What is recommended regarding engine exhaust systems on a PWC?

Keeping the engine exhaust systems standard on a personal watercraft (PWC) is important for several reasons. Standard exhaust systems are designed to comply with regulations regarding noise levels, which helps to mitigate the impact of boating activities on wildlife and natural environments. Excessive noise not only affects marine life but can also lead to disturbances in the surrounding communities.

Furthermore, keeping the exhaust system standard ensures that the engine runs efficiently within the manufacturer's designed parameters. Modifying the exhaust could lead to performance issues, increased emissions, and potential damage to the engine. Maintaining the designed exhaust helps reduce issues related to noise levels while ensuring the PWC operates safely and effectively.

In contrast, modifying the exhaust for increased speed could compromise sound regulations and safety, while frequently changing it or using aftermarket parts may not provide the reliability or management of emissions and noise that a standard system offers. Hence, standard exhaust systems are recommended to promote responsible and enjoyable boating experiences.
