Nice DIY. How much are the SKunk2 shifters worth?
When I put my short shifter in I was lucky enough to know the owner of a wheel and tyre shop so we put it on the hoist and didn't even drop the exhaust, just worked around it.
One thing I experienced with my install was it is easy to over tighten the bolt connecting the shifter to the linkage. So I suggest you check the feel of the shifter before putting the exhaust back on and packing all your gear up.
Dual bend looks good, well done.
