    Hear and Feel the Roar. Borla's Dual Rear Exit ATAK Cat-Back Exhaust will add Borla’s super aggressive ATAK sound to your 2014-2018 6.2L GMC Sierra 1500. With Borla’s Mandrel-bent pipes and straight-through and multi-core technology, you don't need to compromise fuel economy for increased performance.

    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 3.5-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.

    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.

        I have a 2017 silverado with a 6.2l Vortex engine with an 8 speed automatic transmission. I was wondering if there had been any tests ran with this exhaust system and this type of engine package operating in v4 or 4 cylinder conditions?

        • Unfortunately, we do not have any access to Dyno results with this setup. We would advise to reach out directly to Borla as perhaps they have run studies on this. You can reach them directly here at:

            Review from Borla ATAK Dual Exhaust System - Rear Exit (14-18 6.2L Silverado 1500)

            2015 Silverado High Country 6.2L

            I purchased this Borla ATAK exhaust and the KandN Blackhawk cold air intake together. Both of them together unleashed a beastly sound I was unaware my truck could make. Hardest parts of this install was the removal of the factory exhaust which I ended up cutting in 3 pieces and lining up the left side exhaust. Advise for future installers: if you have a tow package on your truck make sure to use the frame bolt closest to the front of the vehicle for the left side exhaust hanger. Also make sure to put all of the pipes on the left side together before attempting to hang the exhaust tip. Overall was not a bad install and well worth the purchase. Sounds ridiculous on cold start and when accelerating but mellows out nice at idol or maintaining speed.

            Best exhaust to go with.

            I’m really glad I pulled the trigger on this system. It sounds great. I’ve alwys seen the trucks with the dual outlet and one side is not level with the other but this kit was perfect. When you fire it up I think everyone looks for a corvette. I have had only good complements.
