O2 Sensor help
I have a 2005 MN6 and looking to replace the stock exhaust with long tubes and a corsa extreme muffler system. I am in Canada and want to get rid of the cats....What do I need regarding the o2 sensors? I know the headers have a spot for them...but aren't there two downstream as well?

Just reinstall your existing front O2's into your new headers (w/ provided extentions) and unplug and remove the rear cat O2 sensors.
You will need to have the rear O2's sensors disabled during your re-tune or it will throw a code (check engine light).
