Maximum Sound Levels. The Flowmaster Outlaw Cat-Back Exhaust is designed to deliver the maximum aggressive sound level inside and outside the cab. It’s ideal for enthusiasts who want the most aggressive-sounding truck while enjoying the renowned performance benefits of a Flowmaster exhaust.

High-Performance Exhaust. The Outlaw utilizes Flowmaster’s patented Delta Flow technology which helps improve scavenging. Combining the Delta Flow with the smoother exhaust flow of the mandrel-bent tubing results in a significant increase in the Silverado’s performance.

High-Quality Construction. The Outlaw Cat-Back Exhaust is made from high-grade stainless steel and is built to last. Additionally, the black ceramic coated tips add a rugged finished look to your truck.

Straight Forward Installation. The Outlaw Cat-Back Exhaust is designed for an easy fit to the specific application. Additionally, it comes with the necessary parts for either a split side or dual rear configuration. Flowmaster recommends welding the slip-fit connections for a more secure installation.
