Product Details

The Flowmaster 718111 FlowFX Cat-Back Exhaust System delivers aggressive sound and performance gains for your truck. This complete exhaust system features Flowmaster's "straight-through" FlowFX muffler design that improves exhaust flow while producing a deep, aggressive to moderate performance tone.

Performance Features:

  • Maximum increases of up to 9 horsepower and 10 lb-ft of torque over stock exhaust at the rear wheels
  • 3.50-inch to dual 3.00-inch mandrel-bent tubing maximizes exhaust flow and scavenging
  • FlowFX straight-through muffler technology reduces backpressure for improved performance
  • Constructed from 16-gauge 409 stainless steel for superior durability and corrosion resistance

Installation and Styling:

  • 4.50-inch black ceramic coated exhaust tips add a custom, aggressive appearance
  • Includes complete hardware and factory-styled hangers in stock locations for bolt-on installation
  • Mandrel-bent tubing maintains consistent diameter throughout for optimal flow

This cat-back system is designed as a direct replacement for your factory exhaust, offering improved performance, enhanced sound, and distinctive styling without compromising daily drivability.
