As DoubleF suggested, I would just put something on the wall to protect it from the discoloration.
That said, I just wanted to chime in before you do something you shouldn't: DON'T put a 90° elbow facing down on the exhaust at any point. Your furnace is a condensing model that very deliberately tries to get water to condense out of the flue gases and fall back into the furnace; the flue pipe needs to be sloped back to the furnace. If you put a 90 pointing down on it you'll likely just cause issues with condensate pooling and icing up.
You can
usually terminate the exhaust with a 45° elbow, a tee fitting, or a horizontal extension to get it away from the house. Your furnace's installation manual should have this info in it. The horizontal extension would solve your problem, but the permissible length is usually limited (I typically see max 12" extension for a 2"Ø pipe, or 20" for 3"Ø; again, this should be in the installation manual).
