Horsepower is governed by the amount of cool air coming into the engine, the amount of fuel added, and finally, the ease at which the exhaust can be pushed out of the exhaust chambers. While the entire exhaust system is capable of slowing the flow of the exhaust, what can be most detrimental is a restrictive set of Pontiac headers, as it is the first place into which the exhaust flows. A pipe at each cylinder transports the exhaust down to the collector tubes of the Pontiac headers. In order to have equal pressure from each cylinder, it is necessary for the tube coming from each cylinder to be the same length by the time they reach the collector tubes. This introduces many bends into the Pontiac headers, and wherever there is a bend, there is a chance for the exhaust to slow. In, addition, the collector tube must be capable of combining the gasses from each cylinder efficiently. Often, the stock Pontiac headers perform these jobs adequately, but there is always room for improvement. Our online catalog has a full selection of high-performance Pontiac headers to choose from, and they are at great prices. With computer designed bends, and a large collector tube, the Pontiac headers we sell have been proven on the dynamometer to add a significant amount of power. They will bolt up to the stock cylinder heads with no modifications, making them easy to install. Our Pontiac headers are made of superior materials for a long life, and come with a full manufacturer's warranty. You can order a set of sharp looking, performance enhancing Pontiac headers online or with our toll-free telephone number, available 24 hours a day.
