hi there thought i might look for some help as supraforums basically doesnt have the search option and all the old posts have been deleted.
i have a jdm 97 supra. and basically ive noticed that there is a 3rd o2 sensor that is on the end of the factory header. how do i remove this and where does this go? there is not a 3rd bung on the mvp header to accomodate this.
any ideas?

 

well the 2j's that i have seen or delt with only have 2 o2 sensors... Not to sure what the 3rd one is for. If this place doesn't help. You can try ClubNa-t.com. Though they are a Non-turbo to Turbo club. They might be able to send help your way.

 

my 97 had a 3rd o2 as well just get a bung and put it in the exhaust right after the header

 

The 3 rd oxygen sensor is a catalyst monitor for OBD2 cars.
If your running catless & you install it in the exhaust you will
get a 'check engine light' (MIL) ON for cat efficency below
limit. You may need to delete it & run a o2 simulator in its place.

If you are running a cat, it goes AFTER it.
