Review FLOWMASTER Cat back Exhaust System fits FORCE

The Flowmaster 817509 Force Cat-Back Exhaust System is a high-performance aftermarket exhaust solution designed to enhance the sound and overall performance of your vehicle. This system is specifically engineered for select Ford, Lincoln, and Mercury models with a cat-back configuration.

The heart of this exhaust system is the 304 stainless steel construction, which ensures durability and resistance to rust and corrosion. Each component, from the mandrel-bent piping to the polished tips, is meticulously crafted to provide an exceptional fit and finish.

The Flowmaster Force series mufflers employed in this system utilize a unique 10-inch Serpentine Core design.

The result is an increased exhaust velocity, which leads to improved engine performance and power output.

This cat-back exhaust system also features a free-flowing design that reduces back pressure, allowing the engine to breathe more efficiently. The reduced back pressure also leads to improved fuel economy and a smoother, more responsive driving experience.

One of the most notable features of the Flowmaster 817509 Force Cat-Back Exhaust System is its distinctive sound. The system's unique muffler design produces a deep, resonant exhaust note that is both aggressive and refined. The sound is a testament to the system's high-performance capabilities and is sure to be appreciated by any enthusiast.

This exhaust system is a direct replacement for the factory exhaust and comes with all necessary hardware for installation. The system also includes a set of polished, 4-inch tips that provide a stylish and premium appearance.

In summary, the Flowmaster 817509 Force Cat-Back Exhaust System is a high-performance aftermarket exhaust solution designed to enhance the sound and overall performance of select Ford, Lincoln, and Mercury models. The system features 304 stainless steel construction, a unique 10-inch Serpentine Core design, and a free-flowing design that reduces back pressure. The result is improved engine performance, power output, fuel economy, and a distinctive exhaust note.
