More Horsepower And Torque. Improve the performance of your 5.0L coyote Mustang throughout the entire RPM band with a set of Borla Long Tube Headers. These Borla Headers will greatly improve your 5.0 Mustangs exhaust flow over the restrictive factory manifolds to increase your Pony's horsepower and torque. Significant increases in rear wheel horsepower have been seen when installed with a matching Borla ATAK 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 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 Headers have to offer, AmericanMuscle recommends a Bama custom tune with a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation.

Required Upgrade. The Borla XR-1 Long Tube Mustang Headers will require the use of a Borla ATAK, Borla 'S' Type, or Borla Touring system with included X-Pipe for proper installation (See drop down option above).

Application. These Borla XR-1 Long Tube Headers are specifically designed to fit the 2011 to 2014 GT and BOSS 302 Mustangs equipped with the 4 valve 5.0L coyote engine.

Technical notes. Not legal for use on pollution controlled motor vehicles; intended for off road use only.

Oh okay! Is there anything to turn off the rear O2 sensor then to turn off the Cat Code? Thanks!

  • You will need a tuner to disable the rear O2 sensors.

So I currently have the Borla atak catback exhaust system, I am curious to know if there is any way of passing emissions with these Headers? I live in Nevada and they do computer tests here. I really want these paired of with what I have now!

Borla Exhaust I already have the Borla ATAK, axel back exhaust. I want to upgrade to the Borla long tube headers. What components do I need to complete the Borla exhaust system?

SLJ1

  • This, also best thing to do is pair it up with a borla h or x pipe. Depending on what sound you go for depends on what you get. YouTube has alit of good sound combinations

    Borla xr-1 longtubes

    Took about 8hrs total to install. I did mine by removing the k member. Gives you alot more room to work. Instruction well there might as well be none. If you've wrenched on cars before this should be no problem. Tuned on the dyno with hp tuners netted 414.4 whp and 395 foot pounds of torque. Only mods is the longtubes and full borla catback.

    Awesome!!!

    I had my mechanic install the headers for me as well as the catback borla atak exhaust system. It took a full day to install everything. So I had a full day full of suspense of hearing and driving my mustang GT 2014. But all I needed was to start the car and hear my Stang ROAR and I loved it. Driving back home I loved my exhaust even more. Getting looks and people cheering my car on. Thanks American Muscle, this is a great product.

    Great quality and great performance

    Although these headers are more expensive than most brands, the build quality and fit more than make up for it. Unless you have the patience and the tools (i.e. lift), I recommend that you have these installed by a pro. They had to drop the k-member to do the install properly. I installed these with the Borla x-pipe (cat delete) and the Borla catback system with s-type mufflers. The sound at idle is fairly loud, but aggressive. The sound at full throttle will make the ground shake. The headers, x-pipe and catback system with tune definately added power. I have not had a chance to dyno the car yet, but will shortly in the future. Great product!

    Loud, Proud, and WOWED!

    Oh boy. These babies are LOUD. I already had a Borla S-Type catback but these bad boys just scream. Cruising on the highway they sound about the same but a little deeper... but as soon as you touch the throttle is sounds the gates of h*** are opening. Needless to say, I'm a fan. I don't currently have cats anymore, my county doesn't require emissions as of now so if you go that route, it will smell a little different without the cats and backfire here and there... which I get a little chuckle out of.. and did I mention it's loud? Now, on to installation. Hubbah! These took me and a buddy about 2 8hour days in my garage. I used jack stands and a few man powered wrenches and sockets. Getting to some of the bolts on the stock headers were a pain in the butt. The "instructions" that Borla included were a joke to say the least (it basically tells you to go to a shop), and they sent me the wrong bolts for the new headers... the threads weren't the same to bolt to the engine. I had to remove the battery, the starter, cross member, my airbox, the steering shaft, both motor mounts, and jack the engine up. The driver side went in without any issues, the passenger side was a pain in the but because of the air conditioning unit. But nothing that someone with a bit of know-how can't tackle. I will say that bolting these on vs taking the stock ones off are WAY easier. Do I recommend? Yes. Just make sure you leave yourself plenty of time and get a tune.

I am no mechanic and installing these was a pain! Overall, the fit was great and as always the cars performance was greatly increased. waiting to put her on the dyno next month. Thanks A.M

    Great product

    Overall awesome product, great welds nice even bends. Does not come with manifold gaskets, it suggests you reuse old ones so depending on your mileage I suggest that you get some new ones before starting to prevent leaks. You wont need o2 extentions they will reach you just need to disconnect the little retainer at the top of the transmission. Comes with all new hardware but you only need to use some of it on pass side. This is a difficult install my friend and I are experienced technicians and it still took us about ten hrs. Well worth it all in the end, the sound is incredible with the Borla S-type cat back. So loud it set off car alarms as we were leaving the shop.

    Nasty Indeed

    I am running these headers with the matching Borla off-road X-pipe, LTH over-axles, into Corsa Extreme axle backs. VICIOUS and MENACING!!! The power is there and the setup breaks necks left and right 24/7, so make sure you want to wake the dead.

    All I can say is, WOW!!

    These headers along with the 3" cat back exhaust system from Borla make one heck of an upgrade. I took these to the shop to have them installed due to not having access to a lift. It is a very intensive install and unless you are very savvy and have all the right gear, this should be done by professionals. That being said, I picked my baby up and as soon as I started her up, I knew that I had my monies worth. The sound is just great, nothing compares to Borla's quality and they have proven once again that they know how to make a Mustang sound mean. Also, these are a bit pricey, but the guys at the shop said that due to the excellent fitment, I was saved about 200 dollars in labor. The price is well worth it in my opinion.
