This Flowmaster® Outlaw Cat-back exhaust system is designed for the 2015-2020 Dodge Challenger SRT 392 and R/T Scat Pack models with the 6.4L engine, as well as the SRT Hellcat with 6.2L engine. The system is perfect for the person looking for a very aggressive exterior sound level when hard on the gas while maintaining a moderate tone when cruising. System features include 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 include high-quality active exhaust valves ready for your factory actuators. The system is then finished off with quad 3.50 in. 304 stainless steel embossed tips for a muscular look. 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.
