What do Exhaust Header do??

Exhaust headers are designed to boost horsepower, torque, and improve your vehicle's sound, especially for your 2006-2011 Honda Civic Si 8th Gen. Replacing or upgrading your headers and exhaust system is an effective way to increase engine performance. Want your 8th Gen Civic Si to sound more aggressive, like an American muscle car? This header can add up to 8-20 horsepower and significantly enhance exhaust tone.

Installing a high-performance exhaust system also improves fuel efficiency by about 0.5 mpg. While that may seem small, consider this: If gas costs $3 per gallon and you drive 15,000 miles a year, you could save around $85 annually on fuel. In five years, that’s enough to nearly pay for a complete cat-back exhaust system!

Exhaust Header VS Manifold, which is the better choice??

The structural differences between exhaust headers and manifolds lie in material and design. Exhaust headers are made from lighter, thinner steel, whereas exhaust manifolds are constructed from thick iron. Headers are also longer, allowing each cylinder to have its own tube, which eliminates the back pressure created by manifolds. This results in improved performance, as the gases exit the engine more efficiently. For your 2006-2011 Honda Civic Si 8th Gen, upgrading to headers offers better performance by reducing back pressure and boosting horsepower and torque. Therefore, exhaust headers are the superior choice over traditional manifolds for maximizing your engine's potential.
