Flowmaster introduces their new Outlaw Extreme Cat-back system for the 2009-2013 Chevrolet Silverado & GMC Sierra 1500 trucks with the 5.3L engine. These kits deliver the ultimate sound in aggressive exhaust systems by using a race-proven 3.00-inch stainless steel Outlaw muffler with a 3.00-inch dump style turn down exit with no tailpipes. As an Outlaw extreme system, this will deliver a very aggressive sound and tone both outside and inside the truck. The stainless steel system is covered by our Lifetime Limited Warranty and includes all of the necessary parts and hardware for an easy installation you can do at home. This system fits both 2/4 wheel drive Extended Cab and Crew Cab models only with 143.5 and 157.5-inch wheelbases.
