Cat BAck Exhaust Kit 14- 19 GM P/U 1500 5.3L

The Flowmaster Cat-Back Exhaust Kit for 2014–2019 GM P/U 1500 5.3L delivers aggressive performance and signature Flowmaster sound through a complete stainless steel system. This cat-back exhaust kit is engineered for the GM GenV LT-Series engine platform found in full-size Chevrolet and GMC trucks, replacing the factory restrictive exhaust components with a high-flow design that improves both aesthetics and engine efficiency.

The 3-inch diameter tubing provides optimal scavenging characteristics for the 5.3L powerplant while maintaining structural integrity and longevity. Stainless steel construction resists corrosion from road salt, moisture, and seasonal weather exposure—critical for truck owners who rely on durability across varied climates. The single underbody exit design routes exhaust away from the vehicle's rear, delivering the Outlaw Extreme tone profile Flowmaster is known for. Black powder-coat finish complements modern truck styling while protecting against thermal degradation and road debris.

This kit suits truck owners seeking improved horsepower and torque response without complex tuning or engine modifications. Whether used for weekend hauling, towing, or daily driving, the cat-back configuration preserves the factory catalytic converter and emissions compliance while freeing up backpressure. Installation typically requires basic hand tools and modest mechanical familiarity, with factory connection points making fitment straightforward on 2014–2019 Silverado 1500 and Sierra 1500 models. The complete system arrives as a coordinated assembly, eliminating the need to source individual components and ensuring proper alignment and finish consistency.
