Overview:

Flowmaster introduces our Flow FX Extreme stainless steel cat-back exhaust system for the 2003-2024 Toyota 4Runner with the 4.0-liter engine. This system uses a Flow FX series muffler for an aggressive sound level and increased performance. 3.00-inch mandrel bent 409 stainless steel tubing allows 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 improve ground clearance and departure angle when you are driving in more extreme off-road situations. This system produced max dyno gains of 4 hp and 5 lb-ft at the rear wheels. 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 an aggressive to moderate sound level and increased performance
  • 409 stainless steel construction delivers extra durability and improved long-term corrosion resistance
  • Max dyno gains of 5 hp and 6 lb-ft of torque at the rear wheels
  • 3.00-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

    Eh...
    Size: 5 in
    I had high hopes for these cause we have other spot brand toys that have last a long time. Unfortunately these just don't hold up to the test! My dogs had them broken in about 5 - 10 mins. They did smell good tho and my dogs went crazy over them before I ever got them out of the bag. Lol.

    Smells too strong
    Size: 5 in
    My dog hates the way this thing smells. She tries to play with it, but the scent is too strong for her nose. I know it's the scent because she usually sniffs it two or three times in between trying to grab it with her mouth. She treats it like an explosive in her mouth and quickly moves away after spitting it out. She used to have a bone that looked similar to this (same material) that was unscented and she gnawed the hell out of it. My sister's pitbull spent the night and chewed that toy into bits, leaving my Yorkie mourning the loss of her once treasured bone. Please make an UNSCENTED version of this toy!!!!

    Bully proof?!
    Size: 5 in
    We have the cutest little pit/lab mix who destroys stuffed toys in about two seconds flat. It’s always a HUNT to find toys he won’t instantly shred. This brand has some of the best! They were in FiveBelow for a while and it was the only brand that stood up to him initially. He finally got through the first only after MONTHS so we bought a few back ups and they’re still going strong months later! They’re also not super heavy so these end up being the toys we play fetch with most often! 100% will be buying more in this line in the future!

    Great Option
    Size: 5 in
    When this chew arrived, it immediately became a favorite. It seems sturdy and is soft enough to be dental friendly.
