cat removal- 92 lt1
ok i have a cloged cat. i dont have to worry about emissions. so is there any reason why i would want to keep cats on? i think i want straight pipes in their place. i have shorty headers. will i get any codes thrown by doing this? how much should i be looking at to do it?
thx

"Cat" removal
I just finished putting long-tube headers on our '96 coupe. I removed both cats . I installed "O2 sims" for the sensors behind the cats and reinstalled the ones in front of the cats(into the headers). I have had NO problems at all. I don't know if your "OBD" system is the same as mine.

that's affirmative, there are no o2 sensors after the cats on the 92, just one o2 sensor on each side in the manifolds that picks up on how rich the car is running and adjusts things accordingly.
