This Flowmaster FlowFX cat-back exhaust system is designed for 1999-2007* (*Classic Body) GM Silverado/Sierra 1500 trucks with 4.3L, 4.8L & 5.3L engines and features 409 stainless steel construction for added durability and 16-gauge mandrel-bent tubing for free unrestricted flow. The compact, oval straight-through FlowFX performance muffler attaches behind the catalytic converter and delivers a moderate, deep and powerful sound with minimal interior resonance. The mandrel-bent stainless tailpipe tucks up high in the undercarriage protecting it from being crushed when traversing rocky terrain. This system uses the factory hanger locations and is finished off with a 4.50 in. black ceramic-coated 304 stainless steel tip embossed with the Flowmaster name. The kit includes detailed instructions and all hardware necessary for a quick and easy installation you can do at home. Covered by our Lifetime Limited Warranty.

Features:

  • Increases of 6.7 HP and 6.5 FT/LBS over the stock exhaust
  • System produces a nice rumble with minimal internal resonance
  • Large 4.50-inch black ceramic coated stainless steel tip offers an aggressive look
  • Includes complete hardware and factory styled hangers in stock locations for an easy installation
  • FlowFX "straight-through" performance muffler delivers a deep tone and improved exhaust flow
  • Mandrel-bent 16-gauge 409 stainless steel tubing maximizes exhaust flow with excellent corrosion resistance
  • Lifetime Limited Warranty
