Product Description

The Borla 140793BC Touring Cat-Back Exhaust System is a direct bolt-on performance upgrade purpose-built for 2019-2025 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks equipped with the 4.3L V6 or 5.3L V8 and factory single side exit. Constructed from premium T-304 austenitic stainless steel with precision CNC mandrel bends, this system improves exhaust flow over the factory setup for real gains in horsepower, torque, and fuel efficiency - all while maintaining the refined character expected of a daily-driven truck.

The Touring sound tuning delivers a subtle, confident exhaust note that's noticeably better than stock without any highway drone - ideal for drivers who want improved performance and a cleaner sound without going full aggressive. A single black chrome 4 in. round tip exits cleanly through the factory passenger-side opening, giving the truck a premium blacked-out finish. Owners of Crew Cab trucks with Standard Bed at the 157 in. wheelbase will need to add the optional Borla Adapter (Part# 60708), sold separately.
