Rusted-through pipe joints, a cracked exhaust gasket or a rubber hanger that has lost its springiness easily leads to a rattling system that hangs crooked – common inspection points on the 760/780 with the V6 B280E engine (2,849 cc) in early form without the multi-link rear axle. Wear usually shows up first in the mounts and joints, not in the mufflers themselves.

This group includes the U-bolts and rubber hangers that support the system, gaskets and seal rings for the joints, plus washers, wave washers, hex nuts and plugs for assembly. The wave washers keep tension in the connections so the nuts do not vibrate loose, and new hangers help prevent the pipes from striking the underbody. Always check that the version matches your car – the early solid rear axle affects routing and suspension compared with later 760.
