Gibson 04-22 Toyota 4Runner LImited 4.0L 2.5in Cat-Back Single Exhaust - Aluminized

Gibson is known for making well-built exhaust systems that improve performance. This cat-back system is specifically made for your 2004-2024 Toyota 4Runner Limited with the 4.0L engine, and it's designed to give you a noticeable boost in power where you'll use it most. If you're looking to get more out of your 4Runner when climbing hills, towing, or just need that extra bit of passing power, this system is a solid choice. It exits behind the rear tire for a clean look.

This system uses aluminized, mandrel-bent tubing for smooth exhaust flow, which helps the engine breathe better. The Superflow muffler is baffled and chambered, meaning it's built to reduce interior noise and drone while still giving you an aggressive sound outside the vehicle. Dyno tests show this system adds an average of 10-15 horsepower and 15-20 lb-ft of torque, especially in the low-end RPM range between 1800 and 3000 RPM. It also includes polished stainless steel slash-cut tips for a finished look.

Installation is straightforward thanks to the bolt-on design, which uses factory-style hangers and includes all the necessary hardware. No welding is required, making it a hassle-free upgrade. Gibson backs this exhaust system with a Lifetime Limited Warranty, so you can be confident in its durability.
