Enhance performance and sound with durable stainless steel construction.
The Flowmaster American Thunder cat-back exhaust system is engineered to improve exhaust flow and performance for trucks equipped with a factory dual exhaust option. Constructed from 409 stainless steel, the system features mandrel bent tubing that maximizes exhaust gas flow while ensuring durability. The included Super 40 Series muffler produces an aggressive to moderate sound level, enhancing the driving experience while delivering significant performance gains. Testing has shown increases of up to 18 horsepower and 14 pound-feet of torque at the rear wheels, making this system a valuable addition for performance enthusiasts.
This exhaust system is designed for easy installation, utilizing all existing factory hanger locations and including complete hardware and installation instructions. The 3-inch diameter tubing is complemented by large 4-1/2 inch black ceramic coated tips that provide a stylish finish, filling the bumper cut-out more effectively than factory tips. With no welding required and an estimated installation time of just two hours, this cat-back system is suitable for home installation, allowing users to enhance their vehicle's performance and aesthetics with minimal effort.
