I do not see much advantage of pulling a high pipe closer into the bike. I believe what is really needed is a low pipe conversion that would fit below big side bags. Then you would have a great lane splitter with luggage capacity and all in nice 650 package. I even own a titanium GSXR muffler that is much smaller/lighter than stock Wee can and would do fine with a little fabrication. But my priorities lean more toward riding than to developing and fabrication.
