    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. The American Thunder exhaust system bolts onto the back of the catalytic converter and is starts with a Super 50™ Series performance muffler for a moderately aggressive exterior tone and a moderate interior tone. The system finishes with dual 2.50-inch tailpipes and polished 3.00-inch stainless steel tips, and your choice of tailpipe exits either straight out the back for a muscular look, or exiting behind the rear wheels which is ideal for towing. The system uses the factory hanger locations for an easy installation and is covered by our 3-year Limited Warranty. 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.
