-My replacement (smaller) heat muff came in before vacation so it was time to install it. -Assembled per the instructions -Installed on the #1 exhaust per the FWF plans - tight fit with the oil sump, etc, but it does work. -The muff rotated on the pipe after it was tightened. The instructions anticipate this and say if this happens open up the holes for the through rods and clamp it down snug before tightening the rods. I did one side (of the 2 sides -there are 2 rods) at a time and of course I had to do both so I got good at taking the thing apart.
