Header Pipe Discoloration - Possible Solution

[The Spaceman_imp]

I've just about given up on this one. I had an idea that I'd use an exhaust wrap to hide the pipes. DEI has a new wrap that's really slick; it looks a bit like carbon fiber, and compared to the old stuff is really easy to use. Unfortunately the pipes are so close together near the bottom that the wrap won't fit between them. I've got the materials if anybody else wants to try it.

There was a guy at the boatyard where I used to keep my catamaran who had this gizmo that would gold-plate metal (you had to provide or pay for the gold). I'm thinking that might be a cheaper option than buying the aftermarket exhaust kits...
