Hey guys i have a question.

I planing to make a bung at downpipe for tune but i don't know which size bolt is

fit on the bung.

Thanks Guys.

 

18 mm pitch 1.50 is the sensor thread size .

 

Take your downpipe to a muffler shop and tell them to weld on an O2 sensor bung. I did that just yesterday - handed it to them, they put it on while I waited, cost of the bung, labor, everything out the door was $20. Much easier than fooling with it yourself .
