I got a new set of Vance and Hines Big Shots for my FXDWG for Christmas and got them put on today. It took a little over 3 hours to do it by myself. A helper would have speeded up the install end of it. Took it out for a short 15 mile ride. It was 35 degree's tops today. That's all the cold I could stand. The new pipes sound awesome, even to my old half deaf hearing.
