i have a dy16 engine. the header has a port for the 1st oxygen sensor and the bottom sensor wont reach. i am no going to put another cat on the car and was wondering if i need the 2nd sensor? i was told it would only cause the check engine light to come on and thats about it. i was also told that a thing called a o2 simulator would cause the ecu to think that there was a cat there and no light would come on. jus tell me if i am fine with the header and first o2 sensor. and dont really need the 2nd one
