DYNA boarzilla VRS softail Boarzilla

[itsafatboy]

So can anyone say what the big differences are between these two pipes, other than mounting i notice the softail probably has equal length header and the dyna does not it looks more like the old propipe header,

the thing is i used a dyna boarzilla on my fatboy 117" it just fit so much better in the area by the oil tank, and mounting bracket was easy to fab, just wondering if there are other things that are night and day, it has the quite baffle haha not quite.

Always thought difference is the dyna's are set up to route around mid controls.
