Exhaust insulating wrap

My exhaust headers are getting very hot, (glowing red) since I added my Muzzy stainless full system. It is not an issue unless I get stuck in traffic or I am tuning it without a cooling fan. I'm thinking, (I know me thinking is a scarey thought) that exhaust insulating wrap on the exhaust headers for about the first 12 or 14 inches from the head on out may isolate the heat a little better. Any thoughts???? Thanx! I have checked and it is not running lean, if anything it's a little rich.
I've tried drinking 10 or thirty shots of Jim with beer and that doesn't help either.
