Overview:

Flowmaster introduces our Outlaw Extreme stainless steel cat-back exhaust system for the 2003-2024 Toyota 4Runner with the 4.0L 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 allows for maximum exhaust flow and better 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 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:

  • Flow FX 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 18 HP and 9 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

    My dogs love them
    Size: Large, Style: Peanut Butter
    One of the few toys my pit bulls can't break. They absolutely love these toys and play chase with them. Usually, they can break toys in less than 5 minutes, but not these.

    Good quality, not a bad price
    Size: Large, Style: Peanut Butter
    Good value. It was cheaper to buy the pack of three instead of buying three separate. I wanted to try different shapes for the dogs. Honestly, they aren’t impressed, but it’s not due to a lack of quality of the product. It’s because they would rather shred Kleenex, eat dog poop, and steal chicken eggs.

    My dogs love love love these
    Size: Large, Style: Peanut Butter
    Repeat buyer here. I have Blue Heelers and Aussies so I have purchased many of the jumbo balls and we have loved them. I decided to gift this set to a friend. The pups ages range from 4 months-11 years and they adore these toys, even sleep with them! If you want to train your dogs to play with toys instead of your belongings, you can't go wrong with this peanut butter trio!
