First of all, I suggest you check whether there is air leakage at the exhaust pipe interface, and you can replace the gasket to solve it.

If the exhaust pipe leaks due to corrosion, only the exhaust pipe can be replaced.

If the new car is noisy, there is no good solution. Manufacturers have different design concepts.

If you don't understand anything, you can ask me at Baichebao, and I'll give you an answer online!

If you think it's helpful, adopt it!
