wus up everyone my friend has a 97 del sol si he is havin a problem with the o2 sensors and needs to pass emissions.the old oem exhaust manifold was cracked in alot of places and he was having a hard time finding another oem manifold and cat under 200 with out instalation included so he jus bought aftermarker headers and downpipe and an universal legit catalytic convertor.in order to install it the o2 sensors had to be extended and shops were tellin me a lot of diferent things like if u extend the sensor the light will come on and that the sensor must be behind the cat or it wont work either.but ive heard of plenty of people doin this with no prob is this true or does it matter at all?can some one help us out with this ive searched but ive only gotten bits and pieces but not enough to figure this out.
