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 exhaust system is constructed from 3.00-inch mandrel-bent stainless 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. Includes all necessary hardware, instructions and is covered by our Lifetime Limited Warranty.
