Key Features:
Flowmaster’s American Thunder Cat-Back Exhaust System includes several advanced features designed to maximize performance and durability:
Construction & Design:
The system is constructed from 16-gauge aluminized steel tubing, which offers excellent resistance to rust and corrosion while maintaining structural integrity under high temperatures. Mandrel bending ensures smooth, unrestricted exhaust flow, reducing backpressure and improving engine efficiency. The Super 50™ Series muffler is specifically designed to produce a deep, aggressive tone without excessive drone inside the cab, striking a perfect balance for daily driving and spirited performance.
Tailpipes are routed using factory hanger locations, preserving the truck’s original mounting points and ensuring a secure fit. The polished stainless steel tips not only add a refined look but also resist discoloration and wear over time.
Performance & Sound
This cat-back exhaust system enhances your Dodge Ram 1500’s performance by improving exhaust scavenging and flow, which can lead to better throttle response and a more robust engine sound. The American Thunder system is tuned to deliver a deep, aggressive exterior exhaust note that commands attention, while maintaining a moderate interior sound level to keep cabin noise comfortable during everyday driving.
Installation & Fitment:
Installation is straightforward with this bolt-on system designed to fit all 2- and 4-wheel drive Dodge Ram 1500 models from 2006 to 2008, excluding MegaCab variants. The system uses factory hanger locations and includes all necessary hardware, allowing for a hassle-free installation that can be completed at home with basic tools. No cutting or welding is required, making it an accessible upgrade for most enthusiasts.

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!
