The exhaust system consists of a front pipe, silencer and resonator

The downpipe is flanged (through a gasket) to the exhaust manifold with two studs with brass nuts and a clamp to a bracket rigidly fixed to the transfer case.

Exhaust system: 1 - exhaust pipe; 2 - gasket; 3 - hairpin; 4 - flange; 5 - nuts; 6, 8, 20 - ladders; 7 - bracket for fastening the receiving pipe to the transfer case; 9 - silencer; 10 - bracket; 11 - pillow; 12 - collar; 13 - resonator pipe flange; 14 - resonator; 15 - frame bracket; 16 - upper suspension spring; 17 - suspension belt; 18 - lower suspension spring; 19 - pull

The exhaust pipe is inserted into the muffler pipe and tightened with a clamp.

The silencer and resonator flanges are connected to each other by three bolts through a gasket.

The muffler is suspended from the frame on a rubber cushion, and the resonator is on a rubber belt with spring plates.

This connection provides some mobility of the exhaust system, which reduces the transmission of vibrations to the body and reduces noise in the cab.

The muffler and resonator are non-separable, they are replaced in case of failure.

Checking and maintaining the system consists in its periodic inspection and tightening loose fasteners.

The passage of gases can be judged by the increased sound of the exhaust and traces of soot on the outer surface of pipes, mufflers and their joints.
