For the person who is looking for a complete cat-back dual exhaust system with a moderately aggressive exterior tone and a moderate interior tone. With easy fit in mind, the FlowmasterÆ American ThunderÆ exhaust system features dual 2.50-inch mandrel-bent stainless steel tubing flowing into our exclusive Scavenger SeriesÆ X-pipe design for maximum scavenging performance and a deep unique tone. The stainless steel tubing then flows into a pair of specially selected Super 40Æ Series performance mufflers, which offer more internal volume than other brands mufflers and easily handles the flow demands of the Hemi engine. The system uses the factory hanger locations and the mandrel-bent tailpipes are finished off with a pair of highly polished 304 stainless steel 4.00-inch diameter tips exiting straight out under the rear valance. Designed for an easy fit, these systems include all necessary parts and hardware for easy installation you can do at home. Covered by our Lifetime Limited Warranty. Notes: Includes all wheel drive models.
