shouldn't change at all..... anyway isn't the O2 sensor Pre cat anyhow, even if it is in the first section of that cat, it is still before the platinum.

also curious though if someone know differently.

i guess it would depend on type of cat.. but i don't think location really matters in order for sensor to function
