i have a'00 civic with a '99 ls swap. is there a way that i can run only one o2 sensor and no cat and not get a check engine light? we dont have emissions checks here so thats not a concern.i just dont want a light.
what can you possibly gain by removing the second o2 sensor?? I can understand removing the cat (for all 3 hp it's gonna give you) but most "test pipes" have the bungs for the second o2 sensor.

or use tabkolas ideas
i put a b18b1 into mt civic lx and the exhaust doesnt have the bung or the cat under the car.
