Aftermarket Stainless Steel Exhaust Manifold

Aftermarket stainless steel exhaust manifold

Choose OEM or aftermarket exhaust manifold?

OEM manifolds are typically made from cast iron, so they are inexpensive. But because of production cost constraints, some OEM manifolds are susceptible to rust and corrosion.Aftermarket manifolds, on the other hand, are engineered for optimum engine performance. They can be made from stainless steel, coated mild steel, or aluminized steel. However, aftermarket manifolds are more expensive than OEM.

Choose Stainless steel, aluminized steel, or cast iron?

 here's a list of the advantages and disadvantages of the common types of manifold.

• Stainless steel: This kind of exhaust manifold is rust resistant. It can also retain its chrome-like shine for a long time. However, despite these benefits, stainless steel manifolds are more expensive than other types.
• Aluminized steel: By forming a layer of oxide, aluminized steel prevents corrosion. Although it's cheaper and lighter than stainless and cast iron, it easily rusts once the oxide layer is scratched or dented.
• Cast Iron: Stock exhaust manifolds are made from cast iron, so they are affordable. However, they tend to be on the heavy side, and they don't boost engine performance that much.
