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 is constructed from mandrel-bent 2.50-inch stainless steel flowing into a specially designed Super 40™ Series muffler for a moderately aggressive exterior tone and a moderate interior tone. The system finishes with dual 2.50-inch mandrel-bent stainless tailpipes and a pair of 3.00-inch polished 304 stainless steel tips, with 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 Lifetime 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. For those who prefer full aluminized steel construction with a 3-year Limited Warranty, check out exhaust system part# 17473.
