For the person who wants the aggressive look of a NASCAR race truck along with all the benefits that a Flowmaster Cat-back exhaust system provides. D.O.S.S.

The American Thunder systems deliver a moderate to aggressive interior and exterior tone and are suited to the enthusiast who wants their performance to be heard. The exhaust system is constructed from 3.00-inch mandrel-bent aluminized steel tubing flowing into a Super 40 Series performance muffler for a deep powerful sound, then is finished off with dual 2.50-inch tailpipes and a pair of 3.00-inch polished stainless steel tips.
