When I went to remove the crusty old headers, after screwing with them for about 20 minutes and remembering all that was involved with the installation, I took out the saw-zs-all, put on a Torch blade and they were out in 10 minutes. Not sure what's worse installing or removing? Probably installing as you try not to nick, ding or scratch the new ones...at least till you have to dent a tube for the steering box...
