Flowmaster introduces their new Outlaw Extreme Cat-back system for the 2009-13 GM 1500 series trucks with the 5.3L V8 engine. These kits deliver the ultimate sound in aggressive exhaust systems by using a 3.00-inch Outlaw muffler with a single 3.0-inch dump style turn down exit (no tailpipes). As an Outlaw Extreme system this will deliver a very aggressive sound and tone both outside and inside the truck. This system is for the Double Cab and Crew Cab models only. Constructed with 409S Stainless Steel, this kit is covered by Flowmaster’s Lifetime Limited Warranty and includes all of the necessary hardware for an easy installation.
