okay so yesterday i got the LSJ downpipe from a friend of mine, we were lookin at it and theres only 1 bung on it, but on MY downpipe i have 2. one right after where the header bolts to the downpipe, and one under my car right after the final bend in the dp. so does that mean i do NOT have one on my header? because he has one on his LSJ header and one on his downpipe.

 

just buy a plug and plug the extra hole

 

you obviously did not read the post. MY downpipe ON MY CAR RIGHT NOW has 2 bungs. both of which are plugged. WITH an o2 sensor. his downpipe has 1 bung, leaving me with an EXTRA o2 sensor with nowhere to go

 

On the lsj there is one in the header and one in downpipe. You will need either a lsj header or add a 02 bung in the downpipe.

 

beat me too it.

 

Well Ill be getting my header soon jeremy so Ill sell you the header for cheap

 

your Bank 1 and Bank 2 O2 Sensors are both in your dp. when you switch over to the lsj dp you will need to either add a bung to the lsj dp to accommodate for both your Bank 1 and Bank 2 or you will need to pick up a late model exhaust manifold that has the Bank 1 O2 Sensor bung placed before the dp flange. the late model exhaust can be found in 2.2 trim, lsj trim or the honed/extruded gmpp exhaust manifold. none of these are a true header, fyi.

 

i wasn't aware that any of the 2.2's had a o2 bung in the manifold. the 2.4's and 2.0's all have bungs in the manifold though

 

drill a hole, weld a bung in, done. Or don't go the cheap way and buy new stuff

 

late models did. you missed the fact that i own a '06 LT. the stock exhuast mani was the splitting image of the SS exhaust mani i picked up back in '07 only with smaller ports.

 

i stand corrected then

 

I know they arent a true header just simplified it by calling it that.

 

its not a header even simplified, its a manifold but thats not really important

 

ok *******, either A. get his header too, or B. get a tune and remove ur o2 sensor. how hard was that?
