Borla S-Type Cat-Back Exhaust System for 2019-2025 Silverado/Sierra 1500 (5.3L) 147.4 WB

Fits select 2019-2025 Chevrolet Silverado 1500 and GMC Sierra 1500 (5.3L) models with 147.4-inch wheelbase. Designed exclusively for vehicles with factory single side exit exhaust.

The Borla S-Type Cat-Back exhaust system (MPN 140794) is engineered to improve exhaust velocity and engine efficiency for the 5.3L V8. Constructed from premium T-304 austenitic stainless steel, this system features 3-inch mandrel-bent tubing and Borla's patented straight-through, multi-core technology. This design provides a significant increase in flow over the restrictive factory setup while delivering the aggressive S-Type sound profile without interior cabin drone.

This system installs to factory mounting points and features a side exit behind the passenger rear wheel. For Crew Cab Standard Bed (6' 7") models with a 157-inch wheelbase, adapter 60708 is required (sold separately).
