There is a noticeable "hissing", "popping" or metallic knocking sound coming from the engine compartment or chassis, which can be heard at idle and significantly increases during acceleration.

Abnormal noise: There is a noticeable "hissing", "popping" or metallic knocking sound coming from the engine compartment or chassis, which can be heard at idle and significantly increases during acceleration.

Power decline: Exhaust gas leakage leads to abnormal exhaust back pressure, oxygen sensor data deviation (showing lean mixture), resulting in weak acceleration, slow acceleration, and even engine blowouts in severe cases.

Odor and smoke: Incomplete combustion of exhaust gas leaks into the engine compartment, and a pungent tail odor can be smelled. In severe cases, a faint smoke can be seen coming out of the engine compartment.

Fault light on: Due to abnormal oxygen sensor signal, the Check Engine indicator on the dashboard may light up.

Increased vibration: The gasket loses its shock absorption and buffering effect, and the body or steering wheel may experience abnormal shaking during driving, especially during rapid acceleration or throttle reduction.

Interface deformation: Check the connection of the exhaust pipe, and it may be found that the interface has unevenness or deformation marks due to high temperature impact and air leakage erosion.
