Description
Overview
The Flowmaster American Thunder Cat-back Exhaust System is engineered for the driver who wants an aggressive exterior sound level backed by real Flowmaster performance. Built specifically for the 2017-2023 Dodge Charger R/T and Daytona models equipped with the 5.7L Hemi engine, this bolt-on system transforms the way your Charger sounds and breathes without the guesswork of a custom fabrication. Constructed from durable 409S stainless steel, it is designed to deliver lasting performance and that unmistakable American Thunder tone.
At the heart of the system is a dual 3.00-inch mandrel-bent Scavenger Series X-Pipe that promotes maximum flow and scavenging for improved performance. Exhaust gases feed into a pair of specially designed Super 40 Series mufflers featuring 3.50-inch internals, tuned to produce maximum power and a rich, aggressive exterior sound quality while keeping a moderate, pleasant interior tone at cruising speeds. It is the balance serious enthusiasts look for: bold when you get on the throttle, comfortable on the highway.
Key Benefits
This dual tailpipe system uses dual 3.00-inch mandrel-bent tailpipes engineered to re-use the factory exhaust valves and exit through the factory exhaust tips located in the rear valance, preserving a clean, integrated OEM appearance. The tailpipes use a two-piece design with no resonators for a more direct, uncompromised note. Because the system mounts using the factory hangers and includes all necessary parts, hardware, and instructions, installation is straightforward for a true bolt-on upgrade.

This is a complete dual-tailpipe cat-back kit, with the mufflers included as part of the system.
