hi,

it was suggested to me that the O2 sensor in the stock position in a
2.1 wb will not get to optimal operating temp if cat is gutted versus
intact.

this also begs the question of just well does the electrical heating
circuit in the O2 sensor works.

so what are you opinions? anyone notice any difference in O2 sensor
function in empty vs. intact cats?

cheers,

alistair
