Loud Aggressive Sound. Add a touch of Borla excellence to your GT Mustang with an "ATAK" catback exhaust system. A Borla "ATAK" catback system will significantly increase exhaust flow over the restrictive stock exhaust system for a dramatic increase in horsepower and an aggressive muscle car sound that is not for the faint of heart.

ATAK. Acoustically-Tuned Applied Kinetics, is Borla's newest technology that produces the highest available dB (decibel) levels to pump the volume while retaining clarity of sound, avoiding distortion typically found in louder exhausts.

Street or Off-road Use. The Borla ATAK Cat-Back Exhaust X-Pipe bolts up directly behind the stock catalytic converters making your Mustang 100% smog-legal. Or it can be installed with Borlas XR-1 Long Tube Headers, deleting the stock cats for even more power making it perfect for off-road use.

High Quality Construction. Constructed from ultra smooth mandrel bent 2.75" stainless steel tubing to improve exhaust flow the Borla catback exhaust system features two race inspired "ATAK" mufflers with 4.5" polished stainless steel slant tips for aggressive sound and impressive looks.

Application. This Borla ATAK Cat-Back Exhaust System with included X-Pipe has a versatile design that allows it to fit 2011-2012 GT Mustangs equipped with either the stock manifolds or aftermarket shorty headers installed. Or it can be installed on 2011-2012 GT Mustangs with a set of Borlas XR-1 Long Tube Headers by deleting the catalytic converters.

Installation Note. When installing this X-Pipe/Cat-Back kit on a BOSS 302 Mustang you will loose the functionality of the factory Side Exhaust pipes.

Tech Note: By removing the catalytic converters, this exhaust is no longer legal for use on pollution controlled motor vehicles and will be intended for off-road use only.

This catback is loud! Just the aggressive sound I wanted. Just can't help accelerating with this new baby. Took me about 3 hrs to install on a lift with the help of my buddy. Not too loud in the cabin. ...

I have the Roush Axle-back currently, how much louder is the Borla compared to them?


  • Hello! While we don't have an exact measurement, the Borla is going to be significantly louder than the Roush Axle Back. We rank the Borla ATAK at a 5 out of 5 in loudness, and the Roush a 3 out of 5.

Will the x pipe that comes with the borla atak system bolt right up to the bbk longtubes


  • The X-Pipe that comes with this Cat-Back is designed to fit with the Borla XR-1 Long Tube Headers (11-14 GT, BOSS), item # 29022, (http://www.americanmuscle.com/borla-lt-headers-1113gt.html). You will have to delete the catalytic converters in order to install these Headers. You may need to make some modifications if you plan to install the BBK Long Tube Headers since they are not designed for each other.

How far past the rear Valance do the exhaust Tips stick out? I have a 2013 Mustang GT Premium. I bought the Roush Axle Back exhaust and had it installed at the dealer. The tips stick out 3-4 inches past the rear Valance. This to me does not look good so I am looking to change exhaust. If anyone knows how far this system sticks out I would appriciate it.


  • I have a Borla S-Type on my Boss and my wife has a Roush axle back on her 13 GT Premium. The Borla exhaust tips, easily, stick out farther than the Roush tips. However, in my opinion, the Borla tips look much better since they are 4.5" in diameter. They really do fill the cut outs on the rear valance perfectly. But if you want the tips hidden more, then this system isn't for you. I had a Magnaflow Competition catback on my 12 and the tips did not stick out very far. There is considerable drone however with that system as opposed to the Roush or the Borla.

    Review from Borla ATAK Cat-Back Exhaust - Black Tips (11-12 GT)

    Top Notch Exhaust

    Exhaust system is awesome...is my second time using an after market exhaust but this one in particular is my number one. You can definitely feel the exhaust now as you romp on it. The volume IS controlled with the gas pedal. It sounds aggressive from the start and screams nasty like a beast. I gave it 5 stars on volume. The price is a little steep for the majority of us, but you do get what you pay for.

    greatest exhaust ever

    All I can say is outstanding job Borla, it is just like other reviews say tamed when cruising but when you get on it all hel breaks loose and there truly is no drone well worth the money

    Borla ATAK Catback

    The installation of this Borla system took a little less than 2.5 hours. The fitment was perfect, and the sound difference was drastic to say the least. I would 100% recommend this product for anyone who wants the "muscle car" sound and growl. I also see a noticeable difference in my acceleration , especially in 3rd gear. Bottom line , great product!

    Borla ATAK Sounds Awesome!

    I love my Borla ATAK exhaust system. I've had it on my car for about 10 months, and it is great. The sound is full, but not too loud in the cabin. Spend the extra money and go with a Borla catback.

    You won't regret it.

    Be smart and save yourself the heartache of going with any other exhaust system. This exhaust sounds AMAZING. In the cab, it's only loud enough to feel good. Crack the windows and you can hear all the amazing. Stand behind it... LOUD! Everyone on the sidewalk will snap their neck in half trying to see you WOT down the road in 2nd.

    Borla greatness

    I love this borla atak! Quiet around town and coming into the neighborhood, slight growl when you start but when you stomp on the pedal everyone knows your coming. Absolutely no in cabin drone whatsoever. This was exactly what I was looking for quiet for normal driving and loud as can be when u stomp on it! Can't wait to buy the borla headers to complete the system. Love the sound, clean welds. Only reason it got four stars for fit is I had to bend the brackets on the axle back to have them set in my exhaust hangers and I had to reuse my stock clamps.

    Perfect system real American Muscle

    This system is perfect for a loud aggressive sound. I love waking up in the morning and hearing this bright and it early. Caution though it will wake the neighbors. I can't wait to install the XR-1 long tube headers to go along with it.
