Is it possible to weld a bar to my manifolds, to prevent the use of a spreader tool to remove and install them?
Ya, it's a pain, because the exhaust usually gets undone 1 a month or so.if not preheated then cooled down properly you'll probably warp them more than they are now.
resurfacing might be needed after welding too...
is it that much of a pain to use the spreader? probably so, huh?
