Product Description

The Borla 140780 Touring Cat-Back Exhaust System is engineered for 2019-2025 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks equipped with the 5.3L V8 and automatic transmission. Developed with premium T-304 stainless steel and precision mandrel bends, this exhaust system enhances performance and throttle response while producing a refined touring sound with minimal drone, ideal for daily driving. The patented straight-through, multi-core design balances increased exhaust flow with a comfortable sound level that's louder than stock but still well-suited for everyday use.

Featuring dual bright chrome square rolled angle-cut tips, the 140780 adds a polished look to your truck's rear profile. This system fits factory split rear exit configurations and includes Trail Boss models within the fitment range. Some wheelbase and bed combinations, such as crew cab with standard bed 157" wheelbase vehicles, require Adapter 60708 for correct fitment. Installation requires removal of the factory valance tips and uses standard hand tools and the included hardware kit. Backed by Borla's Million-Mile Warranty, the 140780 delivers lasting performance, improved exhaust flow, and a smooth, mild performance exhaust note.
