Product Description   

Unleash the full potential of your truck with the Borla BOR140540 and BOR140570 Cat-Back Exhaust Systems, engineered exclusively for 2014–2018 Chevrolet Silverado 1500 and GMC Sierra 1500 models equipped with the 6.2L V8. Designed as a direct replacement for the factory exhaust behind the catalytic converter, these systems optimize exhaust flow for noticeable gains in throttle response, performance, and efficiency.

Crafted from premium T-304 stainless steel, far superior to common 400-series alternatives, each system features mandrel-bent tubing and precision CNC manufacturing for maximum durability and an exact fit. Drivers can choose between Borla’s signature sound levels—ATAK® for an aggressive, high-performance roar, or Touring for a more refined, subdued tone—with polished or specialty tip finishes to match your truck’s style.

Whether you want to turn heads with a commanding exhaust note or simply elevate your truck’s look and performance, Borla delivers a system that’s built to last and backed by their Million-Mile Warranty.
