Those are not the ceramic coated headers George , and that would be a mistake unless you want them to rust and have heat problems. THY-530Y-C is the model he wants. If I remember correctly, the coating is about $90, but I think I paid less than $512 on the East coast. I did buy mine when they just started ceramic coating, so the price may have gone up. Check out some of their listed dealers. They would get them at a discounted price, and they may be less expensive that way . Even at $512 the coated headers are worth it IMHO, but I have never heard anyone include sales tax in a quote.
