my twisties are coming apart on me at the collectors and i need to wait till spring before buyin new 1's. anyways, i've got some shorties i sent to be welded up dry, have the o2 bungs installed, cut the collectors down and they should be back tonite. the chrome is shiat and these headers aren't worth coating so what's the best black paint that'll stay on a blown boat's headers?? i don't think the hi-temp ceramic stuff duplicolor sells will stay on them. egt on a blower motor gets up to 1700-1800 at times.
anybody have any luck with a certain brand??

I've used VHT before and it lasted OK on a regular engine. Just dont put it on too thick. You dont want it to hold heat or it will burn right off. Just enough to get some color...

You do realize your pistons will melt before 2000 degrees and if your headers are that hot your burning fuel in them as well as your cylinders.
Just my .02

I've had no good luck with any paints.....Just coatings.
Haven't tried them all but I've tried a bunch.
Life sure was different before the coating companies came about.

I've had great luck with some high temp VHT. I've only used the 1200 degree cans.
I used to always use the flat black for exhaust manifolds. But I also used the silverish one on some Hooker headers. I put it on real light about a year ago, and to this day people still ask where the ceramic coating was done. They look real good still, but those were car headers. Not sure about what water injection would do to it

I've used the same stuff on a few automotive headers. Be casreful installing as if you get fingerprints on it the paint will burn in that area. Atleast it did on mine.
