I have a Two Bros exhaust and parts for sale that I recently removed off of my fiancee's Vulcan S. Nothing is wrong with any of the parts, she just didn't like how loud the exhaust was.

Vulcan S Comp Black (p/n 005-4200199-B): $650 ($990 new)
Comp-S Silencer (p/n 005-DB-C): $60 ($88 new)
P1-X Powertip (p/n 005-P1-XK): $25 ($44 new)

I would also sell everything together for $700. I will include shipping to the lower 48 for full-price offers.
