What is the exhaust manifold made of on the Audi A5?

I am looking to replace the exhaust manifold on my 2015 Audi A5, but I'm not sure what material is used. Is it steel, cast iron, or something else?

The exhaust manifold on the Audi A5 is typically made of cast iron, which is a durable and heat-resistant material.

You can also find aftermarket exhaust manifolds for the Audi A5 made from stainless steel, which can offer better performance and longevity.

The exhaust manifold on the Audi A5 is usually a one-piece design, so be careful when installing and make sure all the bolts are tight to avoid any leaks or issues down the line.
