im thinking of doing an exhaust with the valve that opens up to make the exhaust come right out of the header (theres an ongoing thread already about this product), i plan on mounting this piece after the header and then the cat after that. Im worried as soon as a open that valve up the o2 sensor light is gunna come up. Is there any trick i can use to stop the 02 sensor from triggering? I know there was things people did to there tc's but im courious about the xbs.

Well, I know there are 02 simulators and Mil eliminators that electronically simulate a correctly working catalytic converter. I've also heard of people using a couple spark plug non-foulers to place the sensor further out of the exhaust stream. This is supposed to stop a cat inefficiency CEL from being thrown when cat-delete pipes are used.
