Flowmaster 04-07 5.4L F-150 American Thunder Dual Exit CatBack

  • Flowmaster American Thunder Dual Exit Cat-Back Exhaust System (Optional Dual Rear or Side Exit, Behind Rear Axle)
  • Dual 2.50-inch, mandrel bent aluminized tail-pipes
  • Two 3-inch, angle cut stainless steel tips
  • Works With All 2 and 4 Wheel Drive Trucks
  • Super 40 Series Mufflers



The D.O.R. systems are designed for the person who wants that custom look of a dual exhaust on a late model vehicle that came with a factory single exhaust. These systems feature mandrel bent 16 gauge aluminized steel tubing, either weld-on or flanged inlet pipe/pipes, specially tuned muffler, clamps, hangers and stainless steel exhaust tips for that aggressive look and sound of a dual exhaust system.
