1. Check the condition of the exhaust system from the engine to the end section. Perform the check on a cold engine, at least 3 hours after the trip. To check, it is best to raise the car to provide unhindered access to all parts of the system.
2. Check the exhaust pipes and connections for signs of exhaust gas leakage, severe corrosion and mechanical damage. Check that all brackets and exhaust pipe supports are secure and intact (see photo).
3. Check the condition of the bottom, the presence of through lesions and open seams through which gases can enter the passenger compartment.
4. Shake pipes with mufflers. If the pipes and mufflers come into contact with the suspension parts or the underbody, replace the fasteners, or if possible, separate the pipes and rotate them relative to each other to ensure sufficient distance from other parts.
