If you have occasion to remove your exhaust, you may find your gasket all squished out of shape. Maybe when you pull the pipe, the gasket rolls away under the bench. If you notice black carbon around the port, it’s time to get sealing from a new gasket. I see eBay sellers offering these gaskets for about my price but then they add $5.95 for shipping.
