    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?

    Tytus

    • 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?

    STANGBOSS

    • 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

    TommyboyGT

    • 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.

      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 but they leak a bit

      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

      I was skeptical about how my car would sound with my Borla atak axle back. Let me say People heads will turn!! Car is louder than ever. Need this mod if you want sound improvement it's a must.

      Sounds quiet and tamed but loud on throttle.

      I installed the h pipe without removing the cats. It sounds awesome. Not much for gains probably because i didnt remove the cats. For the price, its worth. must get.

      it was an easy enough install, even on gravel with jackstands, pitch is weird for an h-pipe however.

      2014 GT LOUD!!

      I had this installed after having my flowmaster outlaw axel back and figured ti would be loud I have ran O/R H pipes on other mustangs and loved the way it sounded but these are beyond loud. I honestly could not believe how loud this set up is and I am extremely pleased with the way it turned out! Cruising on the highway sounds good pretty deep and not obnoxious but when shifting through the streets or doing some pulls this thing screams!! Absolutely love it I get compliments every time I drive it! The install would have been possible on my own with my tools jack and jack stands but since the car has been in the midwest the past 3 years the nuts and bolts needed to be heated up in order to get broken loose so I took it to a buddies shop.

      A real head turner!

      Had a local shop install, they had a slight fitment issue with the H connector. They used exhaust mud to seal the issue. I paired the H-pipe with flowmaster Hushpower axle backs. The exhaust note kept traits of the axle back, but now twice as loud at all times. Its really loud, but deep and throaty at lower RPMs. People turn and look before I even pass them. And if someone growls their cute little exhaust in your direction, you can blow them out of the water! Absolute blast to drive with.

      Fitment sucks

      My setup is corsa Extremes, LTH over axle pipes, then I install the off road H and the fitment was terrible. My exhaust sounded terrible under normal driving and extremely loud. It sounded amazing at WOT. I took the delete pipes out and just ran the H-pipe
