Like JOG says, it won't be red for long. It'll turn different shades of burnt brown to faded red after a 100 miles or so.
Here's a suggestion.
-- When you first get it, install it on the bike exactly the way you want it. Use whatever clamps or other devices you'll use for the final installation. This'll make sure any scratches, or grooves, or cutting, or bending, whatever, will be done BEFORE you paint it.
-- Take it off the bike.
-- Sandblast the thing (and any other bracketry, etc., you want painted) so you get it down to a matte surface of pure metal,... no paint, no primer, no manufacturing residue, no coatings,....nada,... just the plain mild steel.
-- Don't touch it with your greasy biker fingers. The idea is to keep the surface white-room clean, with no substances on the surface at all. Just the plain steel.
-- Wrap it in a clean t-shirt or something for handling until you get it painted.
-- Hang it up on a coat hanger, whatever, outside where you can give it a few coats of paint without ever having to touch it.
-- Blow it off with compressed air to get the dust, t-shirt residue, flypoop, etc., off of it.
-- Give it three medium coats of Duplicolor Hi-Heat paint,.. letting it dry completely between each coat IAW the instructions. Looks like charcoal would be a good color for your bike.
-- Let it dry for a day.
-- Put it in the oven for an hour or so at 250 degrees. It'll be stinky, but it won't do anything to the inside of the oven.
-- Install it as before, being careful to not scratch it. There are no rattle can hi-heat paints that are tough like powder coating.
This procedure is one I arrived at after many many attempts at finding ways to keep some sort of a protective coating on the exhaust systems on the motors on my gyrocopters,... which get orange-hot during climbout. Dupli-color hi-heat paint (go figure!) is the only one that would last more than 10 or 20 hours.
