Product Details

The Flowmaster Flow FX Cat-Back Exhaust System delivers a noticeable performance upgrade for truck owners seeking improved horsepower, torque, and a distinctive sound. This complete bolt-on system features Flowmaster's FlowFX "straight through" muffler design that reduces backpressure while producing a deep, moderate performance tone that's aggressive without being overwhelming.

Performance Gains:

  • Increases up to 7 horsepower and 12 lb-ft of torque over stock exhaust at the rear wheels
  • 3.50-inch mandrel bent tubing maximizes exhaust flow throughout the system
  • FlowFX straight-through muffler technology improves exhaust scavenging and reduces restriction

Quality Construction:

  • 16-gauge 409 stainless steel tubing for long-lasting durability and corrosion resistance
  • Mandrel bent pipes maintain consistent diameter throughout bends for optimal flow
  • 5.00-inch black ceramic coated exhaust tip adds a custom, aggressive appearance

Easy Installation:

  • Complete cat-back system includes all necessary hardware for installation
  • Factory-styled hangers designed to mount in stock locations
  • Bolt-on design allows for straightforward installation with basic tools

Backed by Flowmaster's Lifetime Limited Warranty, this exhaust system is engineered to provide years of reliable performance and distinctive sound. The moderate tone makes it ideal for daily driving while still delivering an enthusiast-grade exhaust note under acceleration.
