I purchased this exhaust and had it installed at Doerfler's on a 2016 Dyna.  I really liked the sound, but replaced it so I could put the rear pegs back on.  I had them on for about a 1 1/2 years.  It will fit bikes other than the Dyna. 

You can read about this system and see it on a bike at Revzilla.  This is the link.

On the Dyna, the rear pegs had to be removed and it is a challenge to check the oil.  The oil can be checked but you have to work it around and hold your mouth just right. 

As I was taking the photos, I noticed there is a crack where the bracket is welded to the pipes, so it will need to be welded.  I tried to take a close-up photo of the crack.
