750 swap

I am recently doing a 750 swap on a X2. What pipe would you recommend? I see alot about 650 west coast pipe. I am swapping out the dual keihn carbs with mikuni. If this has already been answered in a thread please post a link. Thanks

I am looking for someone in the Georgia area that can assist with installing engine in a Kawasaki x2 and all the water line routing. I am willing to pay for the help. Thanks
