Description
The Flowmaster American Thunder® Cat-Back Exhaust System is engineered specifically for 2017–2023 Dodge Charger R/T and Daytona models equipped with the 5.7L Hemi engine and integrated rear exhaust bezels. This system is ideal for drivers seeking an aggressive exterior exhaust note while maintaining a controlled, comfortable interior tone during highway cruising.
Constructed from durable 409 stainless steel, this bolt-on exhaust system features dual 3.00-inch mandrel-bent tubing paired with Flowmaster’s Scavenger Series® X-pipe to improve exhaust scavenging, throttle response, and overall power. The system flows into a pair of specially designed Super 40® Series chambered mufflers with larger 3.50-inch internals, delivering a deep, powerful sound while minimizing interior drone.
The dual 3.00-inch mandrel-bent tailpipes are designed to re-use the factory exhaust valves and exit through the factory exhaust tips integrated into the rear valance. The tailpipes feature a two-piece design and do not include resonators. All necessary hardware and installation instructions are included, making installation straightforward using factory hanger locations.
