Product Description

The Borla 140794 S-Type Cat-Back Exhaust System is engineered to upgrade both performance and sound for 2019-2025 Chevrolet Silverado 1500 or GMC Sierra 1500 trucks equipped with either the 4.3L V6 or 5.3L V8 engine and automatic transmission. Built from premium T-304 stainless steel with precision mandrel bends, this exhaust system improves exhaust flow over stock while delivering Borla's signature aggressive performance sound - louder and deeper than the factory system but with minimal cabin drone.

Featuring a single polished 4" rolled angle-cut tip and a truck side exit, the 140794 adds both visual flair and improved exhaust character. This system is designed for vehicles with a factory side exit exhaust, and some wheelbase/bed configurations (such as crew cab with a standard bed) may require Adapter 60708 for proper installation. The bolt-on direct fit design uses supplied hardware and factory mounting points, making installation straightforward. Backed by Borla's Million-Mile Warranty, the 140794 is built to offer long-lasting enhanced sound, performance, and durability.
