The header is an assembly engineered to collect the exhaust gas from multiple cylinders and combine those flows into a single pipe, in most production engines. Headers are usually made of cast iron in stock production cars and may come with material saving design techniques. Most production header designs are built to use the least amount of metal, to occupy the smallest space necessary or have the lowest production cost. These design restrictions usually result in a design that is cost effective but that does not do the most efficient job of venting the gases from the engine.

Generally, inefficiencies happen because of the nature of combustion engines and their multiple cylinder banks. The exhaust leaves them at different times since cylinders fire at different times. This difference in time can produce pressure waves when gases coming out from one cylinder are not completely gone from the exhaust system by the time another one does. This creates a backpressure and restriction in the exhaust system of the engine, which can restrict the real performance possibilities of the engine.

Generally, headers are produced by aftermarket automotive companies, like the DC Company but sometimes can be purchased from the high performance parts department at car dealerships, like us. Most car performance enthusiasts generally buy aftermarket headers made by companies, which are primarily focused on producing cost effective but well designed products for their vehicle. Headers can also be custom designed by a custom shop. Due to the advanced materials that some aftermarket headers are made of this can occasionally cost a lot of money, but this will not be the case with the DC headers since they are high quality but cost effective at the same time.
