    Loud Aggressive Exhaust Note. The Shelby GT350 and GT350R already arrives from the factory with a very aggressive driver selectable multi-mode exhaust system, but that's just not good enough for some people. It is for those select GT350 owners that Borla designed their ATAK Cat-Back. Featuring a set of acoustically tuned dual-mode ATAK mufflers for a loud aggressive tone, this Cat-Back includes an X-Pipe cross over that adds a crisp, raspy race car growl to the sound of your GT350's exhaust. Together this combination will be sure to be heard for miles around.

    Increases Power and Performance. Borla's ATAK Cat-Back Exhaust will not only wake up your neighborhood, but it will also wake up your 5.2-liter Voodoo engine as well. By upgrading the restrictive factory piping to ultra smooth mandrel-bent 2.75" tubing, along with a set of high flow straight-through ATAK mufflers, you will significantly increase your GT350's exhaust flow. As a result of this increased exhaust flow you will see a dramatic improvement in horse power, torque and engine performance.

    ATAK Technology. The included mufflers were engineered using Borla's ATAK (Acoustically-Tuned Applied Kinetics) technology. Delivering the highest dB (decibel) levels possible for a street legal muffler, ATAK mufflers are tuned like a graphic equalizer to shape and focus sound waves for optimum high-volume output, all while avoiding distortion and retaining clarity of sound. ATAK mufflers are ideal for those hardcore Mustang enthusiasts who prefer to hear the sound of their exhaust over the sound of their stereos.

    Compatible with Factory Multi-mode Exhaust. One of the coolest selling points of the Shelby GT350 and GT350R is the multi-mode exhaust that allows the driver to select between normal and sport modes. Knowing that this was one thing that no GT350 owner could do without, Borla designed their mufflers with the same style butterfly valves as Ford. In the closed position the valve blocks the exhaust flow, forcing it out one tip of the muffler to produce a more street friendly sound. When opened the valve "uncorks" the exhaust allowing it to exit through both tips of the muffler to generate an aggressive, throaty race style exhaust note. This Borla ATAK Cat-Back reuses the factory valve motors.

    High Quality Construction. Borla manufactures their exhaust systems from high quality 304 stainless steel tubing for superior strength and enduring corrosion resistance. Featuring ultra smooth mandrel bent 2.75" diameter piping and a set of straight-through ATAK mufflers, this Borla Cat-Back will significantly out flow your Shelby GT350's original factory exhaust system. This Cat-Back reuse the factory exhaust tips located in the rear valance.

    Direct Bolt-on Upgrade. Borla's ATAK Cat-Back Exhaust with X-Pipe bolts straight up in the stock location with no cutting or extra modifications required. Installation of this Borla Cat-Back can be completed in about two hours with just basic hand tools. This ATAK Cat-Back reuses the existing factory hangers and electronics for installation.

    Application. This Borla ATAK Cat-Back Exhaust with X-Pipe is designed to fit the 2015-2019 Shelby GT350 and GT350R Mustangs equipped with the Voodoo 5.2L V8 engine. Will not fit GT models.

    2018 GT350 Mustang. 1) I don't like the factory exhaust note, too brappy, had a 14GT with Ford Perf Pack-perfect sound. How does Borla compare to factory GT350 sound wise. 2) I don't want louder, simply deeper sound. Any way to get system with S or Touring muffler instead? 3) I added a CAI to my Pony-no tune required. Will I need to tune her if I add the Borla to my package? Let me know-wife willing to spend $$ as she doesn't doesnt like sound either-I need to get on order before she changes her mind!!! Thanks

    • This exhaust will be louder when compared to the stock exhaust but it will also be deeper and more aggressive. If you have the active exhaust system, this is compatible with it to where you can use the quiet mode to lessen the volume. Unfortunately, at this time, we do not carry the Borla S type or Touring but you will be able to switch out the mufflers separatelyif you do decide the ATAKs are too loud or if you don't like the sound. You will not need a tune when adding this exhaust to your setup and will work with the stock tune.

    Could I retain my active exhaust feature with this kit? I’ve seen ATAK setups with the active exhaust feature before. Just curious if this one will still work the same.

    • Yes, the Borla ATAK Cat-Back Exhaust for the 15-18 GT350 models is compatible with the active exhaust.

    Why will this exhaust not fit on the GT models? The GT350 ARH Cat-back system fits on the GT.

    • The Borla ATAK Cat-Back Exhaust has a specific design for the GT350. We cannot guarantee proper fitment on a GT.

    Is there an estimated horse power gain with this exhaust?

    • Doing a cat-back or an axle-back will not really increase the power of the car. You may see a few horsepower but this is manly for sound. If you really want to up the power you will want to check out long tube headers!

    Would this exhaust work on Mustang V6?

    • This system will not work on the V6 models due to the difference in size. Now we do have the Borla Ataks for the V6 models but these would be single tips only.

      Borla exhaust

      The new exhaust is deafening louder than the factory exhaust but not what I was going for because of the higher pitch sound; I like the loud deep aggressive sound.

      Sounds amazing

      I got this before I actually got my GT350. I got the car home from the dealership and had this on the next day. The sounds this thing makes on a car are incredible. It definitely makes the exhaust quite a bit louder, but by retaining the active exhaust it allows you to have a quiet exhaust when you start you in the morning so you don't wake up the entire neighborhood. I would compare "quiet mode" to a little less than sport mode on the stock exhaust. Sport mode is LOUD. With the windows up it's really not too bad inside the car, so it's still reasonable for long road trips. I HIGHLY recommend doing this install on a lift. If you don't, it's going to take you 2-3 hours from start to finish, a good chunk of which is going to be lifting and lowering the car. Overall it sounds incredible, and after you let it break in for about 500 miles or so, you start getting the crackles and pops and (surprisingly) even more volume. If you want an exhaust that will turn heads everywhere you go and sounds amazing, this is worth every penny.
