Tomei Equal Length Exhaust Manifold

A quality exhaust manifold is one of the best exhaust modifications you can perform on your Subaru WRX/STI. If you have ever removed or had a chance to examine the factory exhaust manifold, you can see that there is much room for improvement. It is also a very heavy component.

Seamless Development for Maximum Performance

Tomei has taken advantage of this opportunity by designing a state-of-the-art turbo header that features durable stainless steel technology that can sustain the heat and abuse generated by the turbocharger. The smooth bends in the tubing provide an unobstructed flow path for the exhaust gases to escape which will increase the horsepower, torque, all while reducing the turbo lag while improving the throttle response. Note that this is an equal-length design so this will provide your vehicle with a very aggressive 4-cylinder sound.
