Drill hole after cat.
Weld bung onto hole.
Wires may need to be extended for 2nd O2 sensor.
Attach O2 sensor in new bung.
TA DA!!

^^^ He's right, there is nothing else to do... the two sensors are used to monitor the condition of the cat to ensure efficiency. No cat = MIL

cant u trick the system and wire both sensors to one.

imported_gatherer

won't that cause the ecu to throw a code because the air before the cat sensor and the air after the cat at the next o2 sensor would seem to be the same (since the signal is coming from the same source)

well in my header i have two o2 sensors..
both are in header
i dont have one in cat.
so now what do i do

imported_gatherer

well if the header grew another hole (you said it had one) then it's time to just use those and see what happens can't hurt can it?

sikcrx80

ok
well my DC header has only one hole and my oem header has two holes....
so this is where i am lost... i dont know how to wire it up.etc...

imported_gatherer

your OEM header is it one of those that has the cat before the down pipe?

sikcrx80

well my cat is by my shifter.. i hope that in answers ur question.
i was told i could wire the two together and it would work but it would run rich is that true..
i emailed DC Sports and one of the guys there told me that.
So ???
