new custom O2 sensor part ?
 

i remember seeing a new O2 band, i just cant find it. Description: u drill a hole in your exhaust and slap this band with the threaded "hole" for the O2 sensor in line w/ the drilled hole.

it's a bung hole.
no, I do know what you mean, but I don't know where to find it.


edit: actually, it turns out there is this thing called google.

i would not pay $35 for that. a weld-on bung is like $3 plus a quick weld. and you dont have to work about it leaking or the hardware getting all rusty
