Description
The Flowmaster Outlaw Cat-Back Exhaust System is designed for 2019–2026 GM Silverado and Sierra 1500 trucks with the 5.3L engine. Built for drivers who want maximum attention with aggressive sound, this bolt-on exhaust system features a stainless steel Super 10™ Series muffler and all mandrel-bent 3.00-inch stainless steel tubing.
Dual 3.00-inch stainless steel tailpipes exit either out the rear or out the sides behind the rear wheels, ideal for towing applications to prevent exhaust from blowing onto boats or trailers. Finished with large 4.00-inch double-wall black ceramic-coated stainless steel tips, this system delivers a show-quality custom look with deep, powerful sound inside and outside the cab.
Installation is straightforward using all factory hanger locations. The system comes complete with all necessary hardware and instructions, making at-home installation simple. Maximum dyno gains of 10 hp and 13 lb-ft at the rear wheels ensure performance is enhanced alongside its aggressive tone.
