Exhaust systems are made from metal to provide the required durability and resistance to heating, cooling and exposure to the elements. However, there are many different types of metals (and grades of individual metals). A wide range of metals can be used in your exhaust, depending on the type of system you are using.
Types
- Aluminized steel: Aluminized steel is an attempt to make the metal more corrosion resistant.
- Stainless steel: Several grades of stainless steel are used on aftermarket systems.
- Cast iron: Cast iron is used mostly in stock exhaust systems
