Product Description

The Borla 140537 ATAK Cat-Back Exhaust System is a premium performance exhaust upgrade engineered specifically for 2014-2019 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks equipped with the 5.3L V8 engine (including Silverado/Sierra 1500 LD for 2019). Built from high-grade T-304 stainless steel with precision mandrel bends, this exhaust delivers an aggressive sound signature and optimized exhaust flow.

Installation is straightforward with a direct bolt-on design that utilizes factory hangers and mounting points, requiring no cutting of OEM components. A truck single split rear exit and dual polished 4" round rolled angle-cut tips provide a bold, finished appearance and improved exhaust gas velocity. The straight-through multi-core muffler enhances flow while balancing performance and tone, making the 140537 ideal for truck owners seeking an aggressive upgrade in both sound and exhaust performance.
