Gibson 03-06 Toyota Tundra SR5 4.7L 2.5in Cat-Back Single Exhaust - Aluminized

If you're looking to get more out of your 2003-2006 Toyota Tundra SR5, especially when it comes to hauling or climbing hills, a cat-back exhaust system like this one from Gibson can make a notable difference. This system is designed to bolt directly onto your Tundra's existing exhaust, exiting behind the rear tire with a polished stainless steel slash-cut tip. It's built to improve acceleration and low-end torque, giving you that extra push when you need it most.

Gibson uses aluminized, mandrel-bent tubing for this system, which helps maintain consistent exhaust flow. The included baffled and chambered muffler is engineered to provide a more aggressive sound outside the vehicle while minimizing interior drone, so your cabin stays comfortable. Installation is straightforward thanks to the bolt-on design and factory-style hangers, meaning no welding is required. You can expect an average gain of 10-15 horsepower and 15-20 lb-ft of torque, particularly in the 1800 to 3000 RPM range.
