      Review & Installation Video

      These are the Borla Over-Axle Pipes for 2011 to 2014 S197 GT and GT500. These are gonna be a good option for anyone looking to upgrade to a Borla X-Pipe and Axle-Back exhaust in stages, and you're looking for the budget-friendly stainless steel option. So an entirely new exhaust system can get expensive fast, especially if you want a nice setup. But there are ways to upgrade in stages. Normally, you get a new set of over-axle pipes when you purchase the cat-back. If you purchase just an axle-back and then pick up a mid-pipe down the road, you're looking at still having your stock over-axle pipes. You only get a new set of over-axle pipes for the cat-back or if you purchase them separately. Borla offers these over-axle pipes as a separate upgrade, so you don't have to purchase a whole Borla cat-back at one time to get new over-axle pipes. For the install, you can plan on spending an hour or two to get it all done, and you can expect a one out of three wrenches on the difficulty meter. The over-axle pipes are made to work with the Borla X-Pipe and Borla Axle-Back. Some people have made them work with other setups, but if you're looking to just bolt these right on and go, then you should already have the Borla X-Pipe and a Borla Axle-Back. Otherwise, if you wanna make these work with something else, you may need to tweak or bend some things to get these bolted up. Looking at the big picture here, the stock over-axle pipes have resonators in them, and they're also kinked which it doesn't help with exhaust flow. So not only are they restricted because they have those resonators, but they're also restricted for flow reasons. Eliminating those kinks and the resonators is gonna open up some sound and performance from the S197. So there's not much difference between these over-axle pipes and the stock ones. There's only so much that you can change there, but the difference is gonna be the elimination of those resonators which would be in the straight portion of the pipe and at the other end. The factory pipe has to flatten out here to fit on the car, and the factory pipe makes a funky S-Type of curve. These pipes eliminate that and the resonators, and you just have smooth manual bends instead, so that's where the benefit is gonna come from. Your sound gains are gonna change depending on the axle-back and mid-pipe setup that you have on your car, so keep that in mind if you decide to change your mid-pipe or headers or axle-back down the road. The sound you get from your exhaust is ultimately gonna change depending on your setup. If you have an off-road setup, it's gonna be louder. If you have a Borla ATAK versus a Borla Touring, it's gonna be a different sound. The over-axle pipes will open up some flow, but, ultimately, the sound that you can expect is all gonna depend on the rest of your exhaust setup. As far as materials, these are full stainless steel pipes, so they're gonna be perfect for all cars, even the daily's that see harsh elements and road soil. Stainless steel is always gonna be your best option when it comes to exhaust components because of its long lifespan and corrosion resistance. When it comes to price, you're looking at spending just south of $350 mark for these pipes. Like I mentioned earlier, the whole point of this product is to upgrade your exhaust in sections, so you don't have to shell out a ton of money for an upgraded system all at once. Some of the top of the line cat-backs are over a thousand bucks or very close to it, and if you pair these pipes with a Borla aftermarket Axle-Back and matching X-Pipe, then you've made yourself a full cat-back, and you didn't have to shell out that much money all at once. As far as the install, it's not gonna be a difficult one at all. You can plan on spending an hour or two to get it all done, and you can expect a one out of three wrenches on the difficulty meter. Your stock over-axle pipes will come out easily enough. It's just a few bolts to loosen the clamps and the mid-pipe and the mufflers to get those out. You'll just need to sneak the pipes out. These pipes will then install the same way that the stock ones came out, and they are side specific, so just be careful there. I'd say to make sure you go over the bolts and retighten everything down once your car has had some run time. You wanna make sure that you avoid any exhaust leaks. All right. Wrapping things up here, these are the Borla Over-Axle Pipes for 2011 to 2014 GT Mustangs. As always, you can check them out more online right here at americanmuscle.com.

        Easy install! Resonator delete is amazing!

        For those wondering if it’s worth it, $350 for little HP gain; NO. But $350 for resonator delete and amazing sound; YES! My car is so loud starting up! Sounds super mean. This gives my Corsa Xtremes and Pypes X-pipe a whole new sound! Loud, mean, and totally worth every penny. Is it stupid loud on the highway or just cruising? NO. It’s nice and normal, but as soon as you put your foot down, it wakes the neighborhood! Will the cold-start make your neighbors hate you? YES, but from jealousy.

        Work great with the Roush Axlebacks

        Got these shipped in quick! I had the Roush Axlebacks on and was a bit worried about if these would fit. Good news is these over axle pipes are a direct fit to the stock fittings, so these ARE compatible with a stock H pipe and other axlebacks. Install wise I tried to do it on jack-stands, but could not get enough clearance and had to drive it to my buddy's lift. If you had tall enough jack-stands you may be able to snake it out, but be careful because it will require a lot of clearance. It took me 45 min to install them with a impact gun.

        Good product

        You need a lift or really high jack stands to install these cause they get stuck on axle in the back.

        Awesome!

        Perfect fit and great sound! If you’re looking for louder.....this will definitely help. And to those who are wondering if they will work on lowered cars...yes. They do. No rattles no interference issues. Nothing. And I’m dropped 1.5” front and rear. Perfect fit and finish!

      If i have a pypes h pipe and borla axle backs will these fit

      • These Borla over axle pipes will work with the Borla axle back exhaust as they are both 2.75" however modification will need need to match the over axle pipe to the Pypes H-pipe as the H-pipe has a diameter of 3".

      Helpful (3)

      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?

      • 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.

      I did a resonator delete on my current set up and my question is would it be worth it to buy this? What would I benefit?

      • These over axle pipes would increase the airflow being pushed out of the car with the larger piping. This would be the only benefit that would have if you already deleted the resonator.

      Why do these OA pipes require a protective sleeve when the stock OA does not?

      • These over-axle pipes are bent slightly differently from the factory pipes. The heat shields are provided as a precaution to avoid any heat transferring to the fuel lines.
