O2 sensors

(1990 Ford Bronco)
in Baldwin, WI on April 29, 2011
Can I install dual exhaust on my bronco and remove the O2 sensor? Headers, pipes. I only use the bronco on the trails and 4 wheeling?

Popular Answer
The O2 sensor trims fuel mixture, removing them would set a Check Engine Light, headers may pick up power but you would loose proper fuel trim, better to keep O2 sensors see if any one makes headers that accept O2 sensors and or put a more free flowing exhaust on the truck from the sensors back.
