on my 72 scout, I can either notch the firewall and run the exhaust down beside the trans, or bend a flange out of the way a little and run it over the top of the trans and back. if I wrap it with header wrap, do you think the trans tunnel will still get real hot? my buddy thinks it will heat the inside of the scout too much. I just figured i'd wrap it and then put some aluminum sheild spaced 1/2 away from the body sheetmetal to help dissipate the heat.
