American Thunder Cat-Back Exhaust System 2009-2014 Dodge Challenger Rt With 5.7L Hemi Engine Aggressive Sound - Flowmaster - 817479

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 Flowmaster American Thunder exhaust system features dual 2.50-inch mandrel-bent tubing flowing into our exclusive Scavenger Series X-pipe design for maximum scavenging performance and a deep unique tone.

The stainless tubing then flows into a pair of specially selected Super 40 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 exit into the factory rectangular exhaust tips. 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.
