Borla ATAK Cat-Back Exhaust System with Dual Black Chrome Tips (140797BC) - 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 140797BC 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 black chrome premium 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.
Black Chrome Tip Care & Maintenance: The premium 4-inch black chrome finish on this system requires specific maintenance to safeguard its deep, mirror-like luster. Using abrasive metal cleaner or standard stainless steel polishes (such as Borla 21499) is NOT recommended with these specialized black chrome tips. To avoid damaging the finish, simply clean the tips using hot water and a soft microfiber cloth.
