I do not know about the snorkel, but I do know that the ARB bumpers can fit the 2008-2011 LX. I would think it would fit the 2013, but not verified.
The shop that did this is called Baer Trax and is located in Texas. They said it took about 40 hours of labor as some adjustments have to be made to fit the LX. He did not go into details though.
