Flowmaster introduces our FlowFX Extreme stainless steel cat-back exhaust system for the 2010-2022 Toyota 4Runner with the 4.0-liter engine. This system uses a FlowFX series muffler for an aggressive to moderate 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:

  • FlowFX 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 4 hp and 5 lb-ft 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
  • Dump style exit allows for better ground clearance when in extreme off-road conditions
  • Uses factory hanger locations for easy installation
  • Lifetime Limited Warranty
