I have seen this question for other v-6's, but how do I get to the 2 rear plugs nearest the passenger side of the car? Can I get to them by taking off the catalytic converter and then reaching up from below? Also, if this is the right way to get to them can I undo just the 4 bolts that connect the converter to the exhaust manifold and move it out of the way or is there more that needs to be disconnected? Thanks for any help!
