Product Description

The Gibson 618815 Stainless Cat-Back Single Exhaust System is a performance-oriented upgrade designed specifically for 2004-2024 Toyota 4Runner models equipped with the 4.0L V6 engine. This direct-fit cat-back replaces the factory exhaust from the catalytic converter back with stainless steel mandrel-bent tubing and a Superflow™ baffled and chambered muffler, improving exhaust flow, increasing low-end torque and horsepower, and providing a deeper, more aggressive exhaust tone with minimal interior drone. The polished stainless steel slash-cut tip offers a premium finish that enhances the rear appearance of the 4Runner.

Installation is straightforward with the included factory-style hangers and all required hardware - no welding is needed, making it an easy bolt-on upgrade. This exhaust system is engineered to maintain proper exhaust routing and clearance while enhancing throttle response, towing performance, and hill-climbing capability. Backed by Gibson's lifetime limited warranty, fitment is confirmed for Toyota 4Runner models from 2004 through 2024 with the 4.0L V6 engine; coverage beyond these model years is unconfirmed at time of listing.
