The cost of getting headers coated will vary depending on the type of coating you select and the size of your project. Generally, a basic ceramic coating for performance headers can range anywhere from $200-$400. If you want to get more advanced coatings like titanium or stainless steel that can extend up to $600-$1000. The cost also depends on whether the header needs to be re-coated or if it’s a brand new set being done for the first time. Additionally, some shops may charge extra labor fees if they have to remove any parts in order to access the headers during installation. It's important to talk with your shop about all costs associated with this job so that you don't end up paying more than necessary down the line!
