I spent about 2 hours grinding to remove the casting flashing then took them to the ceramic coater and had them coated. Went with the cast iron color look but from what I understand there is a chrome type coating that looks like most of the ceramic coated headers. Haven’t run the engine yet but hope they will last as good as the headers I’ve used in the past. There are pictures of my exhaust manifolds on my build thread.
