    Powerful and sleek, the Honda Civic Si is highly praised by many drivers. Providing you with superior performance, it also offers utmost reliability and a stylish, recognizable design. However, if the power of your Civic is still not enough for you, and you seek to boost it, performance exhaust parts designed to increase exhaust flow can help. It's recommended that you reconsider the whole exhaust system including the manifold, muffler, catalytic converter, and diameter of the pipes. Replacing the factory exhaust manifold with the header, you take an important step to achieve maximum efficiency.

    The factory exhaust manifolds are generally quite restrictive, which creates obstacles for exhaust flow. Aftermarket headers are devised to reduce these restrictions on the way of the exhaust gases. This effect is achieved thanks to an advanced construction featuring individual tubes for each cylinder. Every exhaust pulse flows freely from the cylinder port without interfering each other, so the gases create less back pressure and thus require less useful energy to come throughout the entire system. Our virtual shelves are stoked with Honda Civic Si performance headers crafted with the use of the latest technologies to ensure trouble-free installation and durability.
