Introducing the new FlowFX Cat-back exhaust system for 2014-18 GM Silverado/Sierra 4.3L and 5.3L engines. This performance exhaust system fits both 2 and 4-Wheel drive models with 143.5 and 153-inch wheelbases and is manufactured from 409S stainless steel for years of trouble-free service. Features include 3.00-inch inlet pipe leading into a FlowFX "straight-through" muffler for great sound and maximum performance. The single 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 FlowFX muffler. The system uses all the factory hanger locations and connections for an easy installation that you can do at home. Includes installation instructions and all necessary hardware.Exhaust Type: Cat-BackExit Position: Single SideInlet Inside Diameter: 3.000 in.Material: Stainless SteelTail Pipe Diameter: 3.000 in.Tip Diameter: 4.500 in.Tubing Diameter: 3.000 in.WARNING CA Proposition 65: YesWARNING CA Proposition 65 Message: WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov
