After an inspection (or replacement), it's equally important to replace the gaskets. Sierra Marine offers gaskets in a variety of configurations for direct-fitment on most popular engine make applications. Sierra Marine exhaust manifold gaskets are designed to perfectly match the exhaust ports for your engine.
