Marine exhaust hoses serve as flexible connectors between engine exhaust ports and fixed piping systems. They absorb engine vibrations, compensate for thermal expansion and contraction, and accommodate minor installation deviations while ensuring the exhaust passage remains sealed.

The bellows are constructed from rubber material, maintaining structural integrity when exposed to dry exhaust gases within a temperature range of 120-150°C (250-300°F). This material exhibits properties such as heat aging resistance, ensuring unobstructed airflow and long-term durability.
A distinguishing feature of early 5.7L GM-based units is a reinforced protrusion on the bellows, a design revised in subsequent production. To ensure correct fitment, a visual inspection of your current component is advised prior to purchase.
