I was looking at them here: http://cgi.ebay.com/ebaymotors/OBX-H...QQcmdZViewItem
And it looks like they have cats on them. I see actually 3 O2 bungs for some reason, but definitely a very clear one on each side of the cat. Are those fake cats? I'm buying them if not. I guess I can gut them if they ARE cats.

Those are fake cats. There was a thread with some pictures showing the inside was empty. Post #28 https://www.performancetrucks.net/fo...ht=obx+headers

Thanks man. If they weren't fake, they were going to be once I got them. LOL!
Oh, are O2 extensions required for long tubes on these trucks? I know on the GTO and F-body they are.

No 02 extensions but you will need some plugs for the rear two 02 bungs as they are not needed.You will like them when you get them they are verry good quality IMO.If I was to do it over I would buy them again!

Nice. Advance Auto has the bung plugs. They usually don't know it, but they have them.

Yup, the plugs are an 18mm X 1.5 thread. I have found replacement oil drain plugs can share the same thread.

I appreciate all the help! I am going to look into the OBX a little more, before I make a choice

The pacesetter and the OBX headers are both nice I looked at both of them when I was looking at headers. If you remove the rear O2s you will need to get sims or have them turned off in your tune

Only thing that sucks..........

I guess "bung plugs" sounds pretty gross. I never even thought that when I typed it in. And I would get them tuned out and forget them forever.


Care to clue us in? I don't see anything that sucks there, but I'm probably missing it.
