Flowmaster's American Thunder Cat-back exhaust system for the 2015-2018 Dodge Charger SRT 392 and R/T Scat Pack models with the 6.4L engine, as well as the SRT Hellcat with the 6.2L engine, 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 a 3.00 inch Scavenger X-pipe assembly that runs into a pair of specially built Super 40 Series mufflers. The system uses 3.00 inch mandrel bent tubing for maximum performance and is then finished off with 4.00 inch polished stainless steel tips embossed with the Flowmaster logo. The exhaust system is covered by Flowmaster's Lifetime Limited Warranty. Designed for an easy fit, this system includes all necessary parts and hardware for installation.
