OBX Headers?
 

I just got some they went in nice and they look nice. But the O2 sensor will not fit into the weld that is on the pipe.

has anyone else ran into this problem? what did you do?

thanks for any help

Drill...., tap and dye.

the o2 sensor needs to be closer to the header (i have mine where it y's). if you dont you will get bad gas mileage, i've been there

thanks
 

thanks for the help. will any exhaust shop do the welding for me?

Probably. I bet alot uf us have an exhaust guy we all trust.

You can call around and find out who installs Cat converters. They will be able to weld you in a new BUNG (threaded round 'nut' thing) that the O2 screws into.

You can plug the old BUNG with a bolt (what I would do), or have them weld it closed.
