To tap or not to tap?

[Maengelito]

Ah yeah, if you guys have any other suggestions I haven't thought of yet, by all means let me know! So Maeng you basically just used a nut that fit the size of the sensor as a new bung? Did the guy weld it on while the exhaust was still on the car?

yeah, i might even have an extra nut lying around because i bought a couple incase something went wrong. i'll have to sort through my box of loose nuts and bolts. the guy welded it on the exhaust with the car on a lift and exhaust still attached. i'm sure you could go to any muffler shop and they'd do it for you. in fact, i bet they have bungs there that they could weld on as well.
