Where can I find a replacement muffler? (other than calling the local dealer). I have a 02 Mobius LSV and the fiberglass muffler has degraded over the years and is leaking. I have searched the internet but cannot find a similar replacement. It is a single large fiberglass piece that connects to both manifold and then down to the ports. I dont want to have to "redo" the exhaust to something different.
