The Flowmaster American Thunder Exhaust System is engineered for enthusiasts who demand a bold and aggressive exhaust note without sacrificing everyday drivability. Designed specifically for the 2011 to 2014 Chrysler 300 and Dodge Charger equipped with the 5.7L Hemi engine, this exhaust system delivers a perfect balance of performance and sound. It enhances your vehicle’s throttle response and power output while providing a distinctive exterior tone that commands attention on the road.
Whether you’re looking to upgrade your factory exhaust for improved efficiency or a more commanding presence, the American Thunder system offers a direct-fit solution that integrates seamlessly with your vehicle’s existing components.
This exhaust system combines quality materials and thoughtful engineering to deliver a superior driving experience. Key features include:
The Flowmaster American Thunder Exhaust System is constructed from premium 16-gauge stainless steel tubing that is mandrel-bent to maintain consistent diameter and maximize exhaust flow. This precision bending reduces restrictions and turbulence, contributing to improved engine performance. The stainless steel material offers excellent corrosion resistance, ensuring long-lasting durability and a clean appearance over time.
Specially selected mufflers are integrated into the design to produce the signature American Thunder sound—a deep, aggressive exhaust note that is powerful yet controlled. The system’s direct-fit design means it aligns perfectly with factory mounting points and exhaust components, minimizing installation complexity and eliminating the need for cutting or welding.
The American Thunder system enhances your vehicle’s performance by improving exhaust flow, which in turn helps increase throttle response and engine efficiency. The exhaust tone is carefully tuned to provide a moderate to aggressive sound profile that is assertive on the outside while maintaining a comfortable interior noise level. This balance makes it ideal for daily driving as well as spirited performance outings.
Installation is straightforward with this direct-fit exhaust system. It connects immediately after the factory catalytic converter and uses the existing hanger locations, allowing for a seamless bolt-on replacement of the factory exhaust components. All required hardware and hangers are included, enabling at-home enthusiasts to complete the installation without specialized tools or modifications.
This system is specifically designed to fit 2011 through 2014 Chrysler 300 and Dodge Charger models equipped with the 5.7L Hemi engine, ensuring precise compatibility and optimal performance.

ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
