      Review & Installation Video

      Hey guys, Adam here with Today we're taking a closer look at, listening to and installing our Borla ATAK Axle-Back Exhaust for the '13 and '14 GT and the '13 Boss 302. Now, if you're the owner of that 5.0 and you're looking to beef up the sound of your 5.0 to give it more aggressive tone and a much louder volume, this is a great way to go without distorting the tone. Now this one in particular, as you heard from our sound clip is gonna get the full five out of five on a loudness meter, that's just how Borla rolls with the ATAK. Now, ATAK or Acoustically-Tuned Applied Kinetics is made to give you the higher volume without distorting the tone and we'll talk a little bit more about that later on comparing it to factory. Know that this guy is gonna have a deep throaty idle and get a little bit raspier at the top end when you get to wide open throttle.Top end absolutely screams, it's got a very loud bark, but it's not gonna have the most ridiculous drone inside the cabin thanks to that ATAK technology when you're on the highway. So, that's one of the bigger bonuses here with the ATAK system compared to other five out of five loudness meter exhaust systems. The other thing that's cool about this is three or four stainless steel, 2.75-inch mandrel bent tubing, four and a half inch polished stainless steel slash cut tips, all of which are top quality materials, the best you can get in the category which is what we expect from Borla. Now, axle-backs, in general, are more affordable than a full cat-back. So, you should look at this if you're not looking to spend the big bucks on a full cat-back for your 5.0, but instead, beef up that aggression while saving your wallet some of the hurt. Now, this one comes in right around 900 bucks and the install I'm going to give two out of three wrenches on our difficulty meter. It's just a little bit more involved than say a cold air intake, right? You have to take off the brackets right above your mufflers to get this thing uninstalled. You wanna have very simple hand tools and know at the end of the day, there's no cutting, there's no modifications, no welding, it is a direct bolt-on. Now, I'm gonna take you guys through every step of the process starting with getting our factory mufflers out of place. So, what do you say we get started? Tools used in this install include an impact gun, extension, quarter ratchet, 13-millimeter deep quarter inch socket, 13-millimeter deep 3/8 socket and a 13-millimeter swivel socket is recommended. PB B'laster or WD-40 is recommended as well as a hanger removal tool. First up here guys, grab a 13-millimeter socket, you're gonna loosen up the ball joint clamp right here connecting your axle-back to the over-axle pipes. Grab a hanger removal tool and you're gonna pop out the factory hanger from the isolator just next to your tip. At this point, you can try to slide your axle-back out of position with the clamp loosened and your hanging out of position. But you may run into the sway bar, some models might be able to squeeze it out, on ours it's a little tight. So, what we're gonna do is actually remove this hanger bracket on the back end of your axle-back. There's one bolt underneath and one on the side there. So, I'm gonna use a 13-millimeter swivel socket and just pull our axle-back muffler out of the way to connect this. Now, on the frame here, there's another bolt, a 13-millimeter right there holding on that bracket. Now, you won't be able to get an impact gun in here but we do have our quarter inch ratchet with a 13 socket. Now, I'm gonna work this off and the exhaust is gonna wanna come down so you can either try to hold it together or have a helping hand just to make sure it doesn't drop on you. All right, now you can disconnect it, bring it all down together. Guys, once you have your right side done, repeat the exact same process on your driver side and then we'll be good to install. All right, so we got our factory exhaust off of our 2014 GT, we've got it next to our Borla ATAK Axle-Back and I wanna show you guys some of the similarities but mainly the big differences between the two kits and really there are a ton. The factory exhaust as you know guys is really going to muffle a lot of that sound. It's bringing down a lot of aggression due to all of the baffling inside of those mufflers. So, it's really not the best for guys who wanna maximize their sound. And the tips coming out the rear, they're nice, they're about 3-inch tips. They're not anything special and they're not really polished too well, so they're not really standing out and bringing a lot of attention to the rear. upgrading to the Borla ATAK changes that completely. The mufflers here, the ATAK mufflers are Acoustically-Tuned Applied Kinetics. That's the technology built in here, hence ATAK, which basically means that they're putting out the maximum amount of volume allowed by a muffler without distorting that tone. Sometimes when you get the loudest of the loud you get something with extremely high drones, very high pitches that can get really overwhelming especially inside of the cabin. The ATAK muffler focuses on giving you that volume, while also minimizing those higher frequencies to give you a really, really good quality, crisp sound. That's why I really go for the Borla ATAK, I really like them when it comes to five out of five on our loudness meter because they focus on that really high tech technology. Now, aside from that you're getting 304 stainless steel through a 3-inch mandrel bent tubing, mandrel bent being a smooth bend in the manufacturing of the tubing to make sure there's no restrictions in that airflow. And 304 basically means it's the highest quality muffler, highest quality exhaust material you can get on the market. If you're located in a wintry weather area, maybe you see a lot of road salt in those snowy months like we do here on the East Coast, then you know that that salt can take a toll on the underbody, especially the exhaust materials. 304 stainless is known to be one of the most durable options in the category. So, Borla is really making premium quality stuff.Out the rear, you're seeing a big change in tips as well. We're going from those factory 3-inch tips to four and a half inch slash cut, really thick walled, polished stainless steel tips. Also, 304 stainless so they're holding up and that polish on top is more of a chrome. It's really reflective. It's got a lot of shine to it, and it's something that definitely stands out in comparison to your factory stuff. And guys, that's gonna make a night and day difference. It's also got the Borla name embedded in that exhaust material on top, not a sticker, it's not gonna burn off, it's in there and it looks really good. The thicker walls give it a more beefy, aggressive look over something as thin as your factory tip. So, even something like that makes a big difference. Now, I wanna show you guys how this gets installed, we are gonna have to transfer over those factory brackets. They're pretty easy, we're gonna put them actually on the car first. The reason we leave them on the mufflers is to make uninstall easy, but putting these in is gonna be a lot easier because the mufflers are actually a lot smaller, the smaller mufflers make this life a little bit easier. So, let's install those on our vehicle and we're gonna take these off using a hanger removal cool. Now, to get these brackets off, you wanna grab your hanger removal tool and you're gonna pop off the one that has this little endpoint. When that guy popped off, the whole thing will slide right out and you can transfer them over. Do this for both mufflers. All right, start here on our driver side, what we're gonna do is take our bracket and they are side specific. So, make sure you're keeping true to what it was when it came off the vehicle. Grab those factory 13-millimeter bolts, I'm gonna thread them in by hand to hold this bracket in place. The driver side has three of them, passenger has two. So, we've got one on the bottom, one here on this top right corner and then another on the top left corner. All right, and there is this little retaining pin that is making sure it's in the exact spot that it needs to be in, so you don't have to worry about it being off at all. Once it's in that spot and the pin is inserted it's good to go, tighten it down with a 13 socket. Now, for this last one, I like to use a ratchet just because it's in a really tight spot here on the frame. All right. Now, we can grab our muffler and the factory clamp to tighten this down. So now we can insert a muffler starting at the hanger above your tip. Using PB B'laster to lube things up and make life a whole lot easier for you. All right, once this one's inserted, go to the back and insert them into the other ones. So, this may be a little tricky but slide your entire exhaust system backward to fit it into these hangers. Now, you can tighten on your clamp aligning your muffler. All right guys, once you have your driver side complete, repeat the exact same process for the other side. That's gonna wrap up my review, install and sound clip for the Borla ATAK Axle-Back Exhaust for the '13, '14 GT and the '13 Boss 302. You can get your ATAK right here at

        Let your Mustang’s voice be heard!

        If you are looking for the system that lets people know your Coyote means business, then this system is for you! I have stock headers, and a 3 inch Pypes X-pipe with these Borla ATAK’s and I absolutely love the sound. These axle-back’s in my opinion are the best bang for your buck systems out on the market!

        Best axle back money can buy

        A coworker has a 2011 gt with 3in exhaust cat and resonator delete with flowmaster outlaw my 2013 gt has stock pipes resonator delete and high flow cars with the borla axle back. The borla is louder at rev and under load and has next to no drone cruising. However if you dont want to wake up neighbors or draw attention the borla atak may not be for you. Wife said she heard me 2 miles away when talking to her on the phone leaving the store.

        Wow sounds great!

        Ok flat out...these are the most expensive mufflers you can buy for this car (axel back). That being said, they are worth every penny. When I cruise through the neighborhood in third gear she sounds tame and reasonable. When I leave the neighborhood and get up to 4500 rpm she roars with a deep throaty sound that makes your heart race as fast as the car. Only one other mod so far, the nighthawk cai from KandN. Took me about 2 hrs to install with just a jack (no stands) because I had to really squeeze under the middle of the car. You need to detatch the mid-pipe to get a clean fit. Had to use plenty of wd40 to get the pipes loose. Over all this is just a plug and play install. I get compliments on the sound all the time. Was worried about the cabin noise but when you are on the highway in 6th gear it’s almost as quiet as stock so the Bluetooth phone calls are just fine.

        Amazing sound

        Couldn’t jack my car up very high (no jack stands) so I had to squeeze underneath and really stretch out to unhook the mid pipes. Plus they’ve been there for 3 years so it took me a little while to break them lose from their fixtures. Took me about an hr and a half to get the old ones off and new ones on as a mechanically inclined first timer. All in all a major sound upgrade. I was a little worried my neighbors would be able to hear it while warming up my car in idle but it’s not bad at all. The cold crank has a nice little roar to it but after the rpms drop back down to the stock ~700 rpm, the car isn’t much louder than stock mufflers. The second you give it more than 2500 rpms however it’s nothing like stock. Cruising through my neighborhood going 25mph in second gear (2500rpm) is just enough to make the neighbors working in their yards take a second look. Same speed in third gear (1500 rpm) quiets her down a good bit for when I leave early in the morning. When I go wide open throttle she screams and man it feels good. I drive all over the east coast for work and when I’m on the highway in 6th gear and need to take a call I can still talk just fine through the cars Bluetooth audio. If I have to take off from a red light it does get a little annoying for the other person I’m the phone but not unbearable. The drone is non existent. It’s expensive but worth every penny. I can tell when I’m driving by other stangs now if they have borlas or some other brand... it sounds so much cleaner. I get compliments whenever I stop.

        Borla ATAK - well worth the extra cost

        ATAK's may be a bit more expensive but high quality and great distinctive note. No problem installing, fairly straight forward.
