    Review & Installation Video

    Hey everyone, Justin with AmericanMuscle.com and welcome to my breakdown and sound clips of the Pypes Off-Road H-Pipe, available for your 2011 through 2014 Mustang GT. Swapping out the factory mid-pipe on your Coyote-powered Mustang GT is not only a great way to pick up some power, but also can turn up the volume and totally transform the way your Mustang's exhaust sounds. Now, considering different aftermarket mid-pipes for your Mustang, you're going to stumble across a few different options. An off-road version, like we have here, which is going to be devoid of any catalytic converters, or you can go with a catted version, which will often times include a shorty high-flow cat. In addition to that, you can choose between an H-pipe, again like I have here with me today, or an X-pipe version. So what can you expect when it comes to sound? Well, ultimately the H-pipe is going to deliver a slightly lower tone, more characteristic of that muscle car or hot rod sound a lot of us are familiar with. On the other hand, the X-pipe is going to accentuate the raspy characteristics of the Coyote motor, and deliver slightly higher top-end gains, but it should be pointed out that the difference in gains between X and H-pipe will be minimal, at best. Now ultimately, it's going to be up to you guys to decide what mid-pipe will better suit your style and needs. Breaking down some of the finer details here with the mid-pipe, you will notice 16-gauge 304-grade stainless steel throughout, mandrel-bends, solid welds, OE style flanges here for the collectors, and they even of course include your O2 bungs, which have been pre-welded for you. Now, it is important to point out, that this particular mid-pipe from Pypes, is designed to fit Mustang GTs with either the stock manifolds or headers in place or a set of aftermarket shorty headers. Now if you already have a set of long tubes or are in the process of purchasing them, you might want to consider one of the shorty aftermarket mid-pipe options available here at AmericanMuscle.com. Getting the Pypes mid-pipe bolted up to your ride is going to be a little bit more involved than an aftermarket cold air intake or an axle-back exhaust, for instance, so therefore we'll give it two out of three wrenches on the difficulty meter. Now there are a few bolts you will need to access through the engine bay, in addition to some work needed underneath the car, so make sure you have a decent set of extensions ready to go and a good set of tools, of course always helps out. So if you guys are looking for an affordable off-road H-pipe, for your '11 to '14 Coyote-powered GT, be sure to check out the Pypes option right here at AmericanMuscle.com.

    Improves Exhaust Flow. Add even more horsepower and torque to your coyote powered Mustang by eliminating those power robbing factory catalytic converters with a brand new Pypes Off-Road H-Pipe. The Pypes off-road H-Pipe will significantly improve your Mustang's exhaust flow for a notable increase in horsepower and torque.

    Muscle Car Rumble. This free flowing Pypes H-Pipe for the 2011-2014 GT Mustang's not only increases power, but it also adds a deep muscle car rumble to the sound of your exhaust with its classic "H" crossover pipe design.

    Quality Construction. Pypes constructs their Mid Pipes from 3" diameter free-flowing mandrel bent 16 gauge 304 stainless steel tubing, that features a classic H crossover to increase exhaust flow for a significant improvement in power and sound.

    Application. This Pypes Off-Road H-Pipe is designed to be a direct bolt-on for the 2011-2014 5.0L V8 GT Mustangs with either aftermarket shorty headers or the factory manifolds installed. Intended for off-road track use only.

    I have Roush Axel backs that replaced the OEM mufflers. They measure 2.75", will this H Pipe fit the 2.75"? Is there a tranisition peice needed?

    • This h-pipe will connect to the factory exhaust piping between the mid-pipe and the axle back exhaust. As long as the axle back is installed as the new portion of the factory cat back, this mid-pipe will fit flawlessly.

    Tune Required After Install? Would a Tune be required after this install?

    • It is highly recommended to get the most performance gains. Removing the cats will have much higher airflow. Your check engine light will also be on after removing your cats so you can also have that turned off with a tuning.

    Hello! , I understand that this H-pipe requires a tune to remove the check engine light that comes on when you remove your cats. My question is can American muscle provide the proper tune? And I will be purchasing a tuner from you guys as well very soon FYI . Thanks

    • Hello! Yes we do carry tuners that can eliminate the check engine lights from your vehicle. We offer several different options however I recommend a BAMA Tuner, I have a very similar setup on my car, and I love it.

      Easy Install (But)

      Sounds great, fit great only took about 30 min to install it. (took 6 hours to bust loose the basically welded Fallange gasket area bolts (Cat / Down-pipe area) but that isn't Pypes fault. Only complaint (that loses a star) is that it doesn't come with its own *new* gaskets. I had to salvage the old ones. Other than that, easy install and with my Magna Axle backs it sounds amazing!

      Good N Cheap

      The exhaust was easy to install but leaked badly where the cat delete meets the H-pipe just like other reviews say. Contacted Pypes and they told me to try Header RTV to seal the exhaust or take it somewhere to get it welded. They did send me 2 new clamps to try but a couple of $300 pipes shouldn't leak in my opinion. Taking off factory converters can be a huge pita hence the afternoon install time once you get the old exhaust off it takes no time at all to install these pipes.

      Sounds Great

      The pipes fit great, it was an easy one for one swap. I just removed the factory H pipe and then fitted this one in. Shipping was fast and I had my GT rumbling down the road in less that a few hours.

      This h-pipe was the most cost effective combination of sound and power that I could find. The fit is perfect, and I made 403 to the wheels with just this, a cold air kit, and a tune!

      H Pipe

      The H pipe gave the exact sound I was looking for. It is noticeably louder (which I’m sure the neighbors love at 5am)!! Shipping from AM was fast. The install was very easy and only took about 20 minutes. However, taking the factory pipes off was rather time consuming. I did this on the ground with car on jacks. Start to finish was just under 2 hours.

      I love it!

      Once again a great product from American muscle and pypes. Only hassle really was taking them weird bolts out for the cats I’ve never seen before. That took about 3 hours but then once we broke them all off (thank pypes for the extra studs they threw in) assembling took about 25 mins and it was off the lift. We did it on a lift with 2 buddies of mine and it was a breeze. Can’t imagine doing that in the driveway by yourself on your back. After everything was installed and started the car wow instally roared. Pulling out revving it is crazy. Then driving just ecos off everything when you really throttle it but it’s suddle when normal driving and there’s not much difference on drone from just the axle backs I had. In other words these 5.0s should of came stock like this if it was legal

      Loud is an understatement.

      this h-pipe will make your 5.0 absolutely scream. if you want everyone and their mommas to look your way, this is for you. stock headers, this h-pipe, and pype bombs and my 5.0 is ridiculous. i love it. you will need a 3/8th swivel socket, 3 ft extension, and a big breaker bar because the nuts on the cats are insane to get off. make sure you use a 6-point 15mm socket, NOT a 12-point 15mm or you'll most definitely round off the nuts. flange leaks where the h pipe meets the downpipe. once you get those sorted, be ready to literally grab everyone's attention.

      Keeping it.

      Overall I'm happy with it. It leaks though, where the cat delete and h pipe meet, but the echo from the pipes sounds like a leak anyways. Their flange maker needs some training but I'm sure that it isn't that way on every one. Nothing an exhaust shop can't fix quickly. A one piece design would have been so much better. Just getting mine welded up. Great for the price, and after welding I'll still be saving money.

      Install only took about 30 minutes but the uninstalling of the factory cats took about 8 hours, bolts were rusted and kept rounding off. I torch would have helped a lot.

      Happy with the outcome. It was a bit of a pain to install. The brackets could be made a bit better or wider, the fitment ain’t the best. They leak a bit. But for the price I can’t complain to much lol. Good overall

      It’s worth every penny!

      Overall great product! I was unsure between what MOD to do next, this went on sale on Black Friday and I couldn’t pass it up. Overall this wasn’t too bad, however the bolt on the passenger Cat was a massive b*tch. I would recommend professional install if you don’t have proper air tools and a lift. But the end result is WORTH the money.

      Very good product

      Absolutely love this item. It total opens up the exhaust completely, especially for such a cheap mod, bust bang for your buck. Receive compliments all the time. Only issue is the O2 sensor is not really in a good location, the left side of the cat delete was a little too long. Other than that perfect product.

      Don't buy

      Spark plug bung on driver side was welded in the wrong spot, so the o2 sensor is pointing toward the ground.. Drive side flange was made wrong and would not seal.. It looked like someone put their "flange maker" to far back on the pipe then onticed after trying to make the flange then re-flanged it again so the band clamps they give you wouldn't hold the pipes tight to each other so guess who bought a brand new leaky exhaust! With an o2 sensor that's pointing at the ground waiting to get dragged across a speed bump! So if you want a good quality exhaust that fits good don't buy this! Quality control does not exist at the pipes factory
