She's a 2000 Vstar 650, lots of changes (Harley springer seat, ape bars, LED brake lights, headlight is custom, removed fog lights and turn signals. Its got the foot panels instead of pegs. Some sort of custom pipes that are flexible, I dont much care for those, but thats about it.) Got her for KBB value of 2900, with not quite 30,000 miles on it. She sounds great, but I cant figure out what the hell kind of exhaust is on her. Im open to suggestions on where the hell/how I can put the tag on it as well. Thanks people!  

That's probably a hand made exhaust for that bike, flex pipe welded or even just clamped to cutoff stubs of oem exhaust.

I've seen car and truck exhaust systems repaired with flex pipe, but that was 30 or 40 years ago. I wouldn't expect it to last long unless the bike is running really rich, to keep the exhaust gasses relatively cool. I didn't know that exhaust flex pipe was still available :-)

For the tag bracket, I've seen brackets in catalogs, that mount on the axle nut or fender strut, with the tag mounted vertically instead of horizontally. It would probably be fairly easy to modify a tag bracket to use the tail light mounting bolts.
