Gibson 17-22 Toyota 4Runner Base 4.0L 2.5in Cat-Back Single Exhaust - Stainless

This Gibson cat-back exhaust system is made specifically for your 2004-2024 Toyota 4Runner with the 4.0L engine. It's designed to replace your factory exhaust from the catalytic converter back, exiting behind the rear tire with a polished stainless steel slash-cut tip. If you're looking to get more out of your 4Runner when climbing hills, towing, or just need that extra bit of power for passing, this system can help.

Gibson's Superflow muffler uses a baffled and chambered design, meaning it doesn't rely on internal packing material to quiet things down. This approach helps it flow better, and dyno tests show it makes its biggest gains in torque and horsepower between 1800 and 3000 RPM, which is exactly where you need it for low-end grunt. You can expect an average increase of 10-15 horsepower and 15-20 lb-ft of torque. Despite being a performance exhaust, Gibson has worked to minimize interior drone, so you get an aggressive sound outside without excessive noise inside the cab. The tubing is made from mandrel-bent stainless steel, ensuring consistent diameter and smooth flow throughout, and the whole system is built to last with a Lifetime Limited Warranty.

Installation is designed to be straightforward. It bolts directly onto your existing factory hangers, and no welding is required, making it a hassle-free upgrade. All the necessary hardware and factory-style hangers are included to get you up and running.
