This Outlaw cat-back exhaust system is for 2009-2013 GM Silverado/Sierra 1500 trucks with the 5.3L engine and is perfect for the person looking for an aggressive sound level, both inside and outside of the truck. This bolt-on emissions-legal system features 3.00-inch mandrel-bent stainless steel tubing flowing into a Super 10 Series muffler, for a deep powerful aggressive sound. The large 3.00-inch mandrel-bent stainless steel tailpipes can be configured with your choice of exit locations, either straight out the back under the bumper for a muscular look, or exiting out behind the rear tires on each side of the truck. The side exit tailpipes are the ideal exit location when towing a boat or RV. The tailpipes are finished off with large 4.00-inch black ceramic coated dual-wall stainless steel tips. The system includes all necessary parts and hardware for an easy installation and is covered by our Lifetime Limited Warranty.
