Product Description

The Borla 140915 ATAK® Cat-Back Exhaust System is designed to transform the exhaust sound and performance of your 2022-2023 Chevrolet Silverado 1500 ZR2 or GMC Sierra 1500 AT4X equipped with the 6.2L V8 engine, four-wheel drive, and automatic transmission. Featuring Borla's aggressive ATAK® muffler and patented Polyphonic Harmonizer Technology, this exhaust produces a rich, full-bodied tone throughout the RPM range while minimizing drone on the road. Built from premium T-304 stainless steel with smooth mandrel bends, it enhances exhaust flow and throttle response with lasting durability.

Installation is simple with the direct bolt-on design that replaces your stock exhaust without cutting. The turn-down tailpipes with a single split rear exit provide an aggressive visual upgrade that matches the truck's rugged character. For a quieter sound resembling Borla's S-Type profile, the Polyphonic Harmonizer can be swapped with muffler 60679 (sold separately). Backed by Borla's Million-Mile Warranty, the 140915 ATAK® exhaust system is a premium upgrade for enthusiasts seeking maximum exhaust presence and performance on the ZR2 and AT4X platforms.
