Bill, I'm not sure I follow you. The oil line is still in the same place it's always been with the old exhaust, just slightly bent to clear the previously non-existent passengers side exhaust outlet. So there really aren't any problems there that weren't there before in regards to exhaust heat transfer into the oil line.

Also, this is the scavenge line that is pumping oil back to the tank, where it can sit in the tank and cool off.

But you're probably just pondering an "ideal" set-up. In which case, I agree. The back-dated oil lines are ideal, but the question for most people is surely "is it worth the extra money?"
