I have used that b hut it always comes back blue. The only option is to find double walled headers, (Non- existent) or have them ceramic coated. *I did use multiple applications of high heat black paint on the inside of the 6 headers on my CBX and it seems to have done the job. Set up a jig for all the headers, spray high heat paint in header, let dry, repeat. It didn't;t clog the mufflers and keeps the discoloration to a min.2strokejohnny wrote:have you tried this ? worked on my Bonnie but have to do it yearly
