O2 sensor in Cat

[BennySiR]

Kay. I put a high flow cat on my 00 SiR about a week ago now. and my check engine light keeps coming on. I got the code checked and it was the o2 sensor in the cat as I thought. Now all I can figure to make it from coming on all the time, I need to have something simulate that its there. Now what could I use for that. I've heard of lights being used for that, that have the same draw in power as an o2 sensor. but I don't want a light under my car. Any ideas anyone. Damn OBDII!!!

you can buy O2 simulators off the net... you hook them into your ecu and it puts out the same voltage as the sensor... ill look for the site and post back... i think they are like 40 bucks... then u can just run a straight pipe
