hey everyone i got a question. im thinking about picking up a set of the mazzuri headers and i was woundering, if i didnt get an o2 simulator would it affect the preformance of the car at all? ive read online that sometimes your car goes into a limp mode, now is that true?? also the second o2 sensors come after the cat right?? so what if i was to just zip tie it down somewhere where it could read clean air, would that work? thanks
