The Flowmaster Outlaw SS Cat-Back Exhaust System is a high-performance exhaust upgrade designed for the 2009-2021 Toyota Tundra with 4.6L, 4.7L, or 5.7L engines. Constructed entirely from stainless steel, this emissions-legal system features an aggressive dual inlet Super 10 Series muffler that flows into large 3.00-inch dual tailpipes, delivering maximum sound and performance. The system enhances exhaust flow for increased horsepower and torque while providing a bold, aggressive exhaust note both inside and outside the truck. Large 4.00-inch black ceramic coated double wall stainless steel tips finish the tailpipes, adding durability and style. The kit includes all necessary hardware for straightforward at-home installation, making it a reliable upgrade for enthusiasts seeking a deep, commanding sound and improved exhaust efficiency.
This bolt-on system is compatible with 2009 models built after August 2008, specifically fitting 2WD and 4WD versions with a 145-inch wheelbase. It is designed for trucks with either dual rear exits or dual exits behind the rear tires, which is especially beneficial for towing applications. Not suitable for regular cab/short bed or double cab/long bed models. The system provides a performance-oriented upgrade suitable for street driving, daily use, and towing, offering maximum sound and flow benefits while maintaining emissions compliance. All components are included for easy installation, backed by Flowmaster’s Lifetime Limited Warranty.
