It's good practice to inspect exhaust gaskets annually. In saltwater environments, they should typically be replaced whenever the manifolds and risers are serviced, usually every 3-5 years.\u003c\/p\u003e\n  \u003c\/details\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eDo I need to use any sealant with this gasket?\u003c\/summary\u003e\n    \u003cp\u003eGenerally, these gaskets are designed to be installed dry.
