The Flowmaster American Thunder cat-back exhaust system is designed for the 2000-2006 Toyota Tundra trucks equipped with the 4.7L engine. This performance exhaust features 16-gauge mandrel-bent aluminized steel tubing that flows into a specially designed resonator and a Super 50 Series muffler, delivering a deep, aggressive exterior sound with a moderate interior tone. The system is emissions-legal and bolt-on, with dual options for tailpipe exits—either behind the rear wheels for towing or straight out the back for a muscular appearance. It includes a heat shield, stainless steel clamps, and large polished stainless steel tips, providing durability and a polished look. All necessary hardware for easy installation is included, making it suitable for DIY installation.
This exhaust system fits both 2WD and 4WD models of the 2000-2006 Toyota Tundra with all wheelbases. It is designed as a direct bolt-on upgrade to enhance sound and performance, ideal for street driving and daily use. The system’s components are engineered for durability and performance benefits from Flowmaster’s reputation. It is a complete kit that offers improved exhaust flow, a bold sound profile, and a straightforward installation process, making it a popular choice for Tundra owners seeking an aftermarket upgrade.
