What do the WRX & WRX STI exhaust headers do?

Exhaust headers are essential performance upgrades for your WRX or STI exhaust system. They improve airflow from the engine, boosting horsepower and torque while enhancing engine efficiency. For the Subaru Impreza WRX & WRX STI, installing high-quality headers can add up to 8-20 horsepower, giving your car that aggressive, muscle-car sound. Additionally, headers and exhaust modifications can lead to improved fuel efficiency—around a 0.5 mpg increase—saving you money on gas over time. Over several years, the savings can even cover the cost of a full cat-back exhaust system, making it a great investment for performance and efficiency.

Exhaust Header VS Manifold, which is the better choice? 

The structural differences between exhaust headers and manifolds are the material and size. From the material, exhaust headers are made of lighter, thinner steel, while exhaust manifolds are made of thick iron. Exhaust headers are also longer than exhaust manifolds. When in use, exhaust manifolds create back pressure, which lowers performance. Because each cylinder of the engine is given its own tube, however, headers eliminate this problem; thus, allowing the gases to exit without the creation of back pressure. Therefore, exhaust headers are a BETTER choice than an exhaust manifold.

Replacing or upgrading your exhaust header is necessary for both engine performance and sound. Whether on or off the track, exhaust headers provide more horsepower and improved exhaust sound. FLASHARK offers many products to help you create your own custom engine headers. It's really easy and convenient to use: direct bolt-on, no modification needed.
