Ram Pro line does a real good job. They have a few different ceramic coatings to chose from. Prices a reasonable, not the cheapest, but good work and good quality!
If I remember correctly he quoted me $300.00 ish ( more expensive then reg. headers because of all the twist and turns) for a set of Bassett Twisty's that where chrome and rusty!
