What is a legal requirement regarding mufflers on cars?

Having a muffler in good working condition is a legal requirement because it plays a crucial role in controlling the noise produced by a vehicle's engine. Mufflers are designed to reduce engine noise to acceptable levels, which helps maintain a peaceful environment and comply with local noise ordinances. Additionally, a functioning muffler is important for the overall performance of the vehicle and its emissions system, as it can also help reduce harmful pollutants released into the atmosphere.

Some options suggest that vehicles could be exempt from having a muffler or propose alternatives, such as bypass systems or special regulations only for electric vehicles, but such allowances do not align with standard legal vehicle requirements. All motor vehicles, regardless of type, generally need to meet noise control standards, thus making the requirement for a properly functioning muffler universally applicable.
