The Flowmaster American Thunder SS Cat-Back Exhaust System is a performance upgrade designed for 2009-2021 Toyota Tundra trucks equipped with the 4.6L, 4.7L, or 5.7L engines. Crafted from all stainless steel, this emissions-legal system features a dual inlet Super 40 Series muffler that flows into dual 2.50-inch mandrel-bent tailpipes, delivering maximum performance and a deep, aggressive exterior tone complemented by a mellow growl inside the cab. The system enhances exhaust flow and sound while maintaining durability and quality. It includes polished stainless steel 3.50-inch double wall tips, providing a stylish finish, and all necessary hardware for straightforward at-home installation.

This bolt-on exhaust system is compatible with 2009-2021 Toyota Tundra models with either 2WD or 4WD configurations, excluding regular cab/short bed or double cab/long bed variants built before August 2008. It is suitable for street driving and towing applications, offering performance benefits and a commanding sound profile. The kit provides two options for tailpipe exit configurations—dual out the back or behind the rear tires—allowing customization based on user preference. Designed for easy installation, it serves as a direct upgrade to factory exhaust systems, improving both sound and performance for daily driving or enthusiast use.
