Mine get pretty warm already...over 500F after a few minutes of idling on the lift according to my IR temp gun so I wouldn't expect them to be that much hotter. I would still ceramic coat them with a nice satin black finish to help with heat, but I'm tired of pulling them off every couple of years to re-coat due to rust break through on the mild steel headers so I want to try stainless.
