      Review & Installation Video

      Hi Justin with here, checking out Borla’s ATAK series axle back exhaust system for your 2011 and up Mustang GT. The ATAK stands for Acoustically Tuned Applied Kinetics, which is borla’s newest technology, this allows for maximum decibel levels without sacrificing sound clarity. The kit is constructed from 100% stainless steel, and features 2 and 3 quarter inch mandrel bent tubing, two ATAK style mufflers, and twin 4 inch polished tips. Simple bolt on installation that should take you no more than an hour. Let’s hear how the Borla ATAK series axle back sounds compared to the factory exhaust. (Exhaust sound clips)

        This exhaust is by far the best sound I’ve ever heard. Installed on my 2011 mustang GT/CS, and completely woke it up. Truly how a mustang should sound. 10/10 would recommend this product. Loud when you open it up, but perfect rumble as it warms up. When you go full throttle it is just music to your ears!

        Perfect Tone

        I bought my 5.0 used and the previous owner had some aftermarket mufflers installed. It sounded ok but there was a lot of drone and rattle in the cab. My plan is to eventually apply a supercharger, so to start I wanted to open up the exhaust. I first added Kooks long tube headers and high flow cat cross pipes. These definitely opened up the exhaust. You could here exhaust pouring out of the engine. I still wanted more volume from my exhaust! I wanted the loudest I could get out side the car with the least amount of noise on the inside. Any time I heard another mustang with the sound I was looking for I would ask them what they applied and there were many varieties. I would also ask them about the noise in the cab and most of them said the drone in the cab was loud as well. Based on that and the reviews I chose the Borla Attack. I also applied the Borla cat back pipes to make sure I completely opened up the exhaust. This added more to the install which to me is relatively easy, but I do all of my installs myself. I did see a review that commented he wished the alignment out the back was better. He had a shop apply. The alignment is also achieved with the cat back pipes. By rotating the pipes a little you can get your tips perfectly centered. That is another thing I love about these mufflers! The tips look fantastic coming out the back! I got what I wanted the most, when I started it for the first time and heard that growl coming out of the exhaust, it is mean! When you get on it, it screams. I love the sound! When you are on it you can definitely hear it, but when you are rolling down the road, it is much quieter than the aftermarkets that were on before. My wife even commented on how perfect the tone of the exhaust is! It is exactly what I was looking for, it can be really loud or just a nice rumble. I love the look and the sound!

        Great product

        Great product. In comparison to the stock exhaust it is night and day. Sounds amazing i like how it is quiet at idle but when you pass 3k rpm it wakes up big time. Took a bit longer to install than i had hoped because i had little to no equipment practically installed while it was on ground but i did it and i love the outcome. The price was worth it to me i got my bang out of my buck forsure.

        Love this exhaust. It's aggressive, deep, and really turns heads. The 4.5" rolled tips are beautiful and still the bumper perfectly.

        Borla ATAT

        I bought these for my sons 18th birthday. He has a 2011 GT 5.0. He loves them! They are loud but he said that they are fine cruising and he can still hear the stereo. One benefit for me is I can hear how he's driving in the neighborhood. All the way through the neighborhood to the main exit.

      My friend has these 2012 borla ataks. I read that it says these don't fit with the 2013-2014. I ended up installing them and they fit just fine (besides the fact they stick out a little more which looks alright to me). So is there any reason I should not have installed them or?

      • Borla makes this axle back exhaust specifically for the 2011-2012 Models, and offers a separate part number for the 13-14. the main difference is the amount that the tips will poke out past the bumper, with the correct year range sitting where Borla intended. If the tips of your exhaust are sitting where they are not interfering with any body components, and the tips sit somewhere you like them, there is no reason not to use these.

      I purchased my 2011 mustang gt already installed with Roush supercharger. I would like to purchase the borla atak axle back. Would I get same sound result even with the supercharger.

      • The Borla ATAK Axle-Back Exhaust features a loud aggressive sound, so it will definitely be different compared to your set up now. The exhaust tone will simply change.

      Hey, I was wondering if this product would fit a 2012 V6 Mustang. From what I can tell all of the fitments are the same. Thank you,

      • Unfortunately that Borla ATAK exhaust is designed to fit the 11-12 GT models. However, we do offer the Borla ATAK exhaust for the 11-14 V6 model:

      What is the difference between these ATAK mufflers and the ATAK mufflers for 13-14 GT? What is different about the mufflers design/dimensions. The two sets of mufflers appear to be the same?

      • The Borla ATAK Axle-Back Exhaust will vary slightly in the piping included and tip length as the axleback sits slightly further behind the bumper in 13-14 than in 11-12 models. These would not be cross compatible.
