I have a set of TBR 6/6 that I bought "used" last year. When I got them, the header's were already VERY blue. I decided to try my hand at painting them and see what happen's..... And they actually (IMO) look pretty darn good.
To strip/prep the chrome, I used a 4" wire wheel on my bench grinder. The way I have the grinder set up gave me plenty of room to move each pipe around. Here's a pic of both header's (before and after prep).

After stripping the chrome, I taped everything and hung them up in the garage. Then I got everything clean and ready for paint.
With the TBR's being single walled pipes, I was kinda worried about the heat. So I used "Rust-Oleum High Heat" spray paint. (2000* paint) Speaking of heat, they don't seem to get quite as hot as I thought. I've checked them several time's after rides (with a lazer thermometer and the bike still running). The hottest temp I found on any of the pipes was a cool 540*. (right below the flange on the back pipe.) The rest of the pipes were running 480-500*. They would get cooler as I went down the pipe. (I understand temp's can be different from bike to bike depending on how the carb's/engine is tuned.)
Here's a pic of the finished pipes before being mounted.

...and after mounting.


I've been on several rides, and they still look "just painted". I guess time will tell on how they hold up.
