HPC do you mean heat coating with paint?
Ceramic coating is much better but its expensive i.e a set of headers is like $400.
And if they are ceramic coated properly you can hold them after a drive.
Rubbed a set on a Cobra by accident, nothing at all, only alittle warm (stupid exhausts are on both sides! )
^^^supposed to be the same thing.. HPC i was referring to is ceramic....
dependent on who does it then? or different ratings?
curious... who did yours limbo? pm me?
i had some hurricane headers done before as well as a mate who got turbo pieces done... reduce in temp was noticable but wasn't enough and insides/outsides were done on our pieces.... i even researched it a few months later and saw some on dyno days and the exhaust bits still gets hot... just doesn't seem to reduce enough.
ideally i would have wanted this quality of work, but it was their top of the range stuff and i remember getting quoted around double what you said:

^^^mine sorta only looked like that and coating seemed thin.... i even chipped a bit off on the head flange just to see how thick and it was like ~1mm or less....
***EDIT***
i won't be a believer unless someone lets me hold theirs after serious driving and i don't burn my hand...
HPC doesnt charge $400 let alone double for a 4 cylinder car. Did you send them direct or through a 3rd party that ripped you off severly ?
