The problem will be obvious to some folks:
But for those whom the picture doesn't explain it: the shock is too long, and the rear axle bolt will hit on the muffler constantly if I were to force installation of the taller shock!
So... Since we should all know by now that: You can't always have what you want...
It seems I have several options:
1. Cut a few inches out of my header and attempt to gas weld (braze) it back together into a length that will allow the shorter exhaust system to clear the longer shock. (Hot, sooty exhaust may come out on something /somewhere I don't want it).
2. Take the decent sounding short Dyna/Sporty muffler off my chopper and put it on the road bike. As the Supertrapp is just too long and ugly to put on the chopper: I'd then have and excuse to put the embarrassingly super LOUD turnout muffler on the Chopper.
But the Supertrapp has got to go on one of the three bikes; because though it is ugly, it is the coolest sounding, not obscene loud, muffler I've heard!
Decisions, decisions... Sometimes I hate having too many options!
