The exhaust riser gasket is a critical sealing component in your engine’s exhaust system. It creates a gas-tight seal between the exhaust manifold and riser, preventing dangerous exhaust leaks into the engine compartment and maintaining proper exhaust flow. This gasket must be replaced whenever the riser is removed for service – never reuse old exhaust gaskets as they are subjected to extreme temperatures and pressures that cause permanent compression and degradation. Always inspect risers and gaskets regularly as part of your exhaust system maintenance.
