So...I've been having a problem with my o2 sensors not heating up properly. The front sensors are in my LT header collectors, and the back sensors are about a foot behind that. I came up with the idea to put high flow converters between the 2 sensors. In theory, it should help the sensors to heat up properly. If all else fails, I at least won't be smoking when I go WOT. Is there anything that I am missing? Appreciate the time.

Thats the way GM did it.

If i dont have cats but i put the two rear o2 sensors in, will that turn off my ses light?

i dont think that will turn your ses light off. i have no cats and i still have the sensors on mine and my light is still on too.

I went to CAM and got the car tuned, he turned the sensor off haha
