I have a 2000 civic si. Right now i have no cat at all on my car. its straigt piping all the way back to an n1 muffler. Since there is no cat on there, i had to just zip tie the o2 sensor up to the bottom of the car... lol.. bear with me now. I am getting the cel light for it and I was wondering if anyone had an old post on how or knew where I could get instructions on making the ecu think its still there. It sounds confusing but I think what I'm tryin to say is how do I get the cel to go away and also make my car run like there is an o2 sensor there. I remember something like buying some resistors or something from radio shack and soldering them on the end of the wires ???
Thanks a million,

Buy a free flowing cat and avoid the possible $3000.00 fine.

 

We don't have smog test in FL and the cops don't really care about how loud your car sounds.
