there will be 2 bungs for both O2 sensors but if theres no cat the SES will come on so it needs to be deleted from the PCM

you can buy the extension but i just took extra wire and did it myself for free

X2, I always just splice in about 18" of new wire for the extension.

His rear O2 codes are already turned off in his dhp pcm, so he is good to go there.

As for the Speed Daddy headers, I have installed a few sets and the rear O2 location has never given me much trouble. There is a bung for the sensor right in front of the cat-back flange. The only issue I have had with it's location is that the big fat rubber rings that the exhaust hangs on are right there too. The one side can be hard to get on right next to the sensor.

The front O2 location is another story. Terrible location and almost always ends up so close to the floor that the sensor won't even go in without beating a dent in the floor of the car. I recommend just plugging that bung and having a new bung welded in at a better location. The top of the crossover pipe is nice, and then you don't even need an O2 extension at all.

Can you really put the o2 there? I just changed mine on my headers and it was a ***** i thought i needed a new o2 bung but finally got it after tapping it with a spark plug tap
