A header is also called an "exhaust manifold," which refers to the hand-like shape of the device with its "fingers" reaching into the cylinders. When it comes to high performance, the exhaust system is the thing - and that starts with the header. More professional racing drivers, amateurs and performance auto enthusiasts choose Borla when it comes to exhaust components. Why? Because they simply do a better job for a much longer time. Installing a Borla Header will reduce fuel consumption and increase your engine's horsepower by up to 15%. The reason? Exhaust flow. When the engine doesn't have to work as hard to rid itself of waste products, there's more fuel and horsepower available to run the vehicle itself. Borla Headers, like all the company's exhaust products, are manufactured from aerospace-grade T-304 stainless steel, and will not succumb to rust or corrosion during the life of the vehicle - in fact, Borla backs all of their products with a one-million mile warranty, so you'll never have to replace a Borla Header. It's true that quality such as is found in Borla products costs more - but the investment will pay for itself many times over in the years to come.
