Borla S-Type True Dual Cat-Back Exhaust System with Quad Square Bright Chrome Tips (140785) - 2019-2023 Silverado & Sierra 1500 6.2L V8
Wake up the high-performance spirit of your truck with the high-impact Borla S-Type Cat-Back Exhaust System. Custom-engineered for 2019 to 2023 Chevrolet Silverado and GMC Sierra 1500 models, this premium full-length exhaust upgrade introduces Borla's legendary acoustic profile: the classic S-Type sound level. Formulated explicitly for driving enthusiasts and performance purists who crave an aggressive, sport-tuned exhaust note under acceleration, this system is calibrated to give the high-output 6.2L V8 engine a bold, crisp, and high-impact growl. This configuration delivers a commanding exterior acoustic presence while relying on advanced straight-through internals backed by Borla's official No-Drone Guarantee to keep the cabin completely comfortable and drone-free during highway cruising, daily driving, or heavy towing.
The internal engineering of the Borla 140785 targets key factory flow restrictions by incorporating a unique, industry-exclusive True Dual high-efficiency performance layout featuring dual 2.5-inch diameter inlets that transition smoothly into dual 2.75-inch mandrel-bent tailpipes. This premium architecture incorporates a specialized performance muffler with an integrated internal X-Pipe, maximizing exhaust synchronization, accelerating flow velocity, and optimizing scavenging to unlock hidden horsepower, sharper throttle response, and enhanced fuel economy across the entire powerband. Built completely from premium-grade, aircraft-quality T-304 austenitic stainless steel, this highly durable cat-back assembly defends permanently against structural degradation, intense under-car heat cycling, and severe corrosion. The spent exhaust gases exit through a sleek dual split rear exit layout finished with distinctive quad 3.5-inch by 3.28-inch dual square, rolled edge angle-cut bright chrome premium mirror-polished T-304 stainless steel tips on each tailpipe. Precision CNC-manufactured for an accurate line-to-line bolt-on fitment, this system utilizes factory mounting positions and is backed by Borla’s legendary lifetime Million-Mile Warranty.
True Dual Design & Installation Requirements: This ultra-high performance system features a True Dual design that maintains isolated cylinder bank pathing for ultimate power gains. To install this custom architecture, the installation REQUIRES cutting the Original Equipment (O.E.) factory Y-Pipe system.
Bumper & Valance Tip Integration: This system is engineered specifically for trucks equipped with factory integrated bumper exhaust outlets, but it REQUIRES the removal of the original factory valance tips. The premium quad square polished tips replace the restrictive stock inserts entirely, filling out the bumper cutouts for a much more aggressive and high-end customized look.
Cab, Bed & Wheelbase Configuration Notes: This premium performance exhaust system is precision-tailored out of the box to accommodate specific 147.4-inch wheelbase arrangements on the modern GM 1500 platform:
- Extended Cab / Double Cab models paired with a 6-foot 7-inch Standard Bed
- Crew Cab models paired with a 5-foot 9-inch Short Bed
