The Gibson single-side cat-back exhaust for 2004–2022 Toyota 4Runner Limited 4.0L is an aluminized bolt-on system focused on improved acceleration, hill-climbing and towing. It exits behind the rear tire to reduce in-cab noise while increasing low-end torque and horsepower (typical gains around 10–15 hp and 15–20 lb‑ft). Includes baffled Superflow muffler, polished tip, mandrel-bent tubing and hardware for straightforward installation and a lifetime limited warranty.
