To complete the work, you will need a viewing hole or overpass.
Execution sequence
1. We prepare the car for work (see "Preparing the car for maintenance and repair").
2. We inspect the suspension cushions of the main and additional mufflers.
Recommendation: Cushions that are cracked, torn or otherwise damaged should be replaced.
3. Violation of the tightness of the exhaust gas system is determined by traces of soot or places of gas breakthrough.
Recommendation: Gas breakthrough through flange connections can be eliminated by tightening the fasteners. The tightness of the connection between the exhaust pipe of the silencer and the catalytic converter can be restored by replacing the springs of the flange pinch bolts. If this does not help, you need to replace the metal-graphite sealing ring.
Faulty elements of the system, damaged by through corrosion, must be replaced. Restoration of elements of the exhaust system by welding gives only a short-term effect.
