So here is a question for all the wrenches and techs out there. What is the difference in performance of the multiple exhaust designs such as 2-2 and 2-1?
Before the Cross Roads all my bikes had 4-1 exhausts. I would think that the 2-1 would be more focused on torque and midrange power with the 2-2 would be focused more on the higher rpm horsepower. The reason for my thinking is that the meeting of the two exhausts would create more back pressure and the 2-2 would be more free flowing.
What got me thinking about this is that there are now two types of full exhaust systems out there for the Cross series bikes, the Bassani 2-1 and the Freedom Performance 2-2 true duals.
What do you think? Feel free to cite tech sources and studies if you so choice.
