Sound Level Ideal for Street Driving. The Flowmaster Force II Cat-Back Exhaust is great for street driving. Flowmaster’s Delta Flow technology lets them calibrate the exhaust to deliver a mild to stock interior sound level while delivering a richer tone and moderate sound level outside. This lets you enjoy all the performance benefits of a Flowmaster exhaust without disturbing the neighbors.

Significant Performance Improvements. Flowmaster’s patented Delta Flow technology is designed to improve scavenging. In combination with the mandrel-bent tubing’s smoother exhaust flow, it improves the Silverado’s throttle response, power, and mileage.

304S Stainless Steel Construction. The Force II Cat-Back Exhaust is made from high-grade stainless steel for durability and longevity. Additionally, the polished stainless steel tips give the exhaust a good-looking finish.

Designed for Easy Fit. The Force II Cat-Back Exhaust is specially designed for its application and uses factory mounting points to further simplify the installation. It can be configured with either dual side or dual rear exits. Flowmaster recommends welding the slip-fit connections for a more secure installation.

Application. The Flowmaster Force II Cat-Back Exhaust with split side or rear exit is designed to fit 2014 to 2018 Chevrolet Silverado 1500 5.3L models equipped with Double or Crew Cab. It’s not compatible with 2WD Crew Cab models with 2-piece driveshaft.
