When performing any work on the exhaust system, the machine must be absolutely secured against movement in a raised position, so that it cannot tip over when jolted, even if the pipes are rotated or pulled.
If any threaded connection cannot be disconnected during disassembly, it should be torn off by twisting. New screws and nuts are installed during assembly.
Just in case, the retaining rings are also replaced.
Exhaust pipe connections are best separated when heated. The workshop uses a welding torch or blowtorch for this purpose.
If the pipes are cold, a rust-dissolving agent is used to disconnect them.
The pipes are separated using strong rotational movements or by hitting them with a hammer.
If these methods do not help, then the pipe connections of the damaged muffler are sawn at a place that is 10 cm further from the joint.
The remainder of the pipe is cut with a hacksaw in the longitudinal direction and removed with a powerful screwdriver.
Threaded connections of the exhaust system are easier to separate if the threads were lubricated with graphite paste during assembly.
The areas between the joints can be lubricated with graphite paste, which will make disassembly easier later.
When assembling, pay attention to the connection of all parts of the system (there should be no tension).
Temporarily connect the parts together, install fixing brackets on the tubes, and adjust.
Hang the exhaust system with its retaining rings to the body.
Rubber holders must experience uniform, tensile forces.
There must be sufficient distance from the exhaust system to the body. By shifting or turning the pipes and mufflers, arrange them longitudinally so that they are at the same distance from the body. Between the buffer (not all models) there must be a certain gap between the rear muffler and the bottom of the trunk.
Only after the exhaust system has been adjusted can the threaded connections be finally tightened.
If during a test drive it is discovered that the exhaust system is still rattling somewhere, it is necessary to disconnect the clamps again (caution: pipes may be hot!) and recheck the installation of the exhaust system.
Note: If the exhaust system was installed with too much tension, extraneous noise will occur. In addition, internal stresses can contribute to cracks. Small leaks in one of the connections of the new exhaust system can be eliminated by using a sealant.
