Is the upgrade to ceramic headers worth anything performance wise or is it strictly visual? Is it worth the $ to buy ceramic?
I've even seen ceramic coating rust if not kept clean. The big deal is that it keeps heat inside the headers, which hype says promotes some kind of magical thing that could maybe make 1hp more. The "worth it" is that they'll last longer and look good longer and keep under hood temps lower. If you shell out the cash for true Jethot coated headers, they're coated inside and out and will last a long time (especially if the headers are stainless to begin with before being coated).
I had FRPP stainless headers on my white car for 7 years and they started rusting within a year. By the time I took them off, they looked really ratty. Just surface stuff, but still... I replaced them three years ago with FRPP JetHot coated ones and they still look like the day I installed them. If you get them, inspect the coating for damage. Any little chip will invite rust to get a foot hold. The first set Summit sent me had a big chip in the coating. They immediately replaced them for me without any questions and the next set arrived perfect.
