      • Loud Aggressive Sound
      • "ATAK" Race Inspired Mufflers
      • 2.5" Mandrel-Bent Stainless Steel Tubing
      • 4" Polished 304 Stainless Steel Tips
      • Fits 1999 to 2004 GT, Bullitt and Mach 1


      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.

      High Quality Construction. Constructed from ultra smooth mandrel bent 2.5" stainless steel tubing to improve exhaust flow the Borla catback exhaust system features two race inspired "ATAK" mufflers with 4" polished stainless steel slant tips for aggressive sound and impressive looks.

      Application. Designed as a direct bolt on, this Borla ATAK catback will bolt straight up to the factory Mid-Pipe without any modifications required on the 1999 to 2004 GT, Bullitt and Mach 1 Mustangs.

        I couldn’t be happier with the results! I installed this myself and it only took about an hour. I’m a technician by trade so that may not be the same for everyone but I assure you it’s a breeze. The sound is deep but not muffled. And climbing RPMs is a BEAUTIFUL THING! I highly recommend this to anyone in the market for a little more attitude out of your pony

        Had to rent a pipe expander because the pipe with the muffler was the exact same size as the pipe with the tip on both sides

        The absolute best sounding exhaust for your 4.6

        This exhaust is paired with BBK shorty headers, a Pypes catted X-pipe, and a Comp Cams XE274H. I finally had the chance to drive through a tunnel after installing the exhaust. The reverb sounded amazing at low RPMs, but the downshift and following lead-foot unleashed a sound that can best be described as 10,000 demonic trumpeters angrily blaring their trumpets as loud as possible. However, without cats the exhaust is unbearably loud. Totally recommend running at least high flow cats with this exhaust.

        The pipes arrived in a box that was ripped up. The pipes were nice. The fitment was great on the driver side passenger side was not bent correctly, have to take car to muffler shop to get them fixed. A. M did nothing to correct the problem after I called an told them.

        Borla ATAK

        I have an '02 SN95 GT Convertible. It was completely stock and the exhaust was my first upgrade. After doing some extensive research in Roush Performance, Corsa, and Borla, the ATAK was the clear choice. It has a highly durable stainless steel construction and is far better than some of the competition. The people at Borla really know what they're doing. After narrowing it down between the Borla Stinger and the ATAK, I went with the ATAK. It has a wide open, deep, punchy sound. And it is more than enough to satisfy your eardrums when you open the throttle. AM prices are competitive and shipping is fast. Would highly recommend a CAI and increased throttle body at a minimum to let your 4.6 really breathe and open up.

        I love the ATAK's on my 2000 GT. Install took close to 3 hours...recommended to SOAK all bolts and clamps in wd40 to help loosen when removing old exhaust. We did need to cut the old exhaust in half cuz it was on jack stands. Its a deep raspy and I love it! Like always, awesome product from BORLA.

        Everything this car needed for years

        Great fit, great look and sound. In a convertible it is loud. The reviews are no joke. However it has the sound and tone that we wanted. Great growl at startup. Rumbles through the RPMs as you change gears. It settles out around 55 to 65 when cruising along. A bit of a drone after 65 but tolerable. Pushed this decision off for the last 10 years. Old exhaust was in great shape and was sure I want to give up it's classic sound. However this became the one and shes got that tone now that make people turn their head. The product is awesome and the install went as documented by American Muscle.

        Third time charm

        1st time I installed the SLP Loudmouth behind headers and catted x pipe. Interior drone was loud and I could have lived with that. Sounded good at idle but above 3500 RPMSthe sound was loud and scattered, It didn’t sound like a tuned motor. 2nd time I removed the Loudmouth Resinators and I nstalled Magnaflow FT mufflers. Interior drone was low and at idle and higher RPMS sounded good, but too much like a gt just off the showroom floor. 3rd time I installed Borla ATAK. Interior drone is moderate and at idle it’s deep and throaty. At higher RPMS it’s loud but not scattered, it compliments the the work I put into my motor. It does set alarms off anywhere not just parking garages.

        Borla Atak

        To start, I recommend doing the installation on a lift if you have access to one to make it much much easier for yourself. If you do not, it is possible to do but it is more difficult. You will need to life the vehicle up roughly 4-5 feet on jack stands in the rear due to needing to curve the exhaust over the rear axels. Other than that, the rest is simple because it bolts right up to factory hangers and comes with the hardware and clamps to attach the catback. Took only a few hours to complete in removal of the old and install of the new. The sound is like no other when paired with a V8 motor. It's astonishing how loud it is in person opposed to videos online. They give a good demonstration as to how it sounds, but in person it is a whole new ball game--at idle, when in different gears, and revving the engine all sound fantastic. At high revs, it does have a little rasp but that's a given when it is as loud as it is. If you are looking to wake you neighbors each morning with a sexy cold start, this is it. Or wanting the whole block to know you by the sound of your car, this is also the one. The price may be high for some, but I guarantee you will not regret the purchase.

      Alright, I have a 2001 Cobra, will this fit? The only reason I ask is because I swapped from the IRS rear end and replaced it with a solid axle. Similar to the GT models, I’d need it to go up and over the rear axle. Thank you.

      • Considering, fitment wise, you have a GT in regards to your rear end/suspension, these would indeed it.

      Can you guys do an updated video about the system with the sound decibel readings? Literally the only thing stopping me from buying is not knowing if it’s too loud for California. I’m sure others would appreciate it too.

      if i bought this exhaust system and the bbk o/r x pipe would it bolt directly to long tubes or shorty headers

      • This set up was designed to be a bolt on to your stock mid pipe, and may require further modification to fit another brand's x-pipe.

      I have the Borla Atak cat back on my 2002 4.6 GT with the stock mid pipe. How much difference in sound would I get by changing to a Magnaflow catted tru x pipe.

      • The Magnaflow X-pipe will make the car overall have a deeper sound.

      Does kit come with new bolts or do you have to use the original bolts from the factor catback?
