With its classic sound, Flowmaster’s 817741 American Thunder Cat-Back System for the 2015 Dodge Charger SE/SXT and 2015 Chrysler 300S with 3.6L V6 engine features mufflers tuned to deliver more power, torque, throttle response, and mileage. Best of all, these exhaust systems take sedate vehicles and deliver the great performance tone that muscle car fans love. American Thunder is the most authentic Flowmaster muffler sound available.
