Harman tailpipe gasket

Anyone know where to get this gasket? I have ordered the part through a local dealer and I am getting tired of waiting. They order through Harman. It is hard to believe that this is a special part. It is a simple felt-like gasket. It has broken down after prior removals to clean the ventpipe. Thanks.

Maybe at an auto parts store you can get high temp gasket mat`l and cut your own?

Good idea. I just received a call from the dealer and Harman is having "issues" so he has no idea how long it would take. I imagine the gasket is over-priced to begin with. I will check the auto parts store for the mat and give it a try. I was thinking about using the high temp caulking but figured it may be a pain to remove each year.
