I removed my stock exhaust to put on an Arrow slip on a few months back and there was a metallic gasket that had to be removed to install the slip on muffler. Now that I am returning the stock muffler I need another gasket for it to fit properly. Does anyone know where to find this gasket? it is almost like a metallic gasket wrap that goes around the pipe where the muffler claps to it. Any help would be appreciated!
