Product Details

The Flowmaster Flow FX Cat-Back Exhaust System delivers enhanced performance and a custom appearance for your truck. This complete exhaust system features mandrel-bent stainless steel tubing and a straight-through performance muffler designed to maximize exhaust flow while producing a deep, moderate tone.

Performance Gains:

  • Maximum increases of up to 14 horsepower and 13 lb-ft of torque over stock exhaust at the rear wheels
  • FlowFX straight-through performance muffler improves exhaust flow and reduces backpressure
  • 3.00-inch to dual 2.50-inch mandrel bent tubing maximizes flow efficiency

Quality Construction:

  • 16-gauge 409 stainless steel tubing for superior durability and corrosion resistance
  • Dual 4.00-inch black ceramic coated exhaust tips for an aggressive custom look
  • Moderate, deep exhaust tone that's not overly loud

Installation:

  • Complete cat-back system includes all necessary hardware
  • Factory-styled hangers mount in stock locations for direct fit
  • Designed for straightforward bolt-on installation

This Flowmaster exhaust system combines performance, sound, and style to transform your truck's exhaust while maintaining quality and durability.
