Default Headers and side pipes

I received the headers and side pipes , oh man do they look great. I just have one question, why is there a hole in the driver side header?, is this for air to escape?

Oxygen sensor for a computer.
IF you have no computer, by a plug and fill the hole.

try this O2 sensor plug if it already has a bun

if you do not have a bun then you need to weld one on like this one:

You can probably get these at a local parts store.

Are you saying it's just a hole drilled in the tube or is there a bung welded in the pipe????? Got pictures?

He can tell you exactly what you need.

That's odd. Maybe they left it that way so the buyer can tap the threads they need??? In that case, you need a plug and a matching tap/die kit.
Or a welder and some scrap steel.

I have the same pipes from Josh. There were threads on the inside of the hole. They should be there.
