Then I would like to continue this thread with a question of my own. I'm trying to install the Energy Suspension Polyurethane master kit into my '73 240Z, but I don't know how to take the exhaust off. I don't want to remove the header and pull it out as one unit, but it's so crimped that I can't section it off. I'm also afraid of tearing it up when I muscle it because it's pretty rusty.
