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. The composite material is designed to swell slightly with heat and seal the connection. However, always consult your engine's service manual for specific recommendations.
