Header wrap, or a high temp dynomat type stuff. The header wrap honestly probably doesn't do anything for sound deadening, but it MIGHT take some frequency out of the exhaust and that could appear to your brain as more quiet.
Here is some sound deadener that's good to 800*, I'd email them to see how it would do taped up to the exhaust. It comes in strips which would be tits for you. http://store.secondskinaudio.com/the...6-1-5-sq-feet/
