Received & installed the exhaust. As previously mentioned and I thought there was another post detailing why the supplied center stand bracket doesn't work for the 2014 CB1100 (Std. model, not sure about the others).
The 2014 center stand return springs were relocated from the side to the center.
Here's the stand out with Yoshimura bracket, and return springs. The springs will hit the stand when it retracts. Others have cut the bracket in two pieces leaving enough room for the springs. Not sure how that will hold up over time.
Here's a shot without the springs, loosely on the bike
At this point I'm leaving the center stand off, and will likely add this to the winter project list. Initial thoughts include some sort of stop/bracket that utilizes the stock center exhaust support (not used for the Yoshimura system).
Really like the exhaust

. Not loud, but has the look & throaty sound I was after.
