    Important Installation Notes

    ⚠️ Professional installation strongly recommended. Marine exhaust systems require proper torque specifications and gasket alignment to prevent water intrusion and engine damage.

    ⚠️ Verify compatibility by inspecting your existing manifold and riser mating surface before purchase. Dry-joint systems feature a distinctive flat sealing surface with no water crossover passage at the manifold/riser junction.

    ⚠️ Always replace gaskets when installing new manifolds. Reusing old gaskets voids warranty and may cause premature failure.
