Product Description

The Borla 140545 S-Type Cat-Back Exhaust System is a high-quality performance exhaust engineered specifically for 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 models - plus 2019 Silverado/Sierra 1500 LD ONLY - powered by the 5.3L V8 engine. Designed to replace the factory exhaust from the catalytic converter back, this Cat-Back system increases exhaust gas velocity and reduces backpressure, helping improve throttle response and overall engine efficiency. Borla's patented straight-through and multi-core technology delivers the signature "Sound of Power" with an aggressive, performance-oriented tone that's louder than stock without excessive drone.

Constructed from premium T-304 stainless steel with precision mandrel-bent tubing, the 140545 exhaust offers superior corrosion resistance and long-term durability. Its truck-specific split side exit and polished 4" round rolled angle-cut tip add a classic, high-quality finish to your Silverado or Sierra's rear profile. This direct bolt-on Cat-Back exhaust includes all necessary hardware for a straightforward installation and is backed by Borla's Million-Mile Warranty, making it an excellent upgrade for truck owners seeking enhanced sound, performance, and reliability.
