yeah, thats the same page I entioned earlier. lots of great info in the manual. yes, sometimes not the greatest definition on the lettering etc, like a printed copy would have, but if you are just trying to figure out how it looks and aren't doing a numbers matching build then it's all you need.
think of it how it is, you are hanging an exhaust system. it needs to bolt up to the manifold at one end and then be supported along it's length till it exits. it needs some flexibility a little way back from the manifold connection so there is some allowance for the engine moving under torque, it is usually good to support the pipe somewhere around the muffler as this is the heaviest part of the system, and it is good to keep a distance from any frame or body parts along the way so nothing rubs under movement from engine torque or general frame/body flexing over different terrain etc.
if you were to look at a modern vehicle the system hangs on the manifold and then nottoo far away is usually a flex joint/pipe to allow a lot of flex from the engine torque, then a little back from there is a very flexible hanger system, usually rubber of some sort, that hangs the pipes and mufflers etc.
