This Flowmaster® Outlaw Cat-back exhaust system is designed for 2008-2014 Dodge Challenger SRT8 models with the 6.1L or 6.4L Hemi engine, and are perfect for the person looking for an aggressive interior and exterior sound level at all times. The system includes dual 3.00 in. mandrel-bent stainless steel tubing flowing into our exclusive Scavenger Series® X-pipe for a deep unique sound while making maximum power. The tubing then runs into a pair of race-proven Outlaw® Series mufflers and the tailpipes utilize the factory hanger locations for an easy installation. They are finished off with polished rectangular 304 stainless steel tips for a muscular look to match the lines of the Challenger. The system is covered by our Lifetime Limited Warranty and includes all necessary parts and hardware for an easy installation you can do at home.
