Description
This Flowmaster Outlaw Cat-back exhaust system is perfect for the person looking for maximum sound levels both inside and outside the vehicle and are not afraid of getting peoples attention. This emissions-legal system is for the 2019 (new body style) to 2022 GM Silverado/Sierra 1500 trucks with 5.3L engine and features a stainless steel Super 10 Series muffler, all mandrel-bent 3.00-inch stainless steel tubing and uses the factory hanger locations for an easy installation. The large dual 3.00-inch stainless tailpipes ensure maximum power and a deep powerful sound. This bolt-on system comes with your choice of tailpipe exits, either dual out the rear, or dual out the sides behind the rear wheels which prevents blowing exhaust on your boat or trailer when towing. The system is finished off with a pair of large 4.00-inch double wall black ceramic coated stainless tips for a custom look. Designed for a perfect-fit, the system includes installation instructions and all the necessary hardware for an easy at home installation. Maximum dyno gains of 10 hp and 13 lb. Ft. at the rear wheels. Notes: Fits Crew Cab and Double Cab models with factory single tailpipe only.
