John, the Touring's TORS fit the cross over box exactly the same as the original silencers same pipe diameter and round gaskets ,when I fitted my TORS I found my pipe gasket rings were still like new so I used them again and kept the ones that came with the TORS as spares ,it was a straight original off and TORS back in the same position, the "Mixer Box" on the Touring has a mounting bracket on it I don't know if the roadsters and Classics have the same mounting , also my Touring has ABS I don't know if that make any difference
Cheers Ken
