O2 hole/plug
Hey the header I bought had a slot for the O2 sensor so we installed it into there, and I have a O2 hole in my Cat as well, I was wondering if anyone knew what size bolt/plug I should get to plug the hole, cuz the exhaust is a bit loud w/ no plug in the Cat...

Secondary O2 Sensor thread size
Could anyone tell me what the thread size of the secondary o2 sensor is or where I could find out? Ive been trying to find out for a while so I can get it drilled in my cat replacement pipe by the manufacturer. Ive got a JDM Prelude 2.2 Si Vtec (93) H22A
