Can anyone tell me if a 2016 fxdbc standard exhaust system will fit a 2006 fxdbi. Or up to what year after 2006 will fit. Many thanks

 

Most Dyna exhausts will fit models from 2006 through 2017. The mounts may differ, though.

 

Adding to what nevil said, also the O2 mounting bungs. Translates to different O2 sensors.

 

The 06 to 11 use the 18 mm bungs and the 12 to 17 use the 12 mm. They are in different locations so read different. I tried putting the earlier pipes on a 17 Fat Bob last year using reducing bushings and bike ran very rich. Your bike uses the 18 mm so I don't see it working unless you have bungs welded in.
