About this product

Part #: 817778

Flowmaster's American Thunder Cat-back exhaust system for the 2017-2019 Dodge Charger R/T with the 5.7L Hemi engine is perfect for the person looking for an aggressive exterior sound level with all of the performance benefits that you would expect from Flowmaster. This bolt-on 409S stainless steel system features a dual 3.00 inch mandrel-bent Scavenger Series X-Pipe for maximum performance and a pair of specially designed Super 40 Series mufflers with 3.50 inch internals for maximum power and exterior sound quality, but with a moderate but pleasant interior tone at cruising speeds. Other features include dual 3.00 inch mandrel-bent tailpipes which are designed to re-use the factory exhaust valves and exit in the factory exhaust tips located in the rear valance. The tailpipes are a two piece design and have no resonators. This system includes all necessary parts, hardware and instructions for an easy installation.
