Borla ATAK Cat-Back Exhaust System with Dual Bright Chrome Tips (140797) - 2014-2019 Silverado / Sierra 1500 5.3L V8
Wake up the high-performance spirit of your truck with the high-impact Borla ATAK Cat-Back Exhaust System. Custom-engineered for 2014 to 2018 Chevrolet Silverado 1500 / GMC Sierra 1500 models, as well as 2019 Silverado 1500 LD and Sierra 1500 Limited (LD) trucks, this premium full-length exhaust upgrade introduces Borla's legendary acoustic profile: the ultra-aggressive ATAK (Acoustically Tuned Applied Kinetics) sound level. Formulated explicitly for driving enthusiasts and performance purists who crave an aggressive, head-turning, and race-inspired exhaust note under acceleration, this system is calibrated to make the high-output 5.3L V8 engine truly roar. This configuration delivers a commanding exterior acoustic presence while relying on advanced straight-through internals backed by Borla's official No-Drone Guarantee to keep the cabin completely comfortable and drone-free during highway cruising, daily driving, or heavy towing.
The internal engineering of the Borla 140797 targets key factory flow restrictions by incorporating an upgraded high-efficiency performance layout featuring a step-down pipe design transitioning from a 2.75-inch inlet to dual 2.25-inch tailpipes that routes perfectly under the truck chassis. This performance architecture utilizes ultra-smooth mandrel bends and patented multi-core internal geometry that maximizes exhaust velocity and optimizes scavenging to unlock hidden horsepower, sharper throttle response, and enhanced fuel economy across the entire powerband. Built completely from premium-grade, aircraft-quality T-304 austenitic stainless steel, this highly durable cat-back assembly defends permanently against structural degradation, intense under-car heat cycling, and severe corrosion. The spent exhaust gases exit through a distinctive dual passenger-side exit layout finished with massive 4-inch round, rolled edge angle-cut bright chrome premium mirror-polished T-304 stainless steel tips. Precision CNC-manufactured for an accurate line-to-line bolt-on fitment, this system utilizes all factory mounting positions and is backed by Borla’s legendary lifetime Million-Mile Warranty.
