Ok....I might put one on
After doing a little more research, I found a cat like the one I would need for a little over $100. I guess it seems like a small price to pay to avert a potential headache later. I do need to know one thing though.... you can order the cat with or w/o an o2 sensor bung. I would order the one with the bung if I knew my o2 sensor would fit it. If not, I could save about $30 and get the one w/o the bung and have the threads welded in.
So do all o2 sensors use the same size threads?? If not, what size is my Bosch?
