The Dougs Header you have chosen is raw, not Metallic Ceramic Thermal Barrier Coated (MCTBC) which is the standard finish on all Dougs Headers. The picture you see is the same header with MCTBC which protects and extends the life of headers by creating a thermal barrier that significantly lowers underhood temperatures and protects the substrate metal from thermal fatigue. It also provide corrosion resistance to protect it for years to come.
Please see our online catalog for specific application information.
