    Review & Install Video

    The Borla long tube headers are going to be a good option for someone looking for a set of stainless steel, one and three-fourths-inch off-road headers with a natural finish, and that don't mind paying a little bit more for this quality. We'll talk more about this later, but I can tell you right now that long tube headers make for a difficult install. So I'm going to call this one a three out of three wrenches on the difficulty meter. Long tube headers offer a few benefits as modification. You get both sound and power gains from a set of long tubes. But of course, your current mods and your build plans will impact your exact individual results. These headers are made from one and three-fourths-inch mandrel-bent, 16-guage, 304-stainless steel, and it doesn't get any better than that material-wise. The stainless steel has this natural finish, which isn't going to change a whole lot over time, and it makes for one of the best looks in the engine bay, in my personal opinion. This finish is going to be different than a chrome or ceramic-coated header. It obviously doesn't have the polished appearance that a chrome header would have. While these don't have a ceramic coating either, the 304-stainless steel is going to hold up really well in all cases. Other than the general construction, the header flanges are three-eighths-inch to help prevent leaks and give the headers some strength. The primary tubes then merge down to a three-inch collector, and that's where these headers end, because they're designed to be paired with a matching Borla three-inch cat-back. If you have or you plan on getting a Borla three-inch cat-back, you're all set with these headers and the cat-back. But just know that you don't necessarily have to have the Borla three-inch cat-back if you want these headers. Just know that they can also be installed with any two and a half-inch cat-back as well, either factory or aftermarket, as well as you have Borla's intermediate adapter pipes, which are sold separately. When it comes to price, you're looking at spending close to the $1,300 mark for these headers. Like I said earlier, Borla products are a little bit more expensive than some of your other budget-friendly options, like Pypes or BBK. But just know that you're getting quality with this brand. You're getting the 304-stainless steel and the benefit of a great-fitting product. At the same time, though, if this is a little bit out of your price range, there are a handful of options that cost a little bit less. Just be sure to pay attention to materials and sizes. As for the install on this one, long tubes are always going to be a difficult install. I don't say this often, but if you don't have a helping hand or you don't have much experience, it might be better to just take the car to a shop for the install. If you do tackle this yourself, it's going to be a whole three out of three wrenches on the scale and a day in the garage, especially considering you'll be installing a cat-back with these headers. You can do it on a jack and jack stands, but a lift would make your life easier for sure. You're going to need your toolbox for this one, with an assortment of different sockets, wrenches, and extensions. You're looking at things like disconnecting the steering shaft, dropping the starter, and removing a motor mount. A lot of this install obviously requires working in some pretty tight areas. So while everything is straightforward, getting access and maneuverability in these areas is actually tricky, which is why you need to pull a motor mount on one side, so you can raise the motor slightly with a jack to give you some more room. Having a helping hand in this case is really going to benefit you, but a day of wrestling and some pretty pennies spent on these mods is totally worth it in my opinion. That's going to be it as far as my review for the Borla long tube off-road headers. But as always, you can check them out more online right here at

    More Horsepower And Torque. Improve the performance of your coyote powered S550 GT Mustang with a with a set of Borla Long Tube Off-Road Headers. These Borla Headers will greatly improve your 5.0L Mustangs exhaust flow over the restrictive stock manifolds for an increase in horsepower and torque throughout the entire RPM band. Significant increases in rear wheel horsepower have been seen when installed with a matching Borla 3" Cat-Back System.

    Quality Construction. Borla Long Tube Exhaust headers are CNC mandrel bent from 1-3/4" 16 gauge aircraft-quality T-304 stainless steel tubing for strength and unrestricted airflow. They feature one piece 3/8" header flanges for added strength, leak-free performance and an OEM style fit.

    Recommended Upgrade. To realize the full power potential that these Long Tube Off-Road Headers have to offer, AmericanMuscle recommends a Bama custom tune with a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation.

    Application. These Borla Off-Road Long Tube Headers are specifically designed to fit the 2015-2017 GT Mustangs equipped with the coyote 4 valve 5.0L V8 engine and a matching Borla 3" catback exhaust system part numbers 140629 or 140630. It is required to re-use the factory metal gaskets when installing these headers.

    Application Note. Even though these Borla long tube off-road headers are designed to work with Borla's matching 3" catback exhaust systems, they can also be installed on OEM Factory, Borla 2.5”, or other aftermarket 2.5” exhaust systems with the addition of Borla's Intermediate Adaptor Pipes part# 60566 - sold separately.

    Will I be able to make some modifications to make these fit with any type of H pipe along with the 3” Borla Atak catbacks?


    Will these long tube fit with a 3" magnaflow competition cat-back exhaust?


    • The Borla 1-3/4 in. Long Tube Off-Road Headers will only work with 2.5" aftermarket cat-back exhausts.

    I would need a custom mid pipe? Or can it be possible to fit my ford performance xpipe?


    • The Borla 1-3/4 in. Long Tube Off-Road Headers will not work with the Ford Performance X Pipe. These headers require the Borla Stinger S-Type 3 in. Cat-Back Exhaust or Borla ATAK 3 in. Cat-Back Exhaust. You can also use an OEM or 2.5" diameter mid pipe by utilizing the Borla Long Tube Header Adapter.

    I have Ford performance sport borla axle back with the Ford performance x pipe delete will this fit?


    • The Borla 1-3/4 in. Long Tube Off-Road Headers will not work with the Ford Performance X-pipe no. When doing long tube headers you will need to get a matching shorty mid-pipe. I have the link below to what you will need.

    Will these headers fit the Ford Performance by Borla Sport Catback Exhaust (Item #384388) without any modifications or extra parts? Not sure since it’s Ford performance Catback but by Borla like these headers. Thanks


    • These headers will be able to work with the FPBB Sport cat-back without modifications as the exhaust was a collaboration with Ford and Borla. The products are made to work in unison.

    I have the Borla Atak 2.5" Cat-back. Would my best option be to get a 3" X pipe to match the headers, or are there other options? Id like to keep as much of the Cat-Back as possible while accommodating this header.


    • Your best bet if you want your 2.5 inch catback to be compatible with the Borla 1-3/4 in. Long Tube Off-Road Headers would be to purchase the Borla Long Tube Header Adapter. This adapter will be compatible with 2.5 inch exhaust so it will work with your 2.5 inch catback. I will post the adapter below:

      Best exhaust on the market

      This is the best sounding headers matched with Borla's 3" cat back system. If you love the sound of muscle cars or race cars you will not be disappointed with this system. The power gains are huge with a custom tune over 50 horsepower gain to the tire. Borla is the only exhaust I would ever put on any of my mustangs.

      Your neighbors will hate you

      If you're looking for a quick power and low-end torque then these headers will provide that along with a beastly roar. Granted, I do have the Borla ATAK 3" cat-back exhaust as well. The install was difficult because I used simple jack stands and there were some tight spaces to get in to, which made the install that much more difficult. Set a weekend aside just in case you run into problems. Most important of all though, take your time.

      Power and sound!!

      These headers paired with a 2.5" ATAK system definitely deliver the low end punch to wake up the Coyote (and every neighbor within a mile). The exhaust note and volume are vicious and it feels like the car is going to rip a whole through space. If you are looking for just a little rumble and better sound, these headers are not for you. But if you want pure performance and be heard for miles around, this is what you want. Make sure you have this system professionally installed, it will save you a lot of headaches and frustrations.

      happiness in a box.

      If your looking for sound I highly recommend these headers. Borla name speaks for itself. I have the atak 3 inch catback with borla headers and my gt is insanely loud. I actually feel bad for the people in my town when I drive around at night lol. I even had a random person follow me for about two miles just recording pulling out from red lights lol. Install was a bit of a pain spent the better part of a day on just one bolt because of the way the tubes run. Borla instructions are straight forward and easy to follow but I recommend a shop install if you can afford it. It will save you a lot of curse words.

      More power and volume!

      Overall it was was worth the price and install cost that came with it. Paired this with the Borla Atak 3in for an even louder and better exhaust note and yes, more power. My stang was transformed into a beast. Not to many cars out there that will sound better or louder. The headers really woke up my 5.0, saw significant gains in hp and torque on the dyno. Definitely worth it.
