cat

did anyone notice a problem when using a downpipe and catback syatem and no cat? did it make your car run rich or lean out at all?

i just put my 3inch downpipe in and it didnt do anything but raise my boost and make my car sound like hell. Or maybe i should describe the sound...it sounds 100percent deeper and real throaty like a mild o2 dump.

it can cause a CEL becasue of the 2nd o2 sensor but some have this prob and some dont. I have NO cat and my car runs great. No cat is really the way to go if you dont have have to worry about emissions or anything

about the second o2 sensor. mine screws in way after the cat in my catback exhaust. is this normal?

well my car is made in 92 so there shouldnt be any o2 after the cat because they didnt start doing it untill 95
