this may be a noob question, but heres goes!. i just got a greddy header, its doesnt have a bung for the 02 sensor. my car and motor is obd-1. so what do i do? i also will buying a hi flow cat in a few weeks

PS.i know odb-2 cars/motor have a 02 bung in the cat.
..if i have the muffler shop drilled a hole for the o2 sensor, what would happen?

 

any one?

 

1:drill hole.....2: buy bung....... 3: weld bung to where the hole is wahlla o2 sens bung ..cool

 

correct me if i am wrong. i thought the bung wAs the hole

 

The bung is what the O2 will screw into thus you first need to drill a hole in your exhaust pipe then weld the bung on.
