Note: Down stream oxygen sensor is used to make sure that Catalytic converter is working correctly. It has NOTHING do with setting engine fuel mixture. And yes, you check engine light will stay if you eliminate cat, as computer does not get information that cat is working correctly. There will be a problem, as if engine has a new code you will not know it, as light is already on. So you could end up doing damage to engine.
it will do zero damage to the engine .There are fixes available to trick the computer into thinking its got one so you dont get the check engine coming on.The engine will not get damaged at all
what u need
MIL Eliminator 's / CEL Eliminator 's / O2 Sensor Simulators
Universal Works with ALL Cars and Trucks
Have you taken your cats off and now your Check Engine Lights on. Heres that fix you've been looking for. If you're running an off-road H-pipe or X-pipe, Screw-in MIL eliminators will shut off the annoying Check engine light and improve performance. A MIL Eliminator (which is short for Malfunction Indicator Light) or CEL (check engine light) Will Limit Exhaust Gas to the rear O2 sensors when running an off road mid-pipe or some mid or x pipes with ultra high-flow cats. Also these Mil Eliminators / O2 simulators are adjustable to suit every need.
FYI : The installation is straight forward and simple. Screw the MIL eliminator in to the existing exhaust bung where the rear O2 sensor normally attaches. Then Attach the oxygen sensor to the MIL Eliminator.
Works ON ALL GAS CARS and TRUCKS 1988 to 2014. These are also Fully Adjustable if Needed.
