I just picked up a set of 321 stainless headers for my car that might see a one or two HPDEs a year. I'm considering getting them ceramic coated instead of eagerly installing them this weekend. I called a local shop yesterday and they quoted me a little over 250 for cerkote high temp ceramic. Would you that are knowledgeable/experienced in this area say that the coating is worth it for the E46 M3? Are some coating brands preferable to others/are some utter crap?
