Review & Installation Video

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 live in California, Would this exhaust be legal and pass smog? 1 answer

This Borla ATAK Cat-Back Exhaust will not alter the catalytic converters or their positions and therefore is legal as far as emissions are concerned. The ATAK is a rather loud unit, and depending on your local sound ordinances this may or may not be legal. We would recommend speaking to your local municipality regarding any sound ordinances currently in place.

Can i use this to my 2003 V6 mustang ? 1 answer

To use this Borla ATAK Cat-Back Exhaust on your 2003 V6, you would need an x-pipe for your Mustang. We carry the Pypes Off-Road X-Pipe, item 20006, and the Pypes Catted X-Pipe, item 20040, which will allow you to use a GT exhaust on your V6. You will also need the Pypes Exhaust Hanger Kit, item 20020, for the additional exhaust piping and you will also need to make the extra hole in the bumper for the exhaust tip. https://www.americanmuscle.com/pypes-9904-v6-or-xpipe.html https://www.americanmuscle.com/pypes-9604-v6-cattedxpipe.html https://www.americanmuscle.com/pypes-9904-stainless-hangers.html

Does this come with catalytic converter or no? 1 answer

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.

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?????

2003 Mach1 Borla Atak

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
