i got my LC-1 wideband today and the instructions seem fairly straightforward but i had a question about where to put the o2 sensor. i have a catted h-pipe that has 2 free rear o2 bungs but i think they're after the cats. i shouldn't install it there, it'd give me inaccurate readings, right? if that's the case, would the crossover pipe that's in my H be ok to install a bung? then it'd be reading from the driver and passenger's side equally, no?
