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 this come with catalytic converter or no?

JerardoE

  • This Borla ATAK Cat-Back Exhaust will not come with catalytic converters. This exhaust will not replace your mid-pipe, so you will reuse the catalytic converters you already have.

Will this model fit with ceramic long tube BBK headers? BBK off raid x pipe? For 2002 gt

  • These Borla Ataks will work just fine with the BBK headers and mid-pipe!

Will this system fit with bbk headers part number 56009 and the bbk x pipe 56130? and if anything else is needed for it to fit on an 04 mach 1

JoeyA

  • To use this Borla ATAK Cat-Back Exhaust with the BBK 1-5/8 in. Ceramic Long Tube Headers, item 56009, would require a shorty mid-pipe as the stock length units will be too long for the long tube headers. We recommend the use of the BBK Off-Road X-Pipe, Item 56135, or the BBK Catted X-Pipe, Item 56137 for proper fitment for the headers and the cat-back for your Mach 1. https://www.americanmuscle.com/bbk-fulllengthheaders-99-04-cobra.html https://www.americanmuscle.com/bbk-offroad-shorty-xpipe-9604v8.html https://www.americanmuscle.com/bbk-catted-shorty-xpipe-9604v8.html

i just want to inquire if this catback will work with my macs ceramic long tube headers and macs prochamber xpipe as far as collector size and connections. thanks!

TaylorK

  • They indeed will be compatible together as the mid-pipe is designed to work with stock catbacks and this catback is designed to fit with stock midpipes. So it would be safe to say they will work together! I will link the pro chamber mid pipe below: https://www.americanmuscle.com/mac-shorty-prochamber-9904gt.html

Dose that exhaust can fit with the Kooks LTH

SHA

  • This Borla ATAK Cat-Back Exhaust will fit both the Kooks Long Tube Headers with a 2.5" collector when used with the Kooks Catted X-Pipe, item 66528 or Kooks Off-road X-Pipe, item 65527. Kook's header for the Mach 1's utilize 3" collectors, so these would unfortunately would not fit. If you have a GT and are interested in either the Kooks 1-5/8 in. Long Tube Headers, item 65526 and one of the two x-pipes listed, then this Borla cat-back would indeed fit. https://www.americanmuscle.com/kooks-catted-shorty-x-9904gt.html https://www.americanmuscle.com/kooks-offroad-xpipe-9604gt.html https://www.americanmuscle.com/kooks-longtube-headers-9604gt.html

    Borla ATAK Review

    I installed the Borla ATAK on my 2002 mustang today. Installation wasn't not as hard as what people were telling me it would be. I have not been able to stop driving the car now. This exhaust is one of the best sounding cat-back i have ever heard on a mustang. if you are on the edge about what cat-back to get i would spend a little extra money and get this. you will not be disappointed. this exhaust is the perfect combination of tone and volume. and on the high way it is not annoyingly loud like some other systems. I also never heard a drone while cruising around today.This is by far the best modification i have done to my mustang.

    You will not be disappointed with the Borla Atak. It sounds amazing! It is not overly loud when cruising but trust me it is plenty loud enough when you want it to be. It is well worth the price tag and you will not regret buying this system!

    UK Borla ATAK review

    Spent many weeks trying to decide between the Stingers and the ATAK decided to pay the extra and get the Atak just got the Borla ATAK cat back system installed on my 2004 Mach1 wow very impressive what a sound. Brings my Mach1 to life, this is how the Mustang should sound nice and throaty but not overly loud sounds great when accelerating, pops and bangs when on over run sounds like it has a modified engine. Running stock headers and H pipe JLT true cold air system. No drone just pure muscle car sound have the windows down most of the time listening to that addictive sound.

    borla ATAK

    I went back and forth between the stinger and ATAK at first till I heard the ATAKs in a video clip. Totally worth the 800 dollars! When in idle it's not super loud or anything but you can tell there's a beast waiting to be unleashed! Under hard acceleration it's a higher, more cracking and raspy tone but in a good way. Borla did a great job at tweaking the tone to still sound great. I'm 19 and with some help from my little brother we were able to install it with ramps and a few simple hand tools. The only kinda hard part was getting the porper tool to cut the old exhaust. Took us an hour and 45 min.

    Best V8 exhaust

    Best American v8 exhaust system in the world. A little secret to the raspy sound, get a O/R X-Pipe and no more rasp. I promise gentleman, even a catted X-Pipe would be OK but mek sure it fits your header length. A CAI and tune would be extremely beneficial with this as well

    Borla Atak on a 4.6 2V

    These Borla Atak are very high quality. BE AWARE , these exhaust are very loud, way louder than MAC catback and Magnaflow...you can't go for a long time on the road with these exhaust because the noise gets annoying. The price is also high compared to the other brand.

    WOW!!!!!!!!

    This cat-back is by far the best sounding exhaust i have ever heard, its really loud and raspy but it still has an AMAZING tone to it. Usually these loud raspy exhausts don't have a nice tone and just sound random but this one is different, i have NEVER heard anything like it. The sound my car makes now with long tube headers and an off road x pipe is absolutely amazing, plus the 4 inch tips look fantastic too. Go ahead and spend the extra money on this cat back, you will not be disappointed trust me.

    Great Purchase

    This exhaust is absolutely worth every penny. Great sound quality, it's not too much & obnoxious sounding, very little drone. The only problems that I had when installing was getting the pipe to squeeze over the axle. Once I was able to do that, every thing was as smooth as it could be. Fitment was perfect & you couldn't ask for a better sounding exhaust.

    2003 Mach 1 borla ataks

    Installed in about two hours with one jack stand in a driveway.. The exhaust clamps are far better then other they do not crimp the exhaust so they allow you to adjust length and figment.. First start sounded throaty and angry after a few days of driving after full break in for a catback system it almost sound like full header h-pipe combo.. May be a little pricey at first but deft worth the money I garuntee you guys will not regret the price.. If you truly car about your stand (8 years with multiple years .... Owned 94-95-03 gt-01 cobra2013 5.0) now a 2003 Mach 1 by far the best exhaust note... Very pleased and lots of looks and compliments... Note to driver only driven for two weeks the exhaust deft. Gets the right attention.. Thanks American muscle for such a great product once again.....!

    New Aggressive Attitude

    This had to be one of the most difficult decisions I've made for my 2002 Sonic Blue Mustang GT Convertible. I longed for a much more aggressive Tone. Needless to say, Borla did not disappoint. Even the Technician that installed it told me that the sound was "Very, very nice!" That would be titled Understatement of the year!

    Borla ATAK'S

    As with all Borla products, fit and finish was spot on, the only thing I am not too fond of with this exhaust system is the tone of it. Its too "raspy" for my taste, if I could trade this out for the stingers I would in a heart beat, much more of a deep rumble to it.
