The exhaust system is rigidly connected to the exhaust manifold and through the holder - to the gearbox. On the bottom of the car, it is freely suspended on rubber loops.
Check the retaining rubber bands for breaks, cracks or other damage, replace if necessary.
Check the threaded fasteners on the exhaust manifold and on the holder on the gearbox for tightness, but do not pull them hard.
With the engine running, plug the outlet of the exhaust pipe with a rag. The engine should stall after a short time.
If you hear a hiss and the engine continues to run, you need to look for leaks at the site of the noise.
A dull exhaust sound and popping sound when coasting usually indicates that the exhaust stroke has rusted.
Mufflers are initially damaged by rust at the seams. If they need to be left for some more time, it is necessary to make a detonation test in this place with a screwdriver.
