Balances Exhaust Gases. The Pypes Off Road X-Pipe is excellent when it comes to balancing out the gas pressures in your exhaust system. This Pypes off road x-pipe creates more power and torque than a traditional H-pipe. Why? Because the exiting exhaust pulses are merged at the "X", resulting in less exhaust back pressure for more power.

Race Car Growl. This free flowing Pypes x-pipe for the 2005 to 2010 GT's not only increases power, but it also adds a raspy, race car growl to the sound of your exhaust with its modern "X" crossover pipe design.

Modular Construction. Pypes unique three piece modular construction makes it quick and easy to add or remove catalytic converters to your exhaust system in just minutes, depending on your driving needs.

Durable Stainless Steel Construction. Pypes uses sturdy 16 gauge 409 stainless steel mandrel bent 2.5" tubing for improved exhaust flow and features welded reinforcement plates for additional strength.

Application. This Pypes Off-Road X-pipe is designed to be a direct bolt-on for the 2005 to 2010 4.6L GT Mustangs with either aftermarket short tube headers or the stock factory manifolds and a dual catback exhaust installed. Intended for off-road, track use only, does not include catalytic converters.

  • i have an 07 GT and since there is no huge difference in the 05 and 07 models i would say no. my stock O2 sensors went right back into place just like they were.

Does the X-pipes need new O2 Sensos ? or just the one i have on

RayanRitchie Year: 2007 Model: V6

  • You can use the ones you have, you just need a tune to cut them off or your check engine light will stay on.

    WOW. Bought from AM and pipe came in the mail about a week later. INSTALLATION: Had a shop install it, they said the install went great but they had to alter the pipe a tiny bit (bore a hole 1mm wider) to fit the passenger side O2 sensor in it, and that it was a bit of a reach. Not a problem though! Took 45mins to install with one mechanic doing it. Cost me 124 bucks at a high-end muffler shop. Before reading on, consider that I have Pypes Violator axlebacks. They're chambered mufflers, but they're high flow and loud. Not quite straight pipes, but close. Not as loud or raw as Pypes Bomb. LOUDNESS: This is LOUD! driving home from the shop I was scared to even let it above 2000RPM! Immediately turned heads everywhere I went. This is LOUDDD. You can creep quietly through a neighborhood if you have to, but if you need to accelerate.. game over.. haha.. Idle past cops. EXHAUST NOTE: Takes a bit of getting used to! After the drive home from the shop I sort of felt like I rap]ed my GT. This innocent pony was now snarling, screaming and growling as if it's mad at me... wasn't sure I loved it until I did some driving later that night...I fell in love with the sound. It's a challenge keeping the car quiet driving downtown and in neighborhoods, but I love doing it (saves me gas too, up 2 MPG). As soon as you add power, the raspy sound will come out at any RPM range. with full power, the entire band is LOUD and it opens up at about 2000, from 2000 to 3500 it gets a bit raspy, but as soon as you get it over 3500 it turns into a beautiful smooth tuned race sound. I love merging onto roads and watching other drivers faces when they hear it.. Oh, and when you start it up the hairs on the back of your neck will stand up. The sound itself is raw and raspy... but not in a bad way.. you can almost hear each cylinder fire, and it seems that having virtually the same flow out of each pipe allows this. If you don't love it at first, you will learn to love it. Goes very well with my violators. POWER: I don't even have a tune for it yet (waiting for tuner in mail) but the car breathes so much better above 4000. It reaches redline much faster. Definitely feel the horses. Pipe makes it sound like im packing 700 of em, too. BANG FOR YOUR BUCK: Absolutely. Everywhere you go, your car will turn heads. Floor it, and everyone in the town will be looking for the source of that great noise. Puts Lambos and Ferraris to shame ;) Girls love it, too. Also note that without the catalytic converters, your exhaust is quite a bit more smelly, and you'll often catch a sniff of it at a light or cruising windows down. Warning: This is loud. Scary loud and agressive. If you don't want your Mustang to sound like a 700hp race car, don't buy it. I hope this review helped! Thanks AM, you guys are the best.

    Great sound

    This is a great x-pipe if you want to be on your neighbors shit list. This system sounds great, especially with chambered mufflers. If you have a straight through pipe (SLP power-flo, SLP loudmouth), you will pretty much be able to wake the dead with this system. It makes your car sound great, and you will notice a horsepower increase in mid range speeds!

    Loud and Fast!

    I just got these installed recently, easy install and man is it LOUD!!! Paired with the Pypes Violator Mufflers, it truly is an awesome sound. Goes faster too, i can definitely feel more the extra Horses. Lol cops liked it too. Only thing is the check engine light due to two trouble from the fact that the O2 sensors picked up more emissions cause of no cats. programmer fixes that easily. It's great, you feel your hairs stand and a nice chill go down your spine when you start it.

    Good Start

    The pipe sounds good, brings out that \"Mustang sound\". At first I didnt like it, but its growing on me. Will definitely require at least an axle-back to complete the sound. NOTE: When installing this, you will have to remove the battery and battery tray to access the top manifold flange bolt on the passenger side. After you remove the battery and tray, also disconnect the wiring harness for the front O2 sensor as you will have to drop it with the stock H-pipe. These little hints are not in the instructions.

    Pypes off road X-pipe

    Lets start off by saying i got this part in a day and a half. what great service. Thanks AM!! Now about the product. It came nicely packaged and with instructions and stickers. looked great in the box and was pleased with the quality and price of the x-pipe. install wasn't hard if you have some experience. the hardest part was the removal of the old cats and h-pipe. After that install went great. Fits like a glove and had no problems installing. After the race tune from BAMA was installed the first start up was shocking!! This x-pipe was installed with the factory headers and Pypes Pype-Bomb axle backs. What an awesome sound if you like old school muscle car sound. It's just like a race car. Its a little raspy when the system is cold but sounds great when it warms up!! I turn heads every where I go now. As someone else said on here( Its Wake The Dead Loud). Thanks AM and BAMA!! And Thanks to PYPES for a great product at a great price!!

    Very Loud

    This x-pipe is extremely loud, worth ever penny. Your neighbors will just love you in the morning when you crank up your mustang. Great product, I would highly recommend this along with the Pypes muffler delete set up. I have them both on my 05 GT and let me tell you I turn heads every where I go. I've had cops pull me just to hear me rev up, chicks love it, and those guys with the classic stangs out there show me much respect.....its a beast let me tell you. Pics coming soon, I've been a customer of AM for 5 years now, they got me for life.

    Race track LOUD!

    This is a very loud set up and I mean LOUD! So here's the deal. If you go to the race track or really hate the people you live around then this is the set up for you. If however, you use your pony as a daily driver as I do, save yourself a few bucks and just get the X pipe. I installed the off-road system with my violator mufflers and it was just way too loud and raspy without the cats. I re-installed the cats and just the cut and clamp x-pipe and was very pleased with the result. Sounds better and you can feel the mid range power increase. Less drone then the stock H-pipe. Install was very simple with basic hand tools and mechanical skills. It took me about an hour and a half without a lift. The x-pipe looks better as well for those of you that like to look under your car alot!!

    Want that snarly race car sound? Go no further.

    I'll start off by saying that this system is loud when combined with the Pypes Pype-Bomb resonator tips, but in the best way possible. Any where from creeping through a neighborhood and letting your pony snarl at others, or letting it rip in the 3000+ RPM range on the main roads, you won't be disappointed. This combo is a major head turner, and nothing but compliments have came my way since installation. With the Pype o/r x pipe and the Pype-Bombs combo, you will see a side of your stang that you never thought could have existed. Sounds like a race car if pushed hard, but settles to a deep snarl when going light on the pedal. Install time was about 2.5 hours for both the x pipe and the Pype-Bomb resonator tips, mainly because the stock mufflers were such a hassle to take off, other than that it was all bolted on in an hour or so in my garage. As for power, I noticed the main difference climbing at 3000 RPMs, and I assure you that the new found horses are certainly not shy when putting that pedal down. Buy it and listen to it growl.

    Pypes O/R X-pipe

    This product is awesome, and has a very loud tone between 1500 and 3500 RPMs. Product was well wrapped when I received it. I took my time installing it. I put it on a lift at an auto skills center on a air force base and paid $24 for the time I spent putting it up. The pain was getting my rusted factory H-pipe off but I used some liquid wrench penetrating oil and let it sit and finally got it off. Once I put this x-pipe on It was time for business. Loaded up a bama tune to balance everything out and I was tearing up the streets. First drive to the store I had people turning heads. Amazing product and great service from AM.
