Walter here are some images of the Wilburs shocks [sorry about the quality but I have just moved back into the garage after an extension and getting to the bikes is a bit hard at present - bloody mess!!!!].
The piggyback shocks would foul the genuine KLX side covers [that is why I run KX125 A4 covers - they look better too].
Sorry I can't help with the exhaust photo as I have a custom stainless pipe on the bike.
If you need more info I could take the shocks off on the weekend and show you much more detail of the frame/shock clearance and the need for the chamfer on the shock body.
Just let me know what you need.
