Why does my Nissan Micra's engine sound louder than usual?

I've noticed that my Nissan Micra's engine has been making a louder noise than usual. It's usually a quiet car, so I'm a bit worried. Is this something I should be concerned about?

The loud engine noise could be a sign of a potential issue with your car. It's always better to be safe than sorry, so I would recommend taking it to a mechanic for a thorough checkup.

It's possible that the loud engine noise is due to a problem with the exhaust system. I would advise getting it checked out by a professional mechanic to avoid any potential safety hazards.

Sometimes a loud engine noise is simply due to wear and tear. However, I would still suggest getting it checked out by a mechanic to make sure everything is running smoothly and to avoid any costly repairs in the future.
