Description
Overview
The Flowmaster American Thunder Cat-back Exhaust System is engineered for the driver who wants a subtle custom appearance combined with the real-world performance benefits Flowmaster is known for. Built around 3.00-inch mandrel-bent aluminized steel tubing, this cat-back system promotes smooth, unrestricted flow from the catalytic converter back, helping your engine breathe more freely and work more efficiently. The clean silver pipe finish keeps the look understated, while a large 3.50-inch polished 304 stainless steel tip adds a purposeful, finished touch at the rear.
At the heart of the system sits a large-case, dual-inlet 50 Series Big Block performance muffler. This muffler is tuned to deliver a deep, moderate exterior tone that lets everyone know there is power under the hood, while keeping the interior tone mild to moderate so long drives and daily commutes stay comfortable. That balance makes it an ideal match for drivers who want improved efficiency and sound without an aggressive, droning cabin experience.
Key Benefits
Like all Flowmaster systems, this American Thunder cat-back is built to improve throttle response, power, and mileage. The moderate sound level and towing-friendly design make it especially well suited to work and towing applications, where usable performance and controlled volume matter most. Because it uses the factory hanger locations, installation is straightforward, and every kit ships complete with the parts and hardware needed to get the job done.
