rough diagram from the side - camps/hangers look more like the car parts than the few truck parts.

If you are referring to a 216 truck exhaust system, there is an exhaust pipe a muffler and a tailpipe.

There very few clamps/hangers.
- exhaust pipe attaches to the exhaust manifold
- donut between the exhaust pipe and exhaust manifold
- two mounting studs in the exhaust manifold (and two nuts - long brass nuts are nice)

clamp the exhaust pipe to the IN side of the muffler
- forward/front clamp
- muffler
- rear clamp
- clamp the tail pipe to the OUT side of the muffler

- muffler hanger strap - hanger it attached to the frame
- another illustration of muffler hanger
- muffler bracket that is attached to the frame - the muffler strap is attached to this

The tailpipe, as posted above, has a hump that goes above the real axle housing.

There is heat-shield plate that attaches to the underside of the bed, above the top of the hump in the tailpipe

- rear tailpipe hanger - goes around the tailpipe and attaches to the frame

Especially note the advice/instructions in the last paragraph on this page.
