Product Details

The Flowmaster 717987 Flow FX Cat-Back Exhaust System delivers enhanced performance and an aggressive exhaust note for your truck. This complete cat-back system features Flowmaster's straight-through FlowFX muffler technology, engineered to maximize exhaust flow while producing a bold yet refined sound.

Performance Gains:

  • Maximum gains of 10 horsepower and 10 lb-ft of torque at the rear wheels over stock exhaust
  • 3.50-inch inlet transitioning to dual 3.00-inch mandrel-bent tubing for optimized exhaust flow
  • Straight-through muffler design reduces backpressure and improves throttle response

Quality Construction:

  • 16-gauge 409 stainless steel tubing for superior durability and corrosion resistance
  • Mandrel-bent tubing maintains consistent pipe diameter for maximum flow efficiency
  • 4.00-inch black stainless steel exhaust tips add a custom, aggressive appearance

Easy Installation:

  • Complete bolt-on cat-back system includes all necessary hardware
  • Factory-styled hangers designed to mount in stock locations
  • No cutting or welding required for installation

The FlowFX muffler produces an aggressive to moderate exhaust tone that's perfect for enthusiasts who want improved performance and sound without excessive drone during highway cruising. This system combines Flowmaster's proven performance technology with quality materials for long-lasting durability.
