[More Info]
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.
Features:
  • Exclusive Scavenger X-pipe for Maximum Horsepower and Torque
  • Large 3.00-inch Mandrel-bent Dual Exhaust System
  • Includes "Dummy Valve Stands" for OE Actuators
  • Quad 3.50-inch Polished 304 Stainless Steel Tips
