Subaru Impreza Headers are really nothing more than a fancy way of saying Subaru Impreza Custom Exhaust Manifold. It makes a difference, though. Custom headers allow for faster movement of exhaust gases out of the cylinders and through the exhaust system.
This in turn allows raises your engine's horsepower potential. Most headers, or exhaust manifolds, are made of heavy cast iron in order to stand up to the preternaturally hot temperatures of fresh exhaust exiting the cylinders.
The headers used on virtually all street machines have collectors. It is here that exhaust gases are "collected" from the cylinders before they move on to the rest of the exhaust system. The other kind of header, called the "zoomie," is used primarily on formula race cars and inline, water-cooled prop engine aircraft. They are not legal for for street use. However, there are custom Subaru Impreza Headers available - such as the Borla header - that use the "zoomie" concept in a way that can improve power and low-end torque by as much as 15% while keeping your vehicle street-legal.The Borla header comes with a 1,000,000 mile warranty, and you can get it here at the lowest price anywhere - we guarantee it!
