Review FLOWMASTER American Kit67 Ford Header fits THUNDER MUSTANG 1970

The Flowmaster American Thunder Kit-67 is a high-performance exhaust header system specifically designed for 1967-1970 Ford Mustang models. This header system is part of Flowmaster's American Thunder series, which is renowned for delivering powerful and throaty exhaust notes while improving engine performance.

This header system is constructed from premium 304L stainless steel, ensuring durability and resistance to rust and corrosion. Each header is meticulously crafted using advanced CNC technology to ensure precise fitment and excellent engine compatibility. The 1 5/8-inch primaries merge into 2.5-inch collectors, which then feed into 3-inch diameter exhaust pipes.

The Flowmaster American Thunder Kit-67 is designed to replace the stock exhaust headers, offering several benefits. It provides a significant improvement in exhaust flow, which in turn boosts engine performance by increasing horsepower and torque. This header system also reduces exhaust backpressure, allowing the engine to breathe more freely and efficiently.

Moreover, this header system comes with a unique exhaust note that is both powerful and distinctive. The exhaust gases exit through Flowmaster's patented "glasspack" mufflers, which provide a deep, rumbling exhaust tone that is sure to turn heads. These mufflers are also designed to minimize noise levels while maximizing exhaust flow, ensuring a balanced performance package.

Installing the Flowmaster American Thunder Kit-67 is a straightforward process, thanks to its bolt-on design. It comes with all necessary hardware, including new gaskets and bolts, making it an easy upgrade for enthusiasts looking to enhance their Ford Mustang's power and sound.

In summary, the Flowmaster American Thunder Kit-67 is an excellent choice for Ford Mustang owners seeking to elevate their vehicle's performance and exhaust note. With its premium construction, precise fitment, and powerful sound, this header system is a must-have upgrade for any Mustang enthusiast.
