Mercruiser - EXHAUST MANIFOLD (18-4367)

The Sea Star Solutions Mercruiser Exhaust Manifold collects the exhaust gasses from multiple cylinders into one pipe. This exhaust manifold is a cast iron or stainless steel unit that collects engine exhaust gas from multiple cylinders and routes them to the car catalytic converter. A leak on the exhaust manifold allows exhaust gasses to escape. It is the first section of a vehicle's exhaust system, bolted directly to the engine block. It requires regular inspection to avoid catastrophic engine failure.
