Running no exhaust question
Ok, everyone knows that my O2 sensor is after my cat. I have seen many people with an Si run no exhaust at the track w/a turbo kit. How does this not throw a closed loop CEL if you take the exhaust off? The O2 sensor has nothing to read.

Thanks for the bullitin from the department of the obvious. I know that, LOL. I just want to know how it doesn't trip the CEL into closed loop mode.

Re: Running no exhaust question (NYb16)
Just run the car with no 2nd O2 sensor. It's only there for emissions. It won't rob power or anything. Your CEL will be on, but who cares if you're running open exhaust anyway....
