Video Transcript

Myself and the rest of the video team here at CJ's have worked hard to give you as many different 2015 exhaust videos as possible. Then when you're deciding what exhaust system you want, you've got a lot of different sound clips to make sure the sound is exactly what you're looking for.

The most recent system we installed is the Borla S-Type on my 2015 Mustang GT. So far I've got to admit, it's probably my favorite sounding exhaust system. Ever since we installed it, the number one comment we're getting is what about the Borla Atak?

The Atak is Borla's most aggressive sounding exhaust system and a lot of you are wondering how it's going to sound on the 2015 Mustang. Today we're going to answer that question by installing the Borla Atak Cat-back on my 2015 GT.

Well, the name Atak obviously sounds aggressive. It's actually an acronym. It stands for acoustically tuned applied kinetics. What does that mean? Basically these mufflers are deigned by Borla to be as loud as possible and to keep that loud volume through the entire RPM range.

They actually designed the Atak muffler specifically for each vehicle it's engineered for. The Atak Cat-back system is a two and half inch system leading through a set of Atak mufflers with four inch polished tips.

The entire system is man-drilled bit and features an ex-pipe in place of the heavy factory resonator. The entire system is a bolt-on and no cutting is required.

We'll start of by giving you some stock sound clips then we'll get to installing our Borla. For this installation we're going to need a lift or a jack and jack stands, 3/8 ratchet, 13mm shallow socket, 15mm socket, 8mm allen key, 6 inch extension and a flat blade screwdriver.

Like we've shown you many times in the past, removing the stock system is actually quite easy, but we do suggest a second set of hands to make it easier. The first thing you want to do, remove the two bolts for the two rear brackets.

Don't worry about removing the bolts. They actually have little hooks so they're not going to fall off. Now we'll move forward and loosen the clamps that hold the resonator to the front pipes. You want to bend this tab up. There's a little stud that will stop it and slide the clamp down.

You can pop these little hangers off here. Now the weight's going to go forward and you sort of shimmy the system forward off the rear clamps. We'll remove these clamps off the factory pipes. First we're going to install the factory clamps back on the factory pipes. We're going to start the installation of the Borla Atak by putting the new X pipe up in the place using the factory clamps.

Now you want to snug those up. Don't tighten them all the way, just get them snug. Now move onto the tailpipes. Before we install the tailpipe we want to put a clamp on the connection of the X pipe side and then reinstall the factory hanger as well.

Just hang that for now and move onto the muffler. With the muffler, put the clamp on first. What you want to do is put it up into the rear hanger, just kind of behind the valance. Now go back through, adjust and tighten down our clamps.

Then repeat the process on the other side. The last step is to install the screws in the factory tailpipe hangers. Your installation is finished.

All right, let's see how the Atak sounds. The Atak is as advertised. If you're looking for loud and aggressive, this definitely does the trick. Like I said, the big thing with the Atak is that it keeps the same kind of volume when you're driving under load. Let's take it for a ride and see how it sounds.

I know the Borla Atak is a system a lot of you guys have been waiting for. As far as the sound, like I said, it's as advertised. It's loud, it's aggressive. Even in the car, when you get on it you definitely hear it. I'd say it's every bit as loud as the MRT with the Roush we tested earlier which at that point was probably the loudest exhaust we've had on a car.

As you mount the Borla though, right now I'm at 2100 RPM cruising on the highway, you don't even hear it. No drone, no nothing. It's almost like a stock exhaust. You get a little bit of a deep tone, but literally you can barely hear it on the highway. Down shifting it on it, totally different story.

I'm probably two miles from CJ's right now. I have no doubt they can probably still hear me. It's funny, cruising in fifth on the highway, we're like at three grand, you hear it. It's nice aggressive sound. You can really hear the tone. Sixth, gone.

This is definitely a system that you could cruise all day on the highway and have zero problems. If you want to make some noise, downshift away. I'm on the highway now, right at two grand on the nose where a lot of your mufflers are going to show the worst drone possible.

Here, barely can hear it. There's a little bit of a deep tone if you listen for it, but you honestly, it barely sounds different than stock.

Sitting in idle it's also pretty quiet. You can hear the exhaust, but you kind of have to listen for it. You hear a little bit of a low deep sound, but nothing like the MagnaFlor or other one's we've heard. It's also pretty quiet in idle, but it's nice good sounding tone to it.

The current system I run on my car is the Borla S-Type and I would say the Atak has a similar tone to the S-Type. It might be a little raspier, but it's most definitely louder.

What can I say? The Borla Atak is as advertised. It is loud, in your face. As far as the Borla systems go, it is definitely the most aggressive. It sounds kind of like the S-Type, just a lot more volume. If you're looking for a loud, aggressive, in your face exhaust system, the Atak is going to be a perfect choice.

Like all Borla systems, the fit and finish is top notch. The installation's pretty straight forward. For more exhaust videos for your 2015 Mustang make sure you subscribe to our YouTube channel and check out for the best selection of 2015 Mustang exhaust.

This product will fit the following Mustang years:

Rated 5 out of 5 by from Got mine! The pipes showed up today, put my grubs on soon as I got home. Backed the car up on my ramps which gives plenty of room to work, and I am Bills size :). That being said I was done in less then a half hour using my 18 year old as a tool monkey. Car sounds pretty awesome, will probably save gas short shifting in Best part at 70-75 on the highway there is no drone at all, put your foot in it though and you will probably upset your neighbors off. Stay tuned....JLT and tuner should be here tomorrow.

Rated 5 out of 5 by from Easiest install. Great sound! I installed the Borla cat-back ATAK on a 2016 Mustang GT with the GT Performance package in about an hour. Bill's online video install and review sold me. OEM exhaust came out easily on my one week old GT. Installation of the Borla was straight forward and an easy one man job. The sound is phenomenal. Exactly what I wanted. Thanks CJ Pony Parts for a great price, free shipping and fast delivery.

Rated 5 out of 5 by from Aggressive System I just installed this a few days ago. A friend and I did it in the driveway with a jack and jack stands. It took a little over an hour with adjusting the new system to hang just right. Its a Bill says "aggressive". I wasn't expecting the cold starts in june to be as loud as they are honestly. It tones down in about 30 secs or so though, not sure how long it will take in the winter. The system is quiet when you want it and very aggressive and loud when you need it to be as well. This is definitely a head turner now as the stock system just didnt fit the cars features.

Rated 5 out of 5 by from How the car should sound After hearing that first bellow as you turn the car over you know you've made the right choice. Maybe louder than I thought it might be and a slightly heavier right foot these days but I know this is the perfect exhaust for my car. That being said, maybe my neighbours are not quite as happy about the new addition as I am.

Rated 5 out of 5 by from Exactly what we wanted As much as we love the sound of Flowmasters, we did not want the cockpit noise that come with Flows. Borla Atak have a "take no prisoners" sound on the outside and no drone inside. We're hitting the road this year in our '16 GT - they'll be moving out of our way...

Rated 3 out of 5 by from Quality fitment for ease of installation I just installed the borla ATAK 2-1/2" cat back and I am not happy with the tone of the exhaust, it is extremely raspy at WOT.

Can you get a the ATAK Muffler to fit a 1997 Mustang Cobra, I have headers, x-pipe, and it has a vortex supercharger, love the ATAK sound

Asked by: mustang peter
Borla does not offer a cat-back or axle-back for the '97 Cobra that uses the ATAK mufflers. So you would have to get a pair of ATAK universal mufflers and have something custom made up by a local exhaust shop.

It is compatible for a European Mustang GT?

Asked by: Adrià
This exhaust will fit the European Mustang GT but it will not include any paperwork for US certification. The ATAK exhaust is louder than the legal limit for certification.

Hey guys, I don't know, what exhaust I should get for my GT5.0 Mustang 2017. I'm thinking about Corsa cat-back Sport with 4-1/2" Black tips or Ford Performance by Borla Cat-Back Sport with 4" tips. please let me know what one I should get?

Asked by: bobgi
Selecting your exhaust is something that is very personal that we cannot give you an answer on. This is why we have made a video of nearly every exhaust combination available so that you can hear them and make an educated decision. What I can tell you is that if you have narrowed down your search to these two systems, you cannot go wrong with either one.

Compared to the corsa extreme, how much louder would you say the extremes are compared to the ataks if you could scale it somehow? Also which is your personal preference?

Asked by: Rodrigo
The Corsa Extreme and Borla ATAK are definitely in the same territory in regards to volume, but they both have totally different sounds and tones. As far as personal preference, you cannot go wrong with either one.
