Flowmaster American Thunder SS Cat-Back Exhaust For Tundra (99-06) (817425)

The Flowmaster American Thunder SS Cat-Back Exhaust System is a performance upgrade designed for the 2000-2006 Toyota Tundra trucks equipped with the 4.7L engine. Constructed with 16-gauge mandrel-bent stainless steel tubing, it features a specially designed resonator and a Super 50 Series performance muffler to produce a deep, aggressive exterior sound with a moderate interior tone. This emissions-legal system offers enhanced exhaust flow, durability, and a powerful sound profile, with dual 2.50-inch stainless steel tailpipes that utilize factory hanger locations for straightforward installation. It includes large 3.00-inch polished stainless steel tips and all necessary hardware, providing a bolt-on upgrade with minimal drone and a performance boost.

Designed to fit both 2WD and 4WD models across all wheelbases of the 2000-2006 Toyota Tundra with the 4.7L engine, this system serves as a direct replacement for the factory exhaust. It is ideal for street driving, daily use, and towing, offering a combination of sound enhancement and performance gains. The system is emissions-compliant and easy to install at home, with options for dual exit configurations—either behind the rear wheels or straight out the back for a more muscular appearance. The included hardware ensures a hassle-free installation, making it a popular choice for Tundra owners seeking a durable, high-performance exhaust upgrade.
