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.

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

Will this fit onto a BBK Off-Road x-pipe?

JeremiahM

  • Yes, this borla cat back exhaust system would be a good fit onto a bbk offroad xpipe as long as the xpipe that is currently on the car is a 2.5" exhaust design.

Ok, so here is my question. My 2003 mustang is currently a 3.8Lv6, although soon I will be swapping to a v8. It has a true dual exhaust system already. Will this product be able to go on before I do the swap or will I have to wait?

TylerM

  • We would not be able to confirm fitment of the Borla ATAK Cat-Back Exhaust on a V6 with true duals.

Would you recommend the slp loudmouth or the borla stingers or the atak which one is the best for the money

Cullen1

  • The SLP Loudmouth or the Borla Stinger, and Borla ATAK will all be very similar, making the final decision come down to personal preference on the sound of the exhaust. Performance wise, these Exhausts are going to be all identical to one another.

Recently had the Borla Atak system installed but after having installed i noticed that the passenger side of the exhaust sits very close to my rear tire. Is this normal?

DanielT

  • Hey Daniel, Yes that is going to be a normal occurrence with after market exhaust especially with aftermarket wheels as well if you have them too.

Is there anyway to get the tips in a mat black color?

Ghost

  • Unfortunately, we do not offer the Borla ATAK system with Matte Black Tips. However, you could get them painted, powder coated, or purchase separate matte black tips of your choice.

    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.

    Definitely worth the extra costs associated with the Purchase and subsequent installation. Even the Mechanic that installed it said that the sound was absolutely "nice!" He sells other Brands other than Borla. Very happy with the purchase.

    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!

    Awesome exhaust system from Borla I did the install myself and it was quite simple. I purchased this to complete my long tube and off-road x pipe setup and wow this makes it insanely loud and I love it i wouldn't recommend it for a daily driver but overall great exhaust system from Borla

    It looks and sounds better than stock. The tips really clean up the rear of the car, and makes it sound more agressive.

    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

    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.

    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.

    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.....!

    Always been a fan and supporter of Borla but wow, this exhaust is exactly what I wanted and more! Paired it with the Magnaflow O/R X Pipe and it turns 11/10 heads! The 11th head is the dog/cat that just jumped when i touched the gas. A little louder than my liking but after getting use to I could'nt be more pleased. Love it! Thanks AM for the awesome prices and delivery and support! Worth every penny and more!

    Happy customer

    I researched what exhaust system to buy for years, finally picked this set up, couldn't be any happier with the purchase, is it crazy loud no... but does it make the car perform better than my other configurations yes, I have ran with stock,flow masters, and just manifolds with h pipe, to be honest it sounds like when I had no mufflerservice at all but when your lighting up the tires and you hear it open all the way it has a distinct sound, anyway it's the best looks and sounds good, build quality is at the level I expected witch is very high.

    Borla ATAK

    This exhaust is by far the best cat-back available. I did hours of research to get parts to complete my exhaust system and knew I HAD to have this Borla ATAK for my 02 GT. The sound is incredibly clean and has a perfect tone. Like what other people said it's LOUD when you want it, but can also just be a normal low level growl while cruising around. It fit perfectly with my BBK shorty headers and BBK off road xpipe. This borla ATAK should be on EVERY 99-04 mustang, the looks and sound set it far ahead of all competition!
