Long tubes are "fun" to install, there is no doubt about it. When you do the install have a couple friends over. One to help with the jack while you wiggle, and the other behind the front wheel looking from the back to help guide you. This isn't necessary, but it helped me out a lot.
Buy new O2 sensors before the install unless they are new. My friend said he just went to Auto Zone and they had an O2 sensor for his 5.0 with longer wires. May be a good idea to check into it.
