Does anyone know if the 06' RK Custom has the narrow or wideband o2 sensor or any at all.From what I understand if it does it can make it hard or impossible to modify so I would then lean towards an 05'.

Only the Dyna's have the o2 sensors. The 06 touring bikes do have Catalytic mufflers, while the 05's do not.

No big deal...I love my 06 Ultra:yes:

Thanx Bedemonster...How do the cats effect the install of a V&H exhaust?

The CAT's are in the right side muffler only on the baggers and are very restrictive. Installing V&H slip-on mufflers will increase your performance when compared to stock & cool down your engine.
