement in power and sound.

      The Pypes X-Pipe is designed to fit the 2011 to 2014 GT Mustangs with either the stock exhaust manifolds or aftermarket shorty style headers installed.
