The Gibson cat-back single exhaust for 2003–2006 Toyota Tundra SR5 (4.7L) is designed to improve acceleration and hill-climbing power while maintaining a quieter cabin. Dyno-tested for low-end gains, the stainless single-exit system uses mandrel-bent tubing and a baffled Superflow muffler to deliver stronger torque at 1800–3000 RPM. It includes a polished slash-cut tip, factory-style hangers and hardware for easy bolt-on installation and is backed by a lifetime limited warranty.
