Description
Overview
The Flowmaster American Thunder Cat-back Exhaust System is built for the driver who wants a subtle custom appearance with all the performance benefits a Flowmaster Cat-back system provides. Engineered to deliver a deep, powerful exterior tone paired with a mild to moderate interior sound level, this American Thunder system gives you serious presence on the outside while keeping things fairly mellow inside the cab. It’s an aggressive-yet-moderate setup that sounds great without overwhelming your daily drive.
At the heart of the system is the Super 50 Series performance muffler, purpose-built to control resonance and keep the interior tone comfortable while still letting your engine breathe. Mandrel-bent 3.00-inch aluminized steel tubing flows into a specially designed resonator and on into the muffler, promoting smooth exhaust flow from the cat-back for improved throttle response, power, and mileage.
Key Benefits
Flowmaster designed this American Thunder system for both sound and function. The dual 2.50-inch tailpipe configuration is finished with 3.00-inch polished stainless steel tips for a clean, custom look at the rear of your 4WD vehicle. Because the system utilizes the factory hanger locations, installation is straightforward and every necessary part and piece of hardware is included in the kit.
