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.
