Rear O2 Sensor Extension Needed?
Posted: Thu Jan 16, 2014 7:39 am
Summary of Findings: You don't need an O2 extension for any aftermarket CAT unless it is being installed further back than the original mid-pipe flange (highly unlikely). Please see posts towards end of thread for more detail.
Hi there,
I have searched and found no reference to this topic before which makes me wonder whether it is even an issue. I am planning to fit the new dump pipe probably this weekend. One of my mates had issues with the his rear O2 sensor not being long enough to reach the bung hole on his MY08 STI WRX so I got under my car for a quick look last weekend. I didn't have great access but it seemed like there was no slack in the cable and I need it to stretch an extra 30cm to get to the rear O2 bung on the new dumpster. Anyone who can advise on the slack length in this cable or having hit this issue previously would be appreciated.
Cheers,
