Dave, that would be called a 4 into 2. 4 headers leaving the engine, ending in two pipes total (one muffler on each side).
My Sprint ST is a 2001. Along with my 750Four, it is my regular ride. They are radically different from each other. I can't say I like one better than the other; but in some ways I prefer my old bike. If I had to have only one, and could figure out how to have nice unobtrusive lockable hard bags on the Honda, I'd be set. 'Course, power response, handling, braking, mpg are all better on the Triumph...
I still have to set it up so I can sit up just a little more. My short arms have me leaning forward more than I like.
CT to Canada will be a great ride! Are you going to the Maritimes, or inland? Up through Maine, or VT?
