Gibson 2004-2023 Toyota 4Runner 4.0L 2.5in Cat-Back Single Exhaust - Stainless

Gibson 618815 cat-back single exhaust system upgrades 2004-2023 Toyota 4Runner models with a 4.0L V6 engine. Single side exit behind the rear tire boosts acceleration, hill climbing, towing and passing power through dyno-proven low-end torque and horsepower from 1800-3000 RPM. Average gains of 10-15 horsepower and 15-20 lb-ft torque make it ideal for daily driving and off-road demands.

Key Features

  • Performance Gains: Dyno tests confirm 10-15 HP and 15-20 lb-ft torque increases focused at low RPM for real-world power in acceleration, towing and passing.
  • Single Side Exit: Positions outlet behind rear tire for balanced flow and aggressive sound without drone inside the cab.
  • Quiet Cabin: Engineered muffler design keeps interior noise lower than other performance exhaust options while delivering deep tone outside.
  • Bolt-On Installation: Direct fit using factory mounting points with no welding or cutting required for professional results.
  • Stainless Steel Construction: 409-grade tubing and polished tips resist corrosion for long-lasting durability and mirror finish.

Product Notes

  • Designed for 4.0L V6 engines across multiple 4Runner trims from 2004-2023.
  • Moderate exterior sound level suits street and trail use.
  • Ships as complete assembly ready for installation.

Installation Notes

  • Professional installation recommended.
  • Bolt-on design reuses OEM hangers and clamps for 1-2 hour install.
  • Compatible with factory cat and headers, no modifications needed.
