I've been running a set of Pacesetter headers with ceramic coating on a Nissan 720 pickup that's been my daily driver for a bunch of years. I've had those headers on it for at least 5 or 6 years, and they still look good and show no signs of rust or corrosion. They were $100 more than the same header uncoated, so I'd say that the ceramic coating is more than worth the money. I'll never have another set of headers without it.
