Description
Improves Exhaust Flow. Remove those power robbing factory catalytic converters and release hidden power with a Pypes Off-road X-Pipe. This Pypes off-road x-pipe creates more power and torque than a traditional H-Pipe by merging the exiting exhaust pulses at the "X" which results in less exhaust back pressure for more power.

Race Car Growl. This free flowing Pypes X-Pipe for the 2011-2014 GT Mustang's 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.

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

Application. This Pypes Off-Road X-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.

Fitment: 2011 2012 2013 2014 Details

Great fit and finish

Easy installation. Works great with the Pypes violator cat back super system. Really woke my car up performance wise and the neighborhood because it is loud. Great fit and finish.

Mac24

  • Yes this is a bolt on system but it requires some tweaking to get to fit just right should really be done on a lift and some mechanical know how.

Fitment The JBA mentions bolting on to factory exhaust because it is 3in to 2.75in. Will this affect the fitment of this part?

Hysteric

  • Are you asking if this will bolt to the factory overaxle pipes? if so yes the pipe steps down to 2.75 inches at the back. I have this on my car so you can take my word

3" piping needed? I was wondering if you must also add a 3" pipe from the x to the axel or if it drops down to 2.75"? Also, which muffler would sound best?

    Good Product Overall

    This x pipe really made a difference in performance by removing the old restrictive cats. The install was a bit of a pain as Pypes does not include clamps. Ended up with a leak so decided just to weld it on instead. It also has this annoying hissing sound coming from the actual "X", thought it was another leak but thats jut how the pipe is. Other than that the X Pipe really woke up my car and its not as loud as everyone thinks. I have it paired with the Roush Axlebacks and i sounds amazing. If you want loud though, you have to also remove the resonators... which i just might do ;)

    product shipped fast and was in perfect condition. The instructions say that it comes w new hardware? I did not receive new bolts and nuts for the downpipe to mani connection. Onto the install; I did this in my garage on jack stands. It took me 2hrs to get the pass side nuts loose on the cat (rounded the one under the car off) I finally got it lose and the rest of the job went well. I started at 6pm and finished at 1130pm when I uploaded my tune and cranked the car up it made me jump a little... It's loud!! And sounds mean as all heck. I'd recommend this x pipe to anyone and I am very pleased w my purchase

    Disappointed in the Pypes Off Road X pipe

    The packaging of the product and condition were great when I received it. The installation instruction are also good and easy to understand. The is a simply product to install. I followed the instructions step by step. After all was said and done I could not get the cat delete down pipes to line up with x pipe. This ultimately created an exhaust leak on both sides of the car. I could visually see that the down pipes had been bent/welded incorrectly. I took it to a muffler shop and they confirmed my suspicions. One down pipe was pointing up while the other pointed into the middle of the car. The only solution was to have the two peices welded together. So plan on spending another $80 after purchase.

    An Honest and Thorough Review

    I will be 100 honest - I tried to install myself and the notorious passenger side cat. bolt was so rusted that it was impossible to break with my hand tools. I then took it to a shop for them to install, and the OEM cat. clamps are un-salvageable (luckily I had spares from my axleback install, otherwise they are 50$ each from Ford). Hard to believe Pypes wouldn't include new clamps. This pipe does not exactly fit perfectly and the guys had to eventually weld it into place to create a seal. Do yourself a favor and take it to a shop. 2/5 stars for fitment. Now once things were finally sealed into place, the real beauty of this thing hit me. It sounds like a Ferrari at anything over 4k RPM, and I'm dead serious. I installed an Airaid Race CAI and a BAMA tune the same day, so it most likely is a combination of all 3 upgrades. However, on my way home from the shop (before I installed the CAI/tune), I definitely noticed a difference in torque - and the way the engine was able to breathe. I am absolutely in LOVE with the higher pitched, raspy, purr that emanates from the throat of this X pipe. It literally sounds and feels like a different car. 5/5 for sound and performance gain. And finally, what I like most about this product is that even with the cats deleted (I still have my resonators), it isn't obnoxiously loud. Only on cold morning startups and when I punch it does it sound like a demon (again, dead serious). But once the engine is warm and at idle, this thing is hardly louder than stock. No drone on the highway whatsoever.

    Sell your stereo! You won't use it after you buy this

    I wanted an aggressive tone for my 2011 Mustang RS2. The Roush axle-back exhaust sounded great but I wanted a little more roar and punch off the line. The Pypes X-Pipe mid exhaust system was exactly what I needed. Paired with long tube headers the sound is unmistakable. The raspy note tells other drivers that this is not just an ordinary pony car. A Bama tune update helped keep mileage about the same while increasing HP. I haven't Dyno'd it yet but the increased pedal response alone makes me believe the gain claims. I don't own a lift in my garage so I had the system professionally installed. The hardest part the mechanic claimed was removing the rusted original hangers and bolts. There was no way of reusing them. Keep that in mind if you are going to try a weekend garage swap. He had to zig saw the original bolts out. All in all, very happy with the purchase. At first I was a little worried the loud exhaust would be too much, but now I have learned to turn off the radio and enjoy the roar.

    poor mounting flanges

    The right rear subframe bolts rub... the joint between the cat delete and X-Pipe would not seal and had to be welded. I have to pull the exhaust back out again because it leaks when the car is cold. I am VERY disappointed with the product and would not recommend it. I will be replacing this soon and putting my cats back in.

    Big Difference

    I'am running jlt CAI, x4tuner, ford racing 3.73, bmr lower control arms, and this beautiful off road xpipe with pypes pype bombs. First off I had plenty of people that tried to tell me, oh this setup with the pype bombs is going to be way to loud, well guys I'am glad I did not listen. It's no where even close to being to loud IMO, sounds like a beast, just like I want it to. The sound it makes with the pype bomb are AMAZING! The added power the xpipe makes has changed my car completely! With this setup my car is putting down over 400 rwhp and is turned my car into a street monster! Bama sent me the tunes for this setup and guys they nailed it, they gave the power I was wanting, and the race tune for this setup is ridiculous,listen to me stop reading this and buy this xpipe already! Must have!!
