Borla S-Type Cat-Back Exhaust System with Single Bright Chrome Tip (140794) - 2019-2026 Silverado / Sierra 1500 4.3L & 5.3L
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 2026 Chevrolet Silverado 1500 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 both the 4.3L V6 and 5.3L V8 engines a bold, crisp 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 140794 targets key factory flow restrictions by incorporating an upgraded high-efficiency performance layout featuring a large 3-inch inlet diameter that maintains optimal velocity. This performance architecture utilizes ultra-smooth mandrel bends and patented multi-core internal geometry that maximizes exhaust velocity and optimizes 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 clean single passenger-side exit layout finished with a massive 4-inch single round, rolled edge angle-cut bright chrome premium mirror-polished T-304 stainless steel tip. Precision CNC-manufactured for an accurate line-to-line bolt-on fitment, this system utilizes all factory mounting positions and is backed by Borla’s legendary lifetime Million-Mile Warranty.
