Sounds like a new muffler is in order, obviously. I would suggest figuring out a way to secure the muffler to the frame closer to the exhaust exit. This will take the load off the header and help it resist all the crazy vibrations. If you do a search, you should find some ideas on how to accomplish it. I, personally run the SBP expansion chamber, so I haven't done it myself. As for the plug wire, a NGK motorcycle wire should do just fine. I picked mine up from a local moped dealer. Any motorcycle shop should be able to help you on that one.

Also, the header bolts can be removed and replaced with some Grade 5 or Grade 8 studs and nuts/lock washers.
