why two pipes?

yes your right water warrior 2 valves flow more than 1 but no need for two separate exhaust ports. my fzr is a 5 valves and its got one pipe per cylinder so if there was some sort of advantage to this you would think more manufactures would be doing it to.clearing the frame seems to be number 1 in my book, along wiht suzuki might have been experimenting with the concept but couldnt justify the extra cost of all the extra stuff that goes with 2 seprate ports. just a thought
on the TU with its 2 valve head. i wanna say they did this for a torque increase. its true a four valve head will flow better than a 2 valve, but depending on valve lift and some other factors like RPM, more usable torque is probably the end result for the TU. not to mention FI which would add a ton of midrange punch to the mill. i bet you that bike will run circles around this one
