      Review & Installation Video

      Hey, guys. Stephanie with, here with my review of the Borla ATAK cat-back exhaust system fitting all 2015 and up V6 Mustangs. There is no doubt in my mind that the Borla ATAK cat-back is going to be for the V6 owner out there that's looking for a high-quality system that's going to deliver a ton of sound. The ATAK is by far the loudest and most aggressive muffler in the Borla lineup, which also includes the Touring and the S-type. Borla says that ATAK stands for Acoustically-Tuned Applied Kinetics, which is basically Borla's fancy way of saying that this muffler is going to be loud but it's not going to get distorted or sloppy.So a cat-back is obviously going to replace the factory resonator mid-pipe, and Borla does it with their own midpipe resonator, as you can see right here. Now, this is a two-and-a-quarter-inch system, which is the same as the factory system. And this is manual Benz stainless steel tubing. The system is made from T304 stainless steel, which is the highest-quality material that you can get. And it's also been proven to be the best material for exhaust components. Finally, Borla finishes this system with the ATAK mufflers, which we have already sort of discussed.They're one of the loudest options out there and they're paired with four-inch chrome stainless steel tips that have the Borla logo embossed on them, which gives them a nice look under the rear of the car. There also isn't any of that high-end extortion that you normally hear with loud systems. And I think that makes for a very attractive-sounding system for the V6. The system does have some raspiness to it and a crackle or gurgle on diesel as, well as some pops, but it really just reminds me of a GT sound. This is loud, but I think the tuning of the mufflers keeps the loudness from being just noise. And as you guys already heard at the beginning of the video, the sound is certainly aggressive.If you compare the ATAK system to the Touring and even the S-Type, in my opinion, it's more of a higher-pitch tone. I'd say that the Borla S-Type muffler produces a slightly deeper tone. Now, with all of that being said, I'm going to give this a four and half out of five on the loudness scale - with one being a very quiet system and five being your neighbors are leaving notes on your car asking you to only start it during waking hours. Keep in mind that if you ever change your headers down the road, this could open up even more noise for you. So if your biggest deciding factor when shopping for a cat-back is loud, I'd say that the ATAK from Borla is probably going to be the top choice here at AM. If you aren't looking for that loud, then Borla does have other options that I mentioned already.Currently Borla is the only company producing high-end cat-backs for the V6 and naturally they're going to be the highest-priced. All of Borla's cat-backs are in the same price range for the V6, which is right in between $1200 and $1300. There are other options from companies like Mark and Gibson that are available, and on average, those are costing in the price range of $800 and $900. So if the Borla is a little highly priced for you, you can check those out as well, but just know that the quality, engineering, and fitment of those brands is probably not going to be on the same level as Borla, if that matters to you.When it comes to the installer, you're going to be looking at an easy one out of three wrenches on the scale when we look at difficulty. This is considered a direct built-on item, so you won't need to cut anything or modify anything to get it installed. All that you're really going to need is a socket set, and a lift would certainly make things easier, but the job can be done on stands as well. You're going to be removing the exhaust from your resonator back, so an extra set of hands can make things easier for you here. You'll be moving the rear hangers to the new cat-back, so I'd recommend just taking them off with the factory exhaust when you drop that. It'll just make the swap a little bit easier.The only other thing you'll need to reuse are the front cleanse off of the resonator for the front of the new resonator. When you go to install your new set-up, as usual, it's probably going to a little bit easier if you started by hanging the mufflers first. And just in case you're wondering, the cat-back does come with two new sets of clamps for the rest of the system. You can figure on spending about an hour or two from start to finish to get all of this done.To wrap things up with the ATAK cat-back, this is a very loud system, the loudest of the series of three systems that Borla produces, and it doesn't have a drone or any type of sound distortion even in the higher RPMs. It's also a high-quality system that's easy to install and finishes with orange polish tips to give a mean look to go with the mean sound that it produces.I'm Stephanie, and for all things Mustang, keep it right here at

        Great Exhaust!

        I was between the Borla ATAK and the S-Type cat-backs. I ended up going with the ATAK and couldn’t be happier. The exhaust has zero drone, is almost quite when your on the interstate cruising, but when you give the car power it wakes up and screams! The s-type is actually louder at idle than the ATAK but this really comes alive about 2500 RPMs.

        Great product

        Sounds great, feels great, everything is great on it except for the fact that it's only meant for OEM exhaust. If you are also replacing you factory exhaust with headers and a mid-pipe, make sure you ask questions! These pipes will not match up to aftermarket mid-pipe and require extra piping.

        Borla ATAK on 2017 V6

        Hey. Got these in a large box, minor ding on left Muffler. Doesn’t affect sound. 409 stainless looks nice and everything went totherger fairly smooth. Sounds decent, not as loud as I expected, but the sound does seem controlled. It’s nice to have. Will probably get an H pipe made of 409 to go with it.

        Best exhaust you can buy for your 3.7.

        This is expensive, it is, but it is the absolute best thing you can do to your 3.7. My roommate has the axle back version and it does sound good, but side-by-side with the cat-back it doesn't compare. The resonator completes this system. For an even better sound I had a custom after cat H-pipe put on the mid pipe right before where the cat-back bolts up and it sounds amazing. I'm getting shorty headers to complete my exhaust setup, but the tone is nice and deep, especially with the H pipe. I constantly downshift just to hear it rev and the pipes gurgle. Makes me smile every time.

        Have had this exhaust as well as the BBK longtube headers with the off road H-pipe and can not be more happy about my purchase. I’ve had the exhaust for a little over a year and I can say you pay for what you get great product and it definitely wakes people up

        Don't even think twice!!

        I researched and looked up tons of different exhausts, listening to videos and reading a bunch of reviews and none of those can truly show how badass this exhaust really is! I'm not gonna lie to you and say it sounds like a V8 because it doesn't, but if you're looking to take your V6 to the next level with one simple bolt on then this is for you! It sounds amazing and is not to loud to start at night by itself with headers maybe, but great product 1000000 mile warranty you can't beat it, great investment!

        Beastly sound

        I have this exhaust system for about six months and I couldn’t be happier. They were worth the price and they sound absolutely beastly. I refuse to use any other company due to the quality and sound of the Borla. If you want an incredible sounding exhaust with no almost no interior drone than this is the system for you.

      hi, someone cant tell me if a difference in sound exist betwen Magnaflow Competition catback and Borla Atak catback for mustang a V6 3.7l.?

      • Hello! The Borla Atak will be slightly louder than the Magnaflow Competition Catback. For a better idea of the sound differences, we have videos of both of these exhausts on the product page.

      How does the sound of these compare to the Flowmaster Outlaws I currently have on my V6 Fastback, both in terms of rumble and drone? It’s very hard to tell from the videos, and I want to make sure there is significant improvement if I’m going to spend this kind of money.

      • As far as volume, both these and the Outlaws would be on the list for the loudest exhaust we have to carry. However in regards to Drone, Flowmaster is much more susceptible than Borla typically. A good way to ground yourself when listening to sound clips online in my opinion is to take your own video on your phone of your own exhaust as it sounds now. Being as most people just do the same thing and upload it to youtube, listening to your own phone recording of your own exhaust helps lend a solid reference of what the difference would actually be when listening to random peoples' clips online.

      Does this exhaust take time to break-in. Watching the exhaust video on the website it sounds pretty aggressive, but when installed yesterday the sound is pretty lower than even roush exhaust. I mean i expected it to be loud, its one of Borla's aggressive exhausts.

      • There is no break in period for exhaust systems.
