4 o2 sensors 1990-1994
why are there 4? i want to remove my 2 cats and put in hi flow cats (aka resanators) in for some more much needed juice but will i throw a code? or check engine light due to the sensors
i dunno where it is but i saw pics of a sc400 from club lexus w/ custom test pipes made anyone know his name/link for his pics.
*i due indeed have dual cat backs but they start prob 5 or so inches behind the cats*
