Like most things, there are variances in quality of 304 stainless. A good quality 304 is very resistant to rusting, where as the cheaper stuff from Asia is not. Why anyone would expect more from Fabspeed is beyond me. They make and sell the cheapest product on the market by a large margin, to expect a resulting product that exceeds being the cheapest by a large margin is silly.
I've had headers coated before, even by a small local coater and it makes a big difference in engine bay temps. I'm not a big fan of the inner coatings on street cars just because when the coating starts to fail and flake off, it can be ingested by the engine. Unlike jet engine and race cars, which are torn down for inspection routinely to avoid catastrophic failure events, street cars are completely ignored until a problem forces acknowledgement.
You can't go wrong with Jet-Hot, one of the original sources for exhaust coatings. They know how to prep the parts, how to lay the material down evenly and at the appropriate thickness and they also provide a warranty.
We've done some manifolds in a "bronze" type color and a few in a more traditional Silver. In my opinion for aesthetics, a Silver color is ideal.
