Performance You'll Love. While the stock exhaust system might be enough for some, you can make your Pony sound more aggressive and deep while performing better using these Borla Over-Axle Pipes. When combined with the Borla Rear Section and X-Pipe (both sold separately), these Over Axle Pipes finish off the cat-back system. There's absolutely no drone at any speed, no matter the gear you're in. You'll love these pipes and your passengers will be impressed with how they sound.

Built to Last. These Over Axle Pipes are designed to directly replace the factory ones and are made of high-quality mandrel-bent stainless steel. That means you don't need to worry about them warping or becoming corroded as they can withstand the rigors of everyday use.

Excellent Quality. Borla has built up a serious reputation for making some of the finest exhaust systems in the industry. You can place your confidence in these Over Axle Pipes because they add solid value to your S197 Pony. Their diameter measures 2.75 inches, allowing exhaust to flow freely and your engine to breathe as it should. Borla uses custom tuning to ensure these pipes work great with your specific GT or GT500 Mustang.

Application. Borla engineered these Over-Axle Pipes to work with all 2011-2014 Ford GT and GT500 Mustangs when combined with the Borla Rear Section Kit and X-Pipe to form a complete cat-back system.

Will these fit the 2010 GT500? I did not see the product offered for the 2010 model year.

BenWaller

  • These Borla Over Axle Pipes do not fit on 2010 Models. 2005-2010 models used a slip on design, whereas the 2011-2014 models used a flared ball socket flange.

Will these pipes also replace the resonators or is that a different section of the piping? If not is there a delete kit for my car?

RichardW

  • Hey Richard, Well technically the resonator is a form of muffler, and this system would not replace that. These will be the pipes that connect the mufflers to the mid pipe. so it will not delete the resonator (muffler). To change out the part of the system you would need to go with a axle back, or if you're feeling a bigger change go with a catback and that will be the combination of the axle back and over axle pipes.

Will these fit with the bbk x pipe on 2014 mustang GT?

NickK

  • These over-axle pipes will have a 2.75" diameter whereas the BBK X-pipe will have a diameter of 3". For proper fitment, you will need either a step down pipe or customer modification from an exhaust shop.

    Nothing but the best from this company!

    To start, I questioned whether it would be a good idea to buy these over axle pipes due to some of the reviews on this site. Now that I have them on my 13 GT I couldn't be happier. I had borla exhaust parts on my old 04 GT and the fit and finish was perfect. These over axle or 'intermediate' pipes fit perfectly on my car. High quality stainless steel means minimal corrosion, and getting rid of the factory resonators gave a great new sound to my 5.0. Wouldn't expect anything less from Borla. I am extremely satisfied with this product and will be buying borla long tubes and mid pipe to go along with these and my borla ataks. Nothing but the best when you buy borla exhaust parts!

    Nice addition! Installed on jack stands.

    This an addition for those of us who don't want to annoy the neighbors every time you fire up your pony, but get more when you mean to. I bought these to augment the GT500 axle backs on my '12 GT. I was looking for a bit more of a throaty tone, and previously though I had dented my resonators in the past (turns out, that's a "feature" from the factory). I got what I wanted: throaty, lower rumble at idle, and a nice crackle and pop on downshift. There's another reviewer who complained about rasp - he may have different axlebacks, but these work really well with the GT500 mufflers in my opinion. I do think you're paying partially for the Borla name, but they're fit and finish is top notch, so to me the extra cash is worth avoiding the pain-in-the-a$$ery you can get subpar quality. Some tips on installation: I did this on jack stands, and you'll want to remove the rear springs. It's easy - don't be intimidated (but buy a decent torque wrench): 1. Once on stands, place the jack under the diff (use a block of wood between the two, and make sure it's centered!) 2. Remove the way bar-to-body attachment bolts - be careful, removing the last bolt lets the sway bar pivot down. I didn't pay attention and almost lost a few teeth when it came down. 3. Remove the lower shock bolts. You might have to adjust the jack up/down a bit to remove the strain on the bolt. 4. This is important: inside each fender well, remove the brake line bracket. This gives the brake line enough play when you lower the diff - you don't want to stretch those. 5. Lower the diff - remove springs. Installation is reverse of removal. Here are the torque specs: 1. Shock bolt: 85 lb-ft 2. Way bar bolt: 85 lb-ft You should be able to snake the old pipes out, and get the new ones in now. Be sure to use the red heat shields, and carefully place the pipes to avoid the drive shaft hitting it when the suspension articulates, clearance from wiring, fuel lines, and the body. I was able to get at least one finge width everywhere (although I still fill that's close). Now that I've done it once, I could probably do this in under 2 hours. I'm very detail oriented, so it took me way longer than it should have. Oh, and while you're in there, I put a aluminum drive shaft in. If you do that, be sure to temporary place the pipes (don't attach them, let them hang down), button up the suspension, and install the drive shaft. Access to its bolts is much easier with the exhaust pipes removed.

    They're okay I guess for the price

    Well I bought these pipes thinking that they will look like the picture but I should have read about it first it's a non coded finish... and when I receive them they were all scratched up look like something you get at a exhaust shop cheap but I wet sand them and polish them up came out pretty good....

    Before you purchase...

    These came well shipped, but my mechanic said he had to alter one of the pipes slightly to fit with my roush axle backs. These did make my exhaust louder, however once I get around 2300-2700rpm the rasp is pretty bad. I'll probably end up going back to my stock over axle pipes so I'm out a few hundred dollars. I'm sure that depending on your exhaust setup, that these pipes will make it better but for anyone using these with roush axle backs w/ stock h pipe and cats I wouldn't recommend. THIS REVIEW IS NOT TO BASH THE PRODUCT, only to make people aware that along with a louder exhaust note the rasp will increase. It might be a better idea to have muffler shop cut out your resonators, so if you don't like the sound they can weld them back in. Hope this helps.

    Love these pipes!

    These Borla over axle pipes are the perfect complement to an aftermarker axle back exhaust. I paired mine with the borla s-type and this setup really shows you how great the mustang can sound and how it should have sounded straight from the factory. Installation is straight forward and is able to be done on a pair of jack stands. Highly recommend!

    Borla over axles

    Great option if your looking to delete your resonators. Paired this with the roush axle back, cai, and bama custom tune. It screams on WOT and cold starts. Not obnoxiously load when cruising or idling. Great if you want deceleration pops. I wanted more so I got the bama custom tune and it makes a BIG difference. If you dont want to go through the hassle of a cat delete for sound, go with these.
