About the manufacturer

Introducing our new Flow FX® Cat-back exhaust system for the 2019-2026 GM Silverado/Sierra 1500 with the 5.3L engine. The performance exhaust system fits both 2 and 4-Wheel drive models with 148 or 157-inch wheelbases and is manufactured from 409S stainless steel for years of trouble-free service. Features include a 3.00-inch inlet pipe leading into a Flow FX "straight-through" muffler for great sound and maximum performance. Maximum dyno gains of 10 hp and 12 lb.ft of torque at the rear wheels. The 3.00-inch mandrel-bent tailpipe exits out behind the rear passenger side tire and is finished off with large 4.50-inch diameter black ceramic coated 304S stainless steel tip, giving your Silverado/Sierra that custom look that goes hand in hand with the deep performance sound of the Flow FX muffler. The system uses all the factory hanger locations and connections for an easy installation that you can do at home. Includes detailed instructions and all necessary hardware.
