Introducing our new FlowFX® Cat-back exhaust system for the 2019-2020 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 in. wheelbases and is manufactured from 409S stainless steel for years of trouble-free service. Features include a 3.00 in. inlet pipe leading into a FlowFX straight-through muffler for great sound and maximum performance. The 3.00 in. mandrel-bent tailpipe exits out behind the rear passenger side tire and is finished off with large 4.50 in. 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 FlowFX 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.
