Default secondary o2 question (not miata)

Hey guys... my daily just came up with a check engine light for secondary o2.

i went under the car and took a peek and diagnosed it to be a faulty o2.

When i removed the o2, i noticed it was rubbing (hard) on the shifter linkage (its fwd)

being that i dont want to have to replace the o2 again being that it was likely engine vibrations through the shift linkage, i want to weld a new o2 bung on there which is no problem.

The current o2 bung is mid-cat on this aftermarket unit. do i have to weld the new bung mid-cat or can i install it in the inch or 2 of pipe between the cat and the catback 3 bolt flange such that it operates properly and doesnt throw a code?


ps, car is a 2000 honda civic sir with factory b16
