I recently purchased MACs with ORY. Obviously, I'll be running front sensors, but the rear ones will be deleted. However, I still have the two rear oxygen bungs to deal with.

Any idea how to cover them up on the Y-pipe ? Is there a plug that I can screw in, or do I need to weld them shut ?

Any ideas, comments would be appraciated.
Thanks

You can get a allen head plug. They are metric, I am drawing a total blank on the size?? I don't know if you can buy them separate, I got a plug when I bought a new 02 bung. Here's another idea take your old rear 02 sensor to a auto parts place, dig around in the bolt bins until you find a nut that will fit the sensor. Then you will know the size.

There is a GM part for O2 sensor delete. I think the part number is posted on this board somewhere...

Be sure to have the rear o2's tuned out of the PCM so you won't have a nice yellow SES light.
