PCM CATALYST FILTER SUPPORT

A catalyzed exhaust manifold integrates a catalytic converter directly into the exhaust manifold to reduce harmful emissions as soon as gases exit the engine cylinders. It's essential for meeting marine emission standards.
Clogging, internal damage, or reduced catalyst efficiency require replacement to maintain performance and compliance. A failing unit may cause power loss and regulatory issues.
DAM Marine supplies marine-grade catalyzed manifolds compatible with Volvo, Mercruiser, OMC, PCM… Built to resist heat, saltwater, and vibration while ensuring effective emission control.
