The Gibson Cat‑Back Dual Sport Exhaust for 2004–2022 Toyota 4Runner (4.0L) is a stainless dual system that exits behind the rear tire to protect tow trailers and give a distinct look. Dyno testing supports average gains of 10–15 hp and 15–20 lb‑ft, while a baffled Superflow muffler delivers a deep tone without intrusive cabin noise. The kit includes polished clamp‑on tips, mandrel‑bent tubing and hardware for an easy bolt‑on installation.
