Arg! The guy that put those in that spot needs to be beaten! Trying to get the one off the drivers side is making me crazy. What size wrench do I need for it? apparently none of the wrenches I have are big enough except one of those adjustable ones but it like to loosen up just enough that Im afraid Im going to round off the nut. And I cant get my hand up there to unclip it either. ARG! how did you guys with aftermarket mids pipes do it? I know the thing cant be too rusted on since they had to have removed the pipe when I had the tranny rebuilt. This was sposed to be easy .... now everything else but the drivers side 02 is off and im stuck.
