Description

For the person who wants the look of a traditional dual exhaust system with all the benefits that a Flowmaster Cat-back exhaust system provides. This dual out American Thunder cat-back exhaust system is the perfect choice with a 2.50-inch flanged pipe connecting directly to the catalytic converter and quickly transitioning to a full 3.00-inch mandrel-bent aluminized steel inlet tube flowing into a large case 80 Series Cross-flow performance muffler for a deep powerful sound. The system uses the factory hanger locations for an easy installation and features dual 3.00-inch mandrel-bent tailpipes exiting out the back and are finished off with dual 3.00-inch polished stainless steel tips for a muscular look and sound. American Thunder systems deliver a moderate to aggressive exterior tone with a mild-moderate interior tone and are best suited for the enthusiast who wants their performance to be heard. Like all Flowmaster systems, the benefits include improved throttle response, power and mileage. Designed for an easy fit, these systems include all necessary parts and hardware for easy installation. Comes with our 3-year Limited Warranty.
