Take drill and drill a hole in the location you are installing the O2 ( measure the correct location) weld that on and you have an O2 bung. I just did mine last week after replacing the straight pipe than ran between the cat and the tail pipes. Total cost $7 which included the welding. I do have a question what size is the cat AIM was referring to? Name of it?

I kinda disapointed with the forum a bit since so many people recommend them, but then at the same time they get a check engine light for it down the line. I didn't find out till the other day just how many there were that had this problem. Aim has found a bigger cat, but its still a thorn in my side knowing that I just dropped $140. Well the new cat costs around $130 local + I need pipe to run from the cat to the muffler since the stock pipe is very fragile. Add in the o2 bung, install, etc.. Looking at $200 minimum I fear. I should have just left the perfectly good stock cat still in the truck. Lesson Learned!

1. disconnect neg terminal on batt
2. turn key to start hold for 30 seconds
3. reconnect neg terminal on batt

basically it resets every light (cels) that are drawing power from the batt.
