Our new Flowmaster® FlowFX® cat-back exhaust system for the 2009-2013 GM Silverado/Sierra with 4.8L and 5.3L engines is manufactured using 409S stainless steel for years of trouble free service. System features include a 3.00-inch inlet pipe leading into a FlowFX "straight-through" performance muffler for great sound and maximum performance. The single 3.00-inch mandrel-bent tailpipe exits out the side behind the passenger side rear tire and is finished off with large 4.50 inch diameter black ceramic coated 304S stainless steel tip, giving your Silverado or 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 without any cutting or welding for an easy installation that you can do at home. Includes installation instructions and all necessary hardware. Note: Fits both 2/4 Wheel Drive models with 143.5 and 157.5-inch Wheelbases.

  • Large 4.50-inch Black Ceramic Coated Stainless Steel Tip

  • FlowFX "Straight-through" Performance Muffler
  • Mandrel-bent Stainless Steel Tubing
