Flowmaster introduces the new Outlaw Extreme stainless steel cat-back exhaust system for the 2021 Ford F-150 with the 2.7L, 3.5L, or 5.0L engine. This system uses an Outlaw series muffler for a deep powerful sound and increased performance. 3.0-inch mandrel bent 409 stainless steel tubing is used for maximum exhaust flow and durability. The system has a turndown style dump exit right after the muffler to eliminate the over-axle tailpipe. This elimination of the tailpipe helps to improve ground clearance and departure angle when you are driving in more extreme off-road situations. All of the necessary hardware is included and factory mounting locations are used for an easy installation. Backed by Flowmaster's Lifetime Limited Warranty.

Features:

  • Outlaw series performance muffler offers a deep powerful sound and increased performance
  • 409 stainless steel construction delivers extra durability and improved long-term corrosion resistance
  • Max dyno gains of 7 HP and 10 LB.FT torque over stock at the rear wheels
  • Uses factory hanger locations for easy installation
  • 3.0-inch 16-gauge mandrel bent stainless steel tubing helps maintain maximum exhaust flow for better power
  • Includes all necessary hardware for an at home installation
  • Dump style exit allows for better ground clearance when in extreme off-road conditions
  • Lifetime Limited Warranty
