#10570, "RE: 02 meter and cat-back question?" In response to In response to 1
The catback has a place to put the 02 sensor in it. Im not sure about the 2G but I know the Apexi 1G Downpipe replaces the stock dp AND the cat. so there isnt a place to put the High Flow cat on with it. Im pretty sure with the 2G turbos you can wire a resistor on the o2 wiring harness so you wont get a CEL. I know you can with a 2gnt, I had one on mine. Search around here. I know theres like 9878534 posts about putting the reisitor on.
