No, I don't, but there was a thread on here one time about after market steel braided lines... not sure if that helps..
Another idea, something that I want for my s4, is the foggy style pipes in the coolant system... is there a foggy owner out there that can tell me if the whole system is pipes, or just some of it? If so, you could send those to jet hot coatings and I think they do colored coatings, or just powercoat them.
