You are a retard, plain and simple. While youre at it, why dont you just take the MAF off? I mean if youre gonna run around without your o2's so your car doesnt know whats going on fuel wise, you might as well run without a MAF so your car will really not know whats going on. I mean dude, you took out the only way your car knows how to adjust a/f ratios and thats just retarded. Youre probably having drivability issues and such and your probably getting horrible fuel mileage compared to what you'd be getting with the front o2's in and a proper tune done to adjust for the o/r pipe and turning off the rear o2's. Nobody cares if youre rear o2's arent in cus they only tell your computer that your cats are working. turning them off with the tuner will just fake your computer into thinking that they are perfect. But thats just plain retarded to run your car without an o2 sensors at all.
