lost arrow exhaust o2 plug

Hey guys,

Does anyone know what the replacement bolt size for the o2 plug is? This is for the arrow exhaust slipon; seems like it vibrated off and now making a real raspy sound. I heard 18.5 but I'm not too sure, anyone know? Thank you!

Was it plugged into anything or just sitting in the exhaust?
it's plugged right before the can. I have no use for an o2 sensor; hence I need the plug. Wondering if it's a 18 or a 12..
I'm wondering if you found the solution, is it an 18 or 12?
