Product Details

The Flowmaster 817981 Outlaw Cat-Back Exhaust System delivers aggressive sound and performance gains for your truck. This complete system features the legendary Super 10 Series performance muffler, engineered to produce a deep, powerful exhaust note while maximizing exhaust flow for improved horsepower and torque.

Key Features:

  • Super 10 Series performance muffler provides aggressive sound and increased performance
  • 3.0-inch mandrel bent tubing constructed from 16-gauge stainless steel for maximum exhaust flow
  • Dual exit configuration with both rear and side exit tailpipes included—choose your preferred style
  • Large 4.0-inch black ceramic coated tips add a distinctive, custom appearance
  • Full stainless steel construction ensures superior durability and corrosion resistance
  • Uses factory hanger locations for straightforward bolt-on installation
  • Designed to clear factory spare tire location
  • Backed by Flowmaster's Lifetime Limited Warranty

This Outlaw system combines Flowmaster's proven performance technology with versatile styling options, allowing you to customize your truck's look while enjoying enhanced exhaust flow and that unmistakable Flowmaster sound.
