TTI Shorty Headers - 'White Lightning' Ceramic Coated
My friend Rob said he's bringing them to Carlisle for me.
I assume he'll be in the vender section since he owns a shop.
The Swain ceramic coating was applied with plazma spray (like a flame) creating a thick coat directly bonded to the metal. It will insulate the heat from the pipes as good as, and probably better than any other type of coating.* It can be painted if you want. A bright finish, like aluminium, may further reduce in radiated heat.
