I've used high-temp exhaust paint and it peeled off as well. I then tried barbeque paint and it has not peeled off at all. I've used it on the two-stroke exhausts on my snowmobiles and the headers on my 400 in my '53. The barbeque paint has worked with no problems. Good preperation is a must for whatever you use
I was going to suggest bbq black as well. Even the high temp engine paints aren't really meant for headers, they claim 1500 but being a coating, they don't work as well. Bbq black is almost like a black etch primer in a way, it eats itself into the metal making it more durable. I'm assuming that since you want to paint them you're not wanting to spend the money on a set of ceramic coated, or Jet Hot coatings either.

duplicolor has a paint supposedly meant for headers and is "with ceramic" but only rated to 1200*.....intermittently.

if you dont care which color they are you can use the high temp white. for some reason it seems to be the best for longevity. the way to apply it so it will stay is to take a torch and get the headers nice and warm then spray a good coat of the paint on it.
paint inside and out- so you will want to clean the inside with some sort of aggressive detergent and then I'd soak rags with ospo acid to etch it real good then maybe use the bbq stuff on a rspongeand push-pull through a couple/4 coats. headers often rust from the inside out.
i wished i would have used some of that paint like the bbg paint, but in ford blue. I painted my new motor and its still blue but some rust is starting to come through. It could also be that the mud dried on it and caused it. How much does that bbg usually run??
thanks guys the hooker supercomo. look great . first i cleaned them out with seafoam and bottal brush sandblasted them then heated them a used duplicolor
4 coats in and out thay look great thanks again
Are you guys heating the headers up after the paint is applied? it seems most of the paint companies recommend that as part of the curing process. I crank mine up but I don't bring them up to full temp too soon in the drying/curing process. They
