    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.

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

    Will this make my car over 95 decibels? I live in California.

    Hey all I bought this cat back and installed it, later I put a bbk o/r x-pipe. Now I remove the x-pipe and threw the stock h pipe with cats back on But the tone is way different then when I first installed it without the x-pipe. Could something happen to the resonator?

    Does it come with x pipe

    • This Borla ATAK catback will bolt straight up to the factory Mid-Pipe without any modifications. It will not come with a x pipe.

      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.

      Great sound

      Went from magnaflow with no cats on my 02 Saleen to this Borla and it is 10x louder. Exhaust fit pretty good. The only drawback was the fittings going to the x pipe aren’t 2.5 like the rest of the exhaust, they are much smaller than the magnaflow so didn’t fit quite as good.

      AWESOME SOUND!

      I paired this cat back with the Magnflow X-pipe and stick headers. The sound is incredible! But the best part is that in 5th cruising down highway or at idle it just about disappears. Dont let this fool you. When you get on it it will turn heads. The only complaint is.....$800 system and you can't include hardware......really?????

      Well, I installed it on my car and it sounds amazing. Quality construction. Had to get a pipe expander for passenger side but it was on $20. After I opened it up everything fit perfect. Get new universal exhaust rubber hangers to eliminate any install issues. Shoot gaskets with WD40 and have a nice day. Love it.

      Worth the money.

      I am very satisfied with the Borla ATAK product. Fit and finish were perfect. Installation was easy. The sound is awesome! This package is more expensive than the others but well worth the investment. Borla has really dialed in the optimum sound effects. Just what I was hoping for.

      Nice and Loud

      Extremely loud, as I paired it with the BBK Off-Road X-Pipe. Sounds great, however would almost say too loud in 5th gear on the highway. Like the rumble when driving down the street but would like a little relief in 5th gear going 75mph.

      Very satisfied

      Very high quality material. Very high quality sound. Although good luck if you have stock headers and replacing mid pipe as well. Passenger manifold bolts are a pain. Also hard installing the ATAK’s on jackstands. Had mine on their highest setting because of clearance issues with the over axel. All said and done not too hard of a job. I definitely recommend this product!

      Mean sounding

      Borla attaks is what you want to go for to wake that 4.6l up. Even with the stock mid pipe sounds nice and mean but I’m going for even meaner with an o/r x pipe.

      Dare to buy the best for your Mustang

      I have had the Borla,Atak cat back for about 2 months .The stainless steel material appears to be of high quality for a long life. The sound is in credibley loud but not obnoxious on occasional drives.. I think I made the best and wise decision in purchasing this exhaust system. Looking for some more great driving experiences
