How far back in the downpipe do I need to place the bung for the O2 sensor? I assume that right after the turbo is too Close.


Closer to the turbo is better, a couple bends back if you think it may spit the turbine :). Wrap the downpipe back to the O2 sensor to conserve heat.


So if I keep egt on the south side of 1600 I should be ok? :)
