Review FLOWMASTER Cat back System Dual Rear/side Exit American fits THUNDER

Introducing the Flowmaster American Thunder 17468 Cat-Back Exhaust System, a high-performance aftermarket exhaust solution designed specifically for American muscle cars. This dual rear/side exit exhaust system is engineered to deliver an impressive blend of power gains, improved exhaust flow, and a throaty, resonant exhaust note.

The heart of this system is a 304 stainless steel construction, ensuring durability and resistance to rust and corrosion. The Cat-Back design replaces the entire exhaust system from the catalytic converters to the rear bumper, allowing for uninterrupted exhaust flow and maximum power output.

Each exhaust tip features a polished stainless steel finish, adding a touch of elegance and style to your vehicle's rear end. The dual rear and side exit design not only provides an aggressive appearance but also increases exhaust flow efficiency by providing multiple exhaust paths.

The American Thunder 17468 system utilizes Flowmaster's proprietary muffler technology, which includes 18-inch serpentine tubing and 40-cell SuperNight mufflers. This design provides a deep, resonant exhaust tone without being overly loud or obnoxious.

Installing this system is a breeze with the included hangers and hardware, making it a popular choice among DIY enthusiasts and professional installers alike. Additionally, the system is CARB-legal, making it a viable option for those who live in California or other areas with strict emissions regulations.

In summary, the Flowmaster American Thunder 17468 Cat-Back Exhaust System is a premium aftermarket exhaust solution that delivers power gains, improved exhaust flow, and an impressive exhaust note. With its durable stainless steel construction, elegant design, and easy installation process, it's a must-have modification for any American muscle car enthusiast.
