Description
Race-Inspired Aggressive Sound. The Flowmaster Outlaw Cat-Back Exhaust is designed to deliver aggressive sound levels both internally and externally. This lets enthusiasts experience Flowmaster’s renowned sound while also enjoying their exhaust’s performance-boosting characteristics. Due to the sound levels emitted, this system is not intended for street driving. As a bonus, the exits can be configured as either split side or dual rear for flexible customization.
High-Performance Exhaust. Flowmaster’s patented Delta Flow™ technology and the precision-machined mandrel-bent tubing dramatically improve scavenging and exhaust flow to improve your truck’s performance. Each system is dyno-tuned for the best performance.
High-Quality Materials and Construction. Like other Flowmaster products, the Outlaw is made from high-grade stainless steel and built to last. Additionally, the black ceramic coated tips add a rugged finished look to your truck.
Direct Fit Replacement Upgrade. The Outlaw is precisely designed to fit your application and requires no additional fabrication. The installation utilizes the factory mounting point to simplify the process. And while not required, Flowmaster recommends welding the slip-fit connections for a more secure installation.
Application. The Flowmaster Outlaw Cat-Back Exhaust with split side or rear exit is designed to fit Fits 2014 to 2017 Chevrolet Silverado 1500 5.3L models with either Double or Crew Cab. It’s not compatible with 2WD Crew Cab models with the 2-piece driveshaft.
