Noticed that exhaust setup when it was posted on the HD website a couple of days ago. Did you also notice, however, that in its fitment description it reads something like "fits 05 EFI bikes (except CVO)."
That "except CVO" part really stymied me as for the life of me I can't think of what would be different. Obviously nothing physically to keep the pipes from bolting on so it must be something different in the onboard electronics to control (or not to control) the added electronics and valve that are part of the new system. Or maybe it's just that the added electronics that are part of the new system aren't calibrated to match the higher displacement engine? For whatever reason though, HD is saying the pipe system won't work with our bikes.
