What else do I need for header install??

**1986camarojoe** · 06-02-2007, 01:49 AM

I ordered the OBX racing headers off ebay for my '99 z28, they include, Y pipe, resonators, clamps, and gaskets. I know I need bolts, but I have a few questions about the o2 sensors. Theres a bung on one of the headers and 2 on the Y pipe, I thought there was just 2?? Also do I need o2 sims and extensions or just one or the other?? I think that's it for now, thanks.

Not sure why you have 1 bung on the headers and 2 on the Y, might need to cap 1, someone correct me if I wrong. But yes you will need extensions, and unless you are gonna get it tuned with rear 02 delete, then yeah you might wanna get the sims for now to keep that pesky SES light from illum.

I was looking at extensions and it says specify flat or square connector, which will I need? also 12" or 24"? How many 02 sims will I need? anndddd will the stage 8 header bolts do the trick? Lots of stupid questions I knoww but I don't wanna order the wrong shit. Thanks

Here is examples of what you need:
http://www.ws6project.com/user_stor/...f34a3a89cb53c8 24 wouldn't hurt, better to have extra than not enough, you can always tie up the excess, and given the price won't hurt to buy the pair, that may be what that bung on the header is for is so that you only need 1 extension and you cap the coordinating one on the Y, not sure though.
http://www.ws6project.com/user_stor/...f34a3a89cb53c8 they come as a pair, cause you need 2 for your rear 02 sensors.
http://www.ws6project.com/user_stor/...f34a3a89cb53c8 so yes stage 8 will work.

and yes the plugs are square pin.
