This American Thunder Cat-back exhaust system is designed for the 2015-2022 Dodge Challenger Hellcat and Demon with the 6.2L engine, the SRT392 and R/T Scat Pack models with the 6.4L engine, as well as the 2017-2021 R/T with the 5.7L engine and is perfect for the person looking for an aggressive exterior sound level while maintaining a moderate interior sound with all of the performance benefits that you would expect from Flowmaster. This bolt-on 409S stainless steel system features mandrel-bent dual 3.00-inch tubing flowing into our exclusive Scavenger Series X-pipe assembly for maximum power and a deep unique tone. The tubing then flows into a pair of specially built Super 40 Series mufflers and the tailpipes include dummy valve stands to fool your factory actuators into thinking theyre still operating the OE valves. This way, you always have that wide-open sound and performance without throwing a code. The stainless steel tailpipes are finished off with Quad 3.50-inch polished 304 stainless steel tips exiting within the rear bumper valence. The system uses the factory hanger locations for an easy installation and is covered by our Lifetime Limited Warranty. Includes all necessary parts and hardware for installation. Note: This system eliminates the Factory Exhaust Valves and provides Dummy valve stands so the Factory Actuators still work without throwing off a code.
