If your running a USDM ecu, then replace the bung on the Jpipe with fatty O2 sensor and you should be good .

Because if i can run a skinny 02 on a usdm ecu it will save me a trip to the muffler shop to have a fat bung weld to it but if I have to change the bung on the j pipe then I will

nothing needs to be welded, it screws into the o2 housing

Personally, I wouldn't mix o2 sensors. Use the one ECU requires or you will be getting more headaches that does not worth it. Skinny and fatty are different internally so they behaive different too.

I had a fatty rear O2 sensor brand new on my stock 98 ECU and when placed JWT 97 ECU had to replaced it with a new skinny as the other did not worked properly.

Im sorry I have't given you guys all the info on the car, it needs to be welded in because the J pipe is not the factory one hell it does't have the stock turbo I did some research and found out that the turbo is from a izusu truck, so im trying to make this run ok because something tells me the previous owner did not really care for her and now im thinking i got ripp off but i love B13 's
