The POR-15 company makes several products that they say will hold up to that temperature.

I believe you may want something able to withstand near 1000 degrees F. IIRC Rotary exhaust gets a bit higher than that and is not something id take lightly, thats why glasspaks dont last very long with a rotary pummeling teh pavement.

You just love plugging this stuff as much as possible, are they sponsoring you yet?
I used 1200* high temp paint on my tubular turbo manifold, Was holding up just fine till I decided to wrap it with header wrap.. after a few days started flaking off. But it seemed to hold fine till I wraped it.

Just a lil steal here for a sec. Arron on your engine rebuild the one that Archived, you used a glossy red paint, just wanted to know how well that is hold ing up and how it looks.
As for the posters question, I think that a painted mani would look kinda outta place, but its your car. The Advanced, Autozone paint sucks a big one. You can order hightamp paint that works really good from a deisel engine manufacturer. Not sure who makes there paint but everyone of there motors I have worked on, have almost all the paint on the block, head, cool side of the turbo, and sometimes the hot side. That stuff is as tuff as nails. Caterpillars paint seems to hold up the best, but the only colors I have seen from them are yellow and red.

I've used DEI brand silicone based exhaust coating with good results on my supercharged 3800 car, which gets hot enough a long run to make the manifolds turn purple. You do have to bake it at 400* to dry/set it, so unless you have a spare oven or understanding wife (or parents, in the case of much of this forum) you may not want to go that direction.
It's about 20 bucks a can, and a can is plenty. My entire exhaust from the catback forward is coated with this to keep corrosion away.

just to add......
Most high temp paints that people claim to be trash are not actually trash - they just did shitty prep work
with ANYTHING involving paint, high temp, regular base clear - prep is EVERYTHING....
just in case you missed that one:
PREP IS EVERYTHING
