Borla ATAK Cat-Back Exhaust System with 4-Inch Black Chrome Tips (140720BC) - 2014-2018 Silverado 1500 & 2014-2019 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 and 2014 to 2019 GMC Sierra 1500 models, this premium full-length exhaust upgrade introduces Borla's legendary acoustic profile: the ultra-aggressive ATAK sound level. Formulated explicitly for driving enthusiasts and performance purists who crave an intense, race-inspired exhaust note under acceleration, this system is calibrated to give the high-output 5.3L EcoTec3 V8 engine a bold, crisp, and high-impact growl. 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 140720BC targets key factory flow restrictions by incorporating an upgraded high-efficiency performance layout featuring a 2.75-inch inlet piping architecture that transitions into dual 2.25-inch mandrel-bent tailpipes out of the muffler. This specialized configuration optimizes scavenging and maximizes exhaust velocity 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 truck split side exit configuration finished with single 4-inch round, rolled edge angle-cut stealth black chrome premium coated T-304 stainless steel tips on each tailpipe that exit cleanly behind the rear tires. 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.
Cab & Bed Configuration Notes: This performance cat-back system is precision-tailored specifically to fit Regular Cab 2-door models equipped with a Standard Bed (6-foot 7-inch bed length) built on a 119-inch wheelbase configuration. It is not designed to clear extended cab, crew cab, or long bed variants.
Chassis & Drivetrain Compatibility: Engineered to mount flawlessly to the 5.3L V8 truck platform running an automatic transmission. This kit provides complete structural clearance for both 2-Wheel Drive (2WD) and 4-Wheel Drive (4WD) drivetrain options.
