    Top Acoustics. Get better acoustics by upgrading from your 2014-2018 5.3L GMC Sierra’s factory exhaust to the Boria ATAK Cat-Back Exhaust. This dual rear exit system features ATAK (acoustically tuned applied kinetics) technology for Boria’s highest available decibel levels. The aggressive exhaust note maintains clarity, even at higher volumes.

    Premium Materials. Boria’s ATAK Cat-Back Exhaust is crafted from high-quality stainless steel for a long-lasting system. The exhaust is custom made for your truck, featuring multi-core technology, straight-through design and 2-3/4-inch mandrel-bent piping to optimize volume while flowing into the muffler and out through dual 2-1/4-inch pipes into 4-inch round, angle-cut, rolled-edge tips. Performance gains and better fuel economy await you with this roaring exhaust upgrade.

    Bolt-On. Boria provides all parts and hardware for the installation, from the perforated tube muffler to the clamps, hanger assembly, and heat shield reflex wrap. Follow the detailed instructions in the kit to bolt on the system with dual split rear exit. Boria backs this tough-looking exhaust with a warranty against imperfections in material and workmanship for one million miles from purchase date.

      Review from Borla ATAK Dual Exhaust System - Rear Exit (14-18 5.3L Silverado 1500)

      Borla ATAK 2017 Chevy Silverado LTZ 5.3L

      Decided to bite the bullet without being able to void any dealership warranty’s. By far great investment to upgrade. Noticeable overall performance improvement aswell a nice rumble cruising down the street! Didn’t have a lift so had to jack up and make due with cutting original exhaust to get off. But install was fairly easy with a extra pair of hands and once you get past the rubber mounts. Highly recommend this to anyone contemplating on upgrading for performance.
