Performance Headers: Materials and Finishes

Performance headers are an important part of any aftermarket exhaust system. Headers attach to the engine and withdraw exhaust gasses from the combustion chamber. Performance-oriented exhaust headers are designed to make this process as easy and fast as possible and decrease back pressure.

Usually, exhaust headers are made from the following materials:

  • Stainless steel;
  • Steel;
  • Cast iron;
  • Titanium.

Stainless steel won’t rust or corrode with time. The only thing that may happen to it is color changes (headers can turn blue closer to the engine under the influence of high temperatures).

Performance Headers

Cast iron headers are good in terms of heat absorption, so high temperatures do not distribute that much to other nearby components.

Titanium exhaust headers are significantly lighter, than headers made from all other materials, and this material is widely used in aeronautics and air jet production. Headers made from traditional steel may corrode with time, that’s why they are usually coated with chrome, ceramic coating or paint.
