    More Power. The Borla ATAK Split Side Exit Cat-Back Exhaust is a great way to improve the horsepower and torque of your 2014-2018 5.3L GMC Sierra. You'll see improvements in both performance and fuel economy as well as get that aggressive, throaty Borla roar.

    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. The ATAK muffler uses a multi-core straight-through design with both perforated stainless cores and ceramic material to absorb high-pitched sounds.

    High Quality Construction. Manufactured from ultra smooth mandrel bent T-304 stainless steel tubing to improve exhaust flow, this Borla catback exhaust system steps down from a 2.75-inch inlet to dual 2.25 outlets. The two included race inspired "ATAK" mufflers feature 4" chromed stainless steel tips that are embossed with the Borla logo for both impressive looks and great sound.

    Installation. Verify that all parts of the kit are present prior to beginning installation. Once complete, follow all instructions carefully. Check your exhaust system after the first few hundred miles and re-tighten any clamps that need tightening.

    Million-mile Warranty. Borla warrants its products to the original purchaser of record and for the original vehicle on which the product was installed, against defects in materials and workmanship for one million miles. That's 20,000 miles/year for 50 years! Some exclusions may apply, please see manufacturer's warranty for details.

      Love it

      Install was very easy, done without a lift. Chose to jack up the back end by the tow hitch just for a minute in order to get the few more inches I needed to angle the old pipe out over the axle. The new system goes together fast and while the instructions aren't totally clear, the way the pipes are sectioned you really can't get it wrong. The new hanger for the second pipe took a few more seconds of thought as to where it went, but looking at where the new pipe was once it was positioned, there's really only one place for it to go. Total install excluding clean up, probably 90 minutes. Sound is excellent. Cold starts are very loud and I don't need my 2 way remote start to tell me the truck started ok. That statement hold for my 4th floor work office as well. If you have close neighbors, this is going to cause friction if they sleep with the windows open and you get out early. After the idle settles down it's well mannered as can be until you get on it. Around town it doesn't stand out much if you don't want it to. Where it really shines is under heavy load. Going WOT up a hill is my favorite thing about this exhaust.

      Borla atak split side

      The Borla atak Catback exhaust was really easy to install, it took less than an hour with all the hardware in the kit, it really improved the sound of the truck it has a deep rumble sound that is not too loud. I would definitely recommend this product to my friends.
