What is an appropiate material for this application?
What temperature range will this component be subjected to?

RE: Turbo charged engines - exhaust manifolds
Cast Iron is commonly used. It has multiple advantageous properties in this environment, and is the OEM choice. After the collector the connecting tubing is commonly 439ss.
There are various aftermarket manifolds available. Most are 304ss (hopefully L grade). Some are manufactured using the more apropriate 321ss.
The race teams use inconel type headers and exhaust systems. They also have Anti-Lag fitted. Some aftermarket companies also have available inconel alloy components.

I love materials science!

I assume it will be an SG iron, but are the high silicon /molybdenum required?

The thin tubing distorts some, but that is getter than failing in thermal fatigue.
