My headers are 2 1/4" ss which I polished to minimize radiant heat and I'm planning on jacketing with larger ss tubing . Thinking about ss wool between the header and jacket .

John;

If you can seal both ends of the header sleeve you could pull a vacuum on the space between the header tubes and the sleeves. That would prevent lots of heat loss. Not easy to do, though.

Just remember when you wrap that the headers need to be run hot to burn off the skin oils, any crap that touched or wiped on the wrap... If you paint with anything, they will smoke like crazy for a while.... it can be a good test for your firewall but will scare the crap out of folks with all the smoke.

McMaster Carr #9379k93 is 1/2" thick 3" wide soft ceramic pipe insulation with an aluminum jacket I'm going to insulate my streamliner headers with . Good to 2300 deg , $12 per 12 ft roll . #76035A65 is the 500 deg glass reinforced 2 mil aluminum foil tape I'm sealing the seams with . Low heat loss and won't any absorb oil .
