Re: O2 censors
Yeah, you will need those on a street driven vehicle. They are crucial for good driveability, fuel economy, and emissions.

Re: O2 censors
Not having the engine run right is a big side effect.

Re: O2 censors
i drove mine for a bit with open headers with no 02s for a few miles and IMO it ran like crap. felt like it did nothing but make a bunch of noise at wide open throttle.

Re: O2 censors
The two front, pre-cat sensors are what are used for fuel management. The two rear sensors are used to confirm the cats are functioning.
