What happened to the sudden sound of the exhaust pipe of Ford Wingbeat?

I suggest you check whether the exhaust pipe link is loose or not, and check whether the three-way catalyst inside is broken, resulting in abnormal sound when you just get on the bus or accelerate rapidly. When you start the car in the morning, the vibration is relatively large, which will cause the exhaust pipe to vibrate violently. I suggest you check the spark plug and idle motor, check the oil circuit and check whether the engine carbon deposit is serious. See if there are any problems that cause the engine to shake when it is cold and the exhaust pipe to sound abnormally. I suggest you go to a regular repair shop to have a check.
