      Review & Installation Video

      Borla's ATAK we're working with today for the 2011 through 2014 3.7L-equipped Mustang is a great option for someone that's after arguably one of the most aggressive-sounding cat-back systems on the market today. Installation-wise, you're going to be looking at an easy one out of three wrenches on the difficulty meter here, and we'll talk about that more later. What you just heard will easily warrant a four out of five on the loud or the Wake the Dead or Neighbors, scale here, and it's really easy to understand why. The ATAK changes out your heavy factory cans for a pair that's going to make more noise. But more importantly though, guys, the overall volume and tone won't be distorted or raspy like some of the cheaper systems out there. Now, this is going to be due to the use of Borla's Acoustically-Tuned Applied Kinetics, which basically means that when the volume goes up, it's going to be crisp and clean. But for comparison's sake, this will be a touch louder, higher, and clearer in tone than their S-Type system. This system absolutely turns heads on the street or track. But the best aspect about it, put simply, guys, is that when you want to drive quietly, it will let you. Now, putting aftermarket exhausts on the 3.7L will cause some drone. It's really inevitable here. But the ATAK muffler will also help calm that down the most cruising around, and you're going to find that it's pretty minimal. Now, while it's taking a four out of five on the Loud-O-Meter here, if you're looking to take this even further, you could install an off-road mid-pipe. But that's something that's going to be extremely loud. Aside from plenty of noise, you're going to be looking at some of the best steel available for an exhaust. That's 304 stainless, to be exact. That's great because of its ability to resist corrosion. Now, this will feature two and a quarter-inch ultra-smooth, mandrel-bent piping that's going to bolt right up to your factory piping. All hangers are tacked on and ready to go and the mufflers end in some great-looking four and a half-inch, polished, slash-cut tips, which gives a nice balance of classic meets modern. Last, but not least, they are going to have Borla's logos embossed on each tip, so everyone around you is going to know where you're getting that sound from. With great build quality, that sound, and last, but not least, having the Borla name, expect to be spending over $1,000 to get these onto your car, and that will make this one of the most expensive cat-backs on the website right now. While I know it sounds a little bit on the steep side, there's a couple options from Stainless Works, and even Borla's Stinger or S-Type that will get you almost the same type of build quality. But from personal experience, it's just not going to have that overall sound that the ATAK is going to produce. Installation-wise, cat-backs go on with little to no effort at all, and you should expect a straightforward two hours' worth of labor, which warrants one out of three wrenches on our difficulty meter. Now, tools for the job will call for a pair of jack stands, a basic socket set, maybe some penetrating oil to hit your factory hangers. You'll want to start by getting your car's rear end off the ground. Then, work with unbolting the existing system from directly behind your factory mid-pipe. Moving on, you'll get to the back of the car and remove the axle-back portion of the system. Then, start back at the mid-pipe, throw your mufflers in place, tighten everything down, get your over-axles in there, and then you're good to go. So that'll wrap up my quick review of Borla's ATAK cat-back, fitting the 2011 through 2014 V6 Mustang, that can be found right here at

        They nice

        I’m not gonna lie I feel like I got played For $1000 they sound nice not what i was expecting, maybe it’s because I just got em Installed they used more idk but they aren’t all that. I think if I add a x pipe and new headers I’ll get the sound I’m looking for cause it’s Sounds aggressive when I hit the high rpms but naturally super soft In the lows I wanted that deep tone but it was low key worth the money kinda sorta

        Install Yourself

        Very happy with the quality, sound, and performance of this set! If you are going to install them yourself on jack stands, it can be done but you need to jack up the body of the car, releasing the suspension. You will then need to support the axle, and remove the bolts from the upper sway bar link, and the bolts from the lower shock mounting point (4 bolts total). One side at a time. You can then lower the axle enough to get the pipes over. You might have to remove the rear springs, but they just sit on the axle and can easily be removed.

        Wakes up the V6

        Reaaly makes it come alive... especially as the revs climb. Very mild around town, low rpms open it up and it sings

      5 Top Rated Questions

      CAT back or Axle back? What is the difference difference between getting the cat back over the axle back? HP, Sound, Performance?

      • HP gains are little, there is a sound difference though, axle back sounds sorta cheap whereas cat back doesn't, cat back also add quality to the exhaust and it should be done if you plan on adding headers or a mid pipe later on.

      Any horsepower gain from this set up?

      • The Borla ATAK Cat-Back Exhaust is a lot less restrictive than the factory piping. This kit should definitely help free up some horsepower!

      Popping/Backfire I have seen a lot of YouTube videos of this system and it seems every time they let off the gas there is a popping/backfire noise, I am wondering if that goes away with time? Does it happen every time you let off of the gas?

      • There is a lot of popping and burbling with the ATAK. Each time i shift it pops and if you are at a high rpm and take your foot off the gas it will burble down. i happen to love it but its not everyones taste

      Is it legal in California?

      • The Borla ATAK Cat-Back Exhaust will be smog legal in California. You will need to confirm with your local law agency regarding decimal levels limits.

      I plan on installing the borla atak cat back with bbk long tube headers and bbk catted x-pipe (2011 v6), will I need to buy header gaskets, flange gaskets and doughnut gaskets for proper fitment and for all this to fit together perfectly is there gonna be cutting involved?

      • No cutting necessary, all of the exhaust pieces you mentioned will definitely bolt right up to each other! Being that the Borla ATAK Cat-Back Exhaust and the x pipe in question are designed to bolt onto their stock counter parts, they'll bolt onto each other.
