The guys at VTXexhaust.com are also doing exhausts for the VT1300's and Fury's. The question of fuel mileage always comes up and they are looking for a couple of owners (VT1300's or Fury's) to run mileage comparison between stock and their modified OEM exhaust. The offer is to send their pipes and have the owner document mileage compared to their stockers. No cost to owner. Anybody willing to help out and give it a try should email or call them.
