Description
The Flowmaster American Thunder Cat-Back Exhaust System is designed for 2015–2023 Dodge Charger SE, SXT, and 2015–2020 Chrysler 300S with 3.6L engines. This system delivers a bold, aggressive exterior sound while keeping interior noise at a moderate level, making it perfect for daily driving and performance applications.
Constructed from durable 409 stainless steel, the system features dual 2.50-inch mandrel-bent tubing flowing through an exclusive Scavenger X-pipe for maximum performance and a deep, distinctive tone. A pair of Super 44 performance mufflers are paired with specially-tuned resonators to minimize interior drone, providing an ideal balance between performance sound and comfort.
The exhaust is finished with 2.50-inch polished stainless steel tips that exit through the factory rear bumper valence for a clean, factory-fit appearance. Installation is straightforward using all included hardware and factory mounting points. This system is backed by Flowmaster’s Lifetime Limited Warranty.
