The Gibson Dual Extreme cat-back exhaust for 2003–2006 Toyota Tundra Limited 4.7L is a bolt-on stainless system positioned behind the rear tires at an aggressive angle to deliver bold street presence and a powerful exhaust tone. Dyno-tested to return roughly 15–20 horsepower gains, it pairs mandrel-bent tubing with a baffled Superflow muffler and polished slash-cut clamp-on tips, includes factory-style hangers and hardware, and installs without welding under a Lifetime Limited Warranty.
