I just got a new set of headers but didnt have the money for ceramic. I will get tham sand blasted and painted with some high temp paint. Any suggestion on the brand of type of paint to use? What is up with thermal wrap? Why does it void the warrenty on most headers? What are the pros and cons of using it? Please just some quick info would be nice. Ill have some picks up shortly of how they turned out and hang on my car.
