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 stock factory manifolds installed. Intended for off-road track use only.

Perfect

Sounds just like I hoped it would. Got this and Pypes Pype Bombs together. You will definitely KNOW when I head down your street. Couldn't decide between X or H and am glad I went with H pipe

First, i was a bit leery about purchasing this without more feedback. However, the first set of cat backs I had were Pypes, and they were good quality, so I rolled the dice. Installed these without help

tune and fitment Would a tune be required? Would these go along with my pypes pipe bomb axle backs? Thanks

  • A tune is not required, but strongly recommended. Without a tune you will get a couple Check Engine Lights. Yes, these would go great with your axle-back!

  • The mid-pipe and axle-back do not directly connect. You will not have any issues installing this with any axle-back.

How much more horsepower? The description states that this will "add even more horsepower and torque to your Coyote powered Mustang..." I was just wondering how much more you could expect from an otherwise stock GT?

  • Without tune you are looking around 5-7 horsepower. With tune around 15

    This in an awesome offroad H...

    First, i was a bit leery about purchasing this without more feedback. However, the first set of cat backs I had were Pypes, and they were good quality, so I rolled the dice. Installed these without help on jack stands. Header-to-cat bolts are 15mm, one on each side accessible from the top, the other accessible from underneath. The nuts on top required a 24" extension and a 24" breaker bar to pop loose (keep in mind, this car has less than 11k on it). That was the only difficult thing with this install. All welds were of great quality. Pipe bends were top notch and everything fit perfectly. The instructions called for cutting the claps from the factory H, so not sure why the previous reviewer took issue with it. Great sound, very similar now to a pushrod 302, when coupled (at least) by my Roush catback. Highly recommended.

    Enhanced my Roush axleback exhaust!

    One issue during install. The 2 factory clamps that are to be used after bolting the upper section to the manifold are welded to the factory exhaust. The shop that did my install gave me the option to have them removed and tack welded to the new h pipe or they would weld the new parts together. Thats why I only gave 3 stars for fit and finish (otherewise fit and finish were superb)!

    Power Unrestricted!!

    Went on a little run after I installed these H-pipes and wow was my first impression! Let's just say the factory cats restrict a lot of your power! As far as the sound It's not bad considering the fact I still have stock mufflers but I'm sure after I purchase a set of Roush mufflers she'll be screaming! Overall great product best bang for your buck!

    Excellent H pipe. Directions. Definitely a must for 2011+ GT

    I received this H pipe very quickly. Took my time installing on jack stands, about 2 hours. Some suggestions about installing in garage with jack stands: 1- Remove the front first. The top of the bolt is difficult to access. Try different 13 mm box wrenches. Once loose, although not exactly the correct tool, use a 5.5 mm socket on the exposed stud. Loosen up all the way. 2- Loosen the rear H pipe clamps with a long breaker bar. The nuts are 15 mm and a deep well socket works great. 3- Tap the clamp ALL the way back to allow the H pipe to drop down. 4- Wriggle and pull loose the front of the H. The clamps are tack welded on to it. 5- Once out, use a chisel or screwdriver to cut loose the clamps. Clean up the exposed sharp edges. 6- re-install in reverse order. I suggest lining the old and new pipes up on top of each other and tighten up firmly, with a ratchet, the center clamp provided. The factory H is slightly LESS than 2 inches!!! A must have for a 650 hp Roush blown Mustang with stock exhaust. No increase in drone. Much smoother acceleration.

    Nice, but could be better

    First off, I LOVE the sound combined with my Roush Axle back. However, fitment could have been better. The way these are made, they do not sit together very tight so you could go under the car and move the midpipe around just by pulling on it. I dont think it will be a problem just driving around, its just something to think about. These were cheaper compared to other similar midpipes so not terribly upset about it. If I could choose again, I would probably pay the extra to get pipes with a better fitment.

    H Pypes - Install

    Excellent sound with factory FORD Mufflers. THe sound is amazing and the rumble is awesome! The only thing that I experienced bad was when the dealership installed the H Pype and there was a leak. The dealer has to Weld the pipes as clamps would work. Other that this - the H Pypes sound and work Fanrtastic!

    WOW!!!

    The fitment was great install to took 1 hour and 30 min. Very easy with instructions. Sounds amazing paired up with my Pypes axle backs and wow is it loud it just screams its crazy how much cats muffle your exhaust. Overall I'm very impressed with Pypes brand they are definitely the best bang for your buck.

    LOUD

    I had these put on with pype bomb axle back, and it's crazy loud. I attempted to install myself but could not get the factory clamps that you have to use to stop leaking. Had a shop do both items for 100 bucks. I recommend a shop install unless you have a lift and or very mechanically inclined
