Borla S-Type Cat-Back Exhaust System w/ Black Chrome Tips - 2020-2026 Silverado/Sierra 2500 & 3500 6.6L V8 (140833BC)
Unleash the acoustic power and performance potential of your heavy-duty truck with the Borla S-Type Cat-Back Exhaust System for the 2020-2026 Chevrolet Silverado and GMC Sierra 2500/3500 models equipped with the 6.6L V8 gasoline engine. This premium 3.5-inch diameter system features Borla's classic S-Type sound level, adding a throaty, aggressive growl under acceleration that perfectly complements your truck's heavy-duty character. Engineered with patented straight-through and multi-core muffler technology, this system maximizes exhaust velocity to improve throttle response and horsepower when hauling or trailering, all while guaranteeing a completely comfortable, drone-free cabin environment on long highway hauls.
Built to handle the severe workloads, high heat, and rugged environments typical of heavy-duty trucks, this exhaust assembly is manufactured entirely from top-tier T-304 austenitic stainless steel to deliver ultimate defense against structural rust and corrosion. Ultra-smooth, CNC mandrel-bent tubing ensures unrestricted airflow, eliminating high-friction power bottlenecks. The system routes flawlessly to a clean truck side exit behind the passenger rear tire and terminates in an aggressive 5-inch round black chrome on T-304 stainless steel tip for a commanding, stealthy custom look. This direct bolt-on setup fits standard-bed models perfectly out of the box, is proudly made in the USA, and is backed by Borla's iconic lifetime Million-Mile Warranty.
