    Review & Installation Video

    Review & Install Video

    Hey, guys. Adam here with americanmuscle.com. 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 americanmuscle.com.

    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.

    Application.
    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.

        I already have this mod installed to my factory headers, If I want to buy the BBK ceramic or stainless Long tube headers 1" 7/8 will I be able to attach right onto it??

        • The Pypes X-Pipe (11-14 GT) is designed to fit the 2011 to 2014 GT Mustangs with either the stock exhaust manifolds or aftermarket shorty style headers. When doing long tube headers you will need to get a shorty mid-pipe which would also need to be the same brand as the header.

        Does this bolt on front and back? Or does it need to be welded on? I've read conflicting information in the reviews about what's required to complete the install.

        • This pipe does not need any welding, it bolts right on in place of the factory H-pipe.

        My car had this xpipe previously installed on it before I purchased the car. The flanges were cut off and the xpipe was welded to the stock cat pipes. I have already purchased the Pypes cat delete pipes from American Muscle. I'm assuming that the Pypes cat delete pipes are sold with this exact xpipe when you purchase the entire unit. Is that correct? Just trying to verify so that there are no hiccups when I install. 1 answer

            Gonna have to cut the old clamps off

            My X pipe fit perfectly. The only problem was the old clamps on the cats cannot come off because the nut is on top and you cannot get it off with any tool. So you will need to cut off the old clamps and make sure you buy new clamps to attach the X pipe to the cats. Other than that, it is a great fit. Slightly more aggressive tone. You notice it more later on.

            Quiet

            So I'm not entirely sure why but AM sent me cat delete pipes with this xpipe. I'm waiting on a tune to go catless but for now I have just the xpipe installed. the install wasn't difficult but did take a while due to cutting the clamps and welding them back together. I could've just used the clamps you guys sent to me with the cat deletes but I forgot those even existed until afterwards. as of right now one of the clamps isn't on properly due to the bolt being broken (probably because it's lowered) so it has a leak. I have roush axlebacks (black tips) with a resonator delete and before this it was obnoxiously loud which I liked but with this on it's so much quieter but has a better sound to it. I'll post another review when I get the cat deletes on.

            Don’t get it

            Don’t get it it’s a waste of money and time. You’ll have to spend a lot more money and time and in the end it’s just not worth it. I barely just got it and I already returned it. It doesn’t come with clamps or flanges which which doesn’t make sense and the guy at the muffler shop said it would be a lot of work and it would cost me a lot of money to put it on. Again it’s a waste of time and money and I would strongly advise listening to the reviews and not getting it.

            Deeper Tone

            This product sounds great, however, it required some professional installations on my 2014 Mustang GT. The pipes were to short and needed to be welded in place. The cost for the welding was about $70.00 so the over all cost was still considerably less than a more costly X-pipe. The exhaust note is sweet to my ears and I might add to many other that have commented ears as well.

            easy and affordable

            I like the sound of the x pipe was looking around found it on here ordered it got it within the week went to install it the cat pipes were about a 1/4 inch further apart then the x pipe were was able to get it on I would recommend getting new clamps or using the old one off the factory axle back mufflers and using some copper RTV no leaks will made piece would recommend it to anyone

            Had a shop to install, but they had difficulty. X-pipe didn't meet up with factory header, and it has an exhaust leak on left side, going to have to carry car too muffler shop to see what can be done.

            It’s literally just pipe, no clamps .... nothin , took forever to find and get new clamps that weren’t a million dollars , new clamps were 160 bucks for the one side and like 30 bucks for the other 2 , then took to a shop to have installed and they said it didnt fit well , its on the car now but if i knew it was going to be all that hassle I would have just had a shop make one up

            The pipe is decent, you get what you pay for, it didn’t fit the cats the pipes were to far apart so I used a come along strap to bend them closer together so it’ll fit the cats

            DO NOT BUY

            Save your money and buy another brand. This piece has terrible fitment and the flanges are too big to mate to the factory cat pipes. IT WILL LEAK. DO NOT BUY THIS. You have been warned.

            This xpipe not only gave me fitment issues, but gave me an exhaust leak too. I took it to a shop and had to have them weld it on. The sound definitely interferes with the magnaflow otlaws axel back as well, save up more money and get a different x pipe.
