If it's leaking, it will only get worse. If you can hear a leak, then replace the gasket for that pipe. I think you will have to get a set of six, but they're easy to do. Be advised, soak the nuts and studs with penetrating oil be fore trying to remove them. On my 300E, I removed the studs and replaced them with stainless steel metric cap screws. That way, if you ever have to do anything with the head, the exhaust studs will not be in the way, and they won't corrode..

No matter what you fix, there will always be something else to fix..
"Warranty" is just another way of postponing the inevitable.
