How does a wet exhaust system differ from a dry exhaust system?

A wet exhaust system is characterized by the mixing of water with exhaust gases, which is a key feature that differentiates it from a dry exhaust system. In this configuration, water is introduced into the exhaust system, where it helps to cool and reduce the temperature of the exhaust gases, enabling efficient operation and reducing emissions. This mixing process also helps in muffling sound, enhancing the effectiveness of the exhaust system.

In contrast, a dry exhaust system typically does not incorporate water into the exhaust gases. Instead, it relies on materials and design to manage temperature and noise. There are also systems that may use a heat exchanger or rely purely on air to dissipate heat, which distinguishes them from the wet exhaust setup.

Wet exhaust systems are common in marine applications because they manage the high temperatures associated with engine exhaust while protecting the integrity of the exhaust components. This feature is crucial for the longevity and performance of the system in a marine environment.
