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 and Tuning 1. Will this fit a 2012 Boss? 2. Will I need a tune to keep the engine light from coming on? Thanks

1badboss Year: 2012 Model: Boss

  • This will fit a boss, a tune will be needed to prevent CEL.

Mac24 Year: 2012 Model: GT

  • 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 Year: 2011 Model: GT

  • 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

    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!!

    Just when I thought my car couldn't sound any better, I was pleased to hear the sweat symphony of these off road x pipes. I highly recommend these.

    Cheap and fits great

    I was happy with the price, it fits very well and had no issues installing either. My only complaint is, it sounds very hollow almost like you always have an exhaust leak, rather annoying but wouldn't detour me from purchasing it again.

    1st mod on my gt

    I bought the x pipe and the sct tunner with the ghost cam tune. My car is stock other than that and it sounds like I have the roush axel back. Love the raspy note that the x pipe gives and the lope from the tune. It also picked up a bit of power that you can feel and the power comes in sooner thanks to the tune. This is a must have mod for a mustang.
