Will the xpipe fit fine with the stock over axle pipes or will I have to make some changes or anything?

darkshadow17

  • This x-pipe will work with the factory over axle pipes as long as the pipe has a minimum of a 2.75" diameter.

Tune required? Is a tune required for the engine to run properly after a mod like this since it gets rid of the cats?

OneBadFourSix

  • Yes, for the engine to run properly, especially up to potential, a tune would be required unless the down pipes were not used (as this is of course a modular system). Even in that case I would still highly recommend a tune. A custom Bama tune will be the one thing that brings all your mods that bang for buck.

What clamps should be used to connect the cat delets to the x pipe since the kit comes without clamps? I was wondering if I'm going to have to go buy clamps from a muffler shop to attach the cat delete pipes to the x pipe since I want to go with a offroad set up. I want to avoid welding in order to switch back to a catted setup for when inspection time comes around.

Kaleb828

  • Kaleb, Youll need to gently remove your factory clamps and reuse or purchase new from dealership as that is the style clamp that is used. I ran the cat delete, factory mid pipes with resonators and kooks axlebacks with the ghost cam tune and it sounds sick. Use caution, with an agressive axleback or muffler delete ie Pypes/Rousch etc. Its gonna be loud. Hope this helps.

    Leaks at flange, had to weld

    Product does not come with the clamps for the connection you can see in the picture. We reused the factory clamps as others suggested and it leaks badly. The alignment is terrible and we had to weld that joint up to get it to seal.

    Easy install

    Very straight foward install did mine on some jack stands in the garage with a simple set of tools. Only down sides I had at all are that the box they came in was shredded by the time in made it to my porch and the problem everyone has when dropping the cats, a reaaally long extension to come in through the engine compartment on the passenger side cat. Sound super aggressive with my cat back flowmaster outlaws.

    My God...

    First of all, I just want to say thank you AM for such a great item. Second, don't do this at home, especially when your car has more than 50,000 miles on it. Those bolts for the cats are RIDICULOUS to get off! Take it to a shop. They got it on a lift and replaced the cats and x pipe under an hour for only $75 bucks. Easy peasy. Still with stock manifolds and my MBRP race series catback, I was giddy like a school girl every time I got on it. This thing screams!!!!!! My Stang was basically saying, "I'M ALIVE YOU BUMS!! HEAR ME ROAR!!!!" Haha but seriously, this is a great mod to have on. Once I spun all the way in 3rd gear. I couldn't believe the power added with a Race tune. Don't hesitate, just buy it!!! Thanks AM!

    Not too shabby

    I was going back and forth about putting the cat deletes on, then I decided to do it. The car sounds great, loud and like an American muscle car should. Too soon to tell about power gains, but initial runs feel like it's breathing better. Not a bad inexpensive upgrade. Install wasn't bad, hardest part was getting the factory cats off the manifold, especially the RT side. They're hard to reach. P.S. buy new clamps... if you're planning on using the factory ones, especially cats to x pipe it's difficult to get them off with out destroying them. Better to just get new ones.

    Love the sound

    I purchased these so I could get more louder/raspier sound and I got what I asked for. I was going in expecting that I would get a loud drone at highway speed. To my surprise that wasnt the case. After installing the tune i feel the difference in performance. No drone at cruising but nice roar at WOT. Couldn't ask for a better product. Mods Steeda 101mm cai Muffler delete JBA Xpipe Bama Tune

    Needed additional parts

    Be prepared to bust some rust off of your cats and mid pipes to get this on. It took me about 5 hours from start to finish. The stock cats were, in a word, difficult to work with. The infamous passenger side cat especially. Even with the proper tools to reach through the engine bay, I had to swap impact guns to break the nut off of the bolt as it fried my first gun. JBA dropped the ball and didn't include any new nuts for their bolts, so I had to utilize the stock nuts for the cats. Getting all of the rust off of those was less than easy. Aside from Ford consistently setting me back, the pipes are alright. The X pipe doesn't fit quite right with the intermediate and getting the stock clamps off of the cats was, in my case, impossible. This pipe doesn't come with new clamps, so I suggest picking some up before you take it to the shop. After the installation with the cat delete included, there's a bit of rattling from the poor fitment, but nothing that some work can't solve. The sound is something to be reckoned with. Do the work right, and you'll be turning heads left and right. Overall, this is a good product.

    Fit perfect

    After reading the many reviews about the pipes not fitting I decided to test my luck with it anyways. I did have to do minor adjustments to get a good seal but I did not have to purchase any other products for this. Installation took less than an hour and it sounds great.

    Great sound - OK Fit

    X-Pipe came packaged well. No instructions but it's easy enough to figure out. You'll use your stock gaskets, they provide new hardware for connection to the OEM headers, and you'll need to cut off and reuse the clamps from the factory H-pipe to down pipes. The sound is, of course, awesome. No drone with GT500 mufflers and factory resonators. 4/5 stars because the fit wasn't terrific, but for the price, it's hard to beat. I used some copper sealant between the X-pipe and down pipes and it sealed up for the most part. Overall, I'd buy them again.

    JBA x Pipe

    Decent product if you do not intend to use the provided cat deletes. the construction is good, but the cat deletes to x pipe connecting is vey bad with the stock clamps that are recommended by JBA, I ended up getting aftermarket band clamps and they still leaked. I could only live with the leak for 2 days and have no re installed the factory cats which has stopped the leak. if you want an off road set up look at another product

    14 GT love the sound.

    Looked at this x-pipe for a long time before going for it. Straightforward install and I'm no mechanic so if I can do it most anyone can. Took most of a Sunday afternoon. Hardest part was taking off the stock cats. Only because of the way the factory has the bolts facing up whereas you have to have one heck of a long extension for the passenger side cat. It does help to have someone handy to help hold things in place when tightening things back up. No leaks and I reused all stock clamps. Went with GT-500 axlebacks and this setup sounds strong at idle but not obnoxious. But.......when you hit the throttle instant racecar just add track!!!! Couldn't be more happy!!!!!

    X-cellent x pipe

    I was skeptical to order an o/r pipe for my 2011 mustang gt. I have gt500 mufflers installed and with this x pipe the car sounds amazing. I was worried it would be too loud. the quality of the part was much better than the pypes x I was looking at.

    Product sounds good!

    I love the fitment and sound of this XPipe, it also looks mean under the car, however reusing the clamps from the factory will cause a leak. I took apart and resealed 3 times but it still leaks a little. I am probably going to have to take it to an exhaust shop and have it welded unfortunately! other then that no complaints!

    Not To Shabby

    Had this installed at local shop for less than $70. Did not have any complaints from the mechanic about the fit. I already had Pypes Pype Bomb axle back, and using this X pipe with the factory cats still installed actually lessened the drone I had experienced. Still sounds good and throaty but less scream more thunder. Only complaint is caused by UPS due to how they handle packages causing yet another damaged pipe. Shop had no problem fixing the dent in the cup.

    Does not fit

    The xpipe is just sitting in the box at the house. I tried too install and found out that it would not fit. It would have been very easy too install, if whatever reason it won't go on wasn't a issue. I then brought it too a shop that I've brought all my cars too for custom welded exhaust. They tried and could not get it too go on as a direct bolt on out of the box. Prior too them trying I advised them not too bend, fabricate, or weld. Just try too get it on as is and it wasn't happening. They said if they did put it on that they would of had too weld it because of fitment issues that would of occured, it would of leaked. I did not want that so decided too contact AM. I got a response, but haven't have the situation come too a conclusion. I just want a refund and keep my exhaust how it is. Now my factory Hpipe is leaking and lost $95 on paying the shop too try too put it on. I just want too leave it alone. I'm beyond happy with the flow master outlaws. No point in trying something else and having more problems. Or lose more money.

    Great quality fitment could be better

    I just installed this after work in my shop and I absolutely love it. It took me about an hour to get it in and then another half an hour trying to seal the leaks at the cat delete to x pipe. The fitment could have been better the cat delete to the x pipe was a poorly designed ball and socket joint and leaks. I would suggest getting 3" band clamps to seal it better. I have a roush axel back and airaid CAI and this made my car sound like a beast. It doesn't drone too bad but I haven't done much highway yet. Other than that it is a great product and well worth the price.
