The Gibson Cat‑Back Single Exhaust for 2001–2004 Toyota Tacoma S‑Runner (3.4L) is a stainless single‑side system that exits behind the rear tire to improve low‑end torque and acceleration. Dyno testing shows gains focused at 1800–3000 RPM; typical increases are 10–15 hp and 15–20 lb‑ft. The kit includes factory‑style hangers, mandrel‑bent tubing and a baffled muffler for a quieter cabin and bolt‑on installation.
