Exhaust Header Best Sellers! Use Shop By Vehicle Above To Find Yours!
The Exhaust Header serves the purpose of decreasing the exhaust gases' back pressure to improve engine efficiency. It is usually made of mild steel or stainless steel. The header is fitted to the cylinder heads. In vehicles with an exhaust manifold, exhaust gases from all the cylinders reach the exhaust system through a single exhaust manifold, resulting in the build-up of back pressure. To overcome this, each cylinder is fitted with its own exhaust pipe. These pipes then join together to form a collector.
During the exhaust stroke, exhaust gases are expelled out of the engine cylinder. These gases pass through the respective exhaust pipes into the collector. This process results in a considerable decrease in back pressure as the engine needs less power to expel the exhaust gases. Depending on the engine configuration, there may be one or more exhaust headers.
Over time, the exhaust header may break or develop cracks, resulting in a leak of the exhaust gases. A damaged exhaust header could result in an emission of poisonous exhaust gases which are hazardous. Further, it will fail to minimize the back pressure, which will cause a reduced engine performance. If you are looking to replace a faulty exhaust header, you have come to the right place.
