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.

Not as loud as the stock hpipe
I have roush axelbacks on and everything else was stock before i put this xpipe on. back clamps came off easy, and so did the front right clamp, but that front left one for some reason everyone had trouble with. I spent two hours trying to find new ways to get that clamp off and put literally all my strength and effort with a simple 1/2 wrench to get that thing off, and once i got it loosened, it took me like 20 minutes going back and forth loosening it with because there was only so much breathing room with trying to get it off. once it was off the stock hpipe came off and i was ready to put the new xpipe on. i put on the xpipe and took it off so many times bc there was air leaking in the front clamps so i knew the best option was to weld it, but i refused over and over after my friend told me because i didnt want to put it on and dislike the sound and be stuck with it. Thank god i didnt weld it! After hours and hours off destroying my shoulder blades and arms trying to get that xpipe in place, we finally got it in the right place to where it looked like it would fit perfectly. since it was jacked up, we used a long wood board and wedged it behind the xpipe (in the middle where it meets) and zipties to push it forward to get the perfect fitment into those front clamps to where it felt like it was in perfectly, unwedged the wood and cut the ziperies. turned it on and there was still air leaking. so, we tightened it as tight as possibly to where the bolts wouldnt move anymore. turned it on again, a lot less air leaking, but still it was there i could feel it. but the most important was, it was quieter than the stock hpipe! it didnt even sound as good! it was probably 75 sound of what the stock hpipe gives you. it almost made my car sound like it had a problem and a full on leakage, or even a blender was underneath. i did research and the more i looked i decided this xpipe wasnt for me. i want more of a deep muscle car sound like i got with the axelbacks, but louder. my next move will be trying to sell my xpipe and get an hpipe instead and a resonator delete, because unlike the raspy sound the xpipe gives you, the hpipe gives it more of a gurgled muscle car sound. my car was barely even popping anymore once i took it to work today, and it made me feel embarrassed that it didnt sound as good and loud as it used to around my friends. if you’re looking for a midpipe thatll give it more of a muscle car gurgle, go with an hpipe, and dont weld something on before you know if you like or dislike it because it could be a waste of time and money. tomorrow im converting back to a stock hpipe and hopefully over the weekend i can do a resonator delete to make those roush axelbacks sound even louder like the videos ive watched, but yeah the xpipe isnt my taste at all. hopefully this review helpsHelpful (0)

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.Helpful (0)

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.Helpful (1)

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.Helpful (4)

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.Helpful (1)

Leaks as everyone already stated
Leaks from flange at connection point to cats as everyone stated, should have listened to the reviews.Helpful (2)

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 anyoneHelpful (1)

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.Helpful (2)

Great product, install difficult
Love the way it sound and really good material but the stock clamps that you are suppose to transfer are too big. I need a shop to weld it.Helpful (1)
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.
Will this product fit with my Roush Axle Backs?
Hi, This Pypes X-Pipe will work fine with your Roush axle backs.
Will this fit the pypes longtubes?
No, you'd want thePypes X-Pipe listed that is is for 11-14 GT w/ Long Tube Headers. This x-pipe is for stock or shorty headers.
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.
Are these the same as the off-road pipe I wanted too add stock cats but not sure if you are able too do that with pypes off road dipped?
This will not cause a check engine light.
This will work with any catback with a 2.75" diameter.
This will fit with the factory headers yes.
Yes, this will work with that axle-back exhaust.
This will not work on BBK long tubes. You will need a BBK shorty mid-pipe to work.
Yes, this x-pipe is compatible with the Magnaflow cat-back exhaust.
Welding is the best option if you want to avoid the need to purchase replacement clamps. It is recommended that the stock clamps be used when installing.
The Pypes X-Pipe will work with the SLP loudmouth exhaust.
The only cutting required will be for the tabs that hold the clamps to the OEM exhaust so that the clamps can be reused. No other cutting is required.
We have not tested these two products together, and while they should work together, we cannot confirm this, as they are designed to work with stock parts, and minor changes in either aftermarket part may not make them compatible with one another.
