Seems as though the underseat exhaust are mainly to support the need for Euro V Bullsh*t. Larger cat on the bottom and two cans up top to meet more stringent emissions and sound regulations. Trellis may just be there to test new exhaust system although I truly hope they go back to that style frame. Some places mentioned the use of the new Mutli 950 motor for the DVT stuff but I don't know much about that motor. Hope it looks cool, hope its awesome, if the power is up there, would make a nice hyperstrada.
