I just took out my dc header and i'm about to put in my jg header with modded collector. i had a o2 bung welded on the jgheader, but now there is no o2 bung on the dc header. so i'm have a bung in the jg header, without having any sensors put in the jg header. I'm a newb, help????? Do i just get the o2 bung on the jg header weld in or just leave it open? Please help

 

how come you dont have a 02 sensor ? if you dont use a 02 sensor just go back to where ever you got the bung welded and see if they have a piece that can screw in there to fill up the hole .

 

thanks
