This Flowmaster Outlaw Cat-back exhaust system is designed for the 2015-2023 Dodge Challenger SRT 392 and R/T Scat Pack models with the 6.4L engine, the SRT Hellcat with 6.2L engine, as well as the 2017-2021 R/T with the 5.7L engine. The system is perfect for the person looking for an aggressive exterior sound level at all times.

The system includes dual 3.00-inch 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 dummy valve stands to fool your factory actuators into thinking they're still operating the OE valves. This way, you always have that wide-open sound and performance without throwing a code. The system is then finished off with quad 3.50-inch 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. Note: This system eliminates the Factory Exhaust Valves and provides Dummy valve stands so the Factory Actuators still work without throwing off a code.
