Thanks for the input guys, as I can see the OBX doesn't have such a bad reputation.

Paul, you think you would still be able to build that custom bracket if I buy an OBX?

Racing parts depot. They have a eBay store and at one point had their own website. The website price was cheaper than the eBay price.

I cannot find their website but their eBay store is up.

Paul your dip stick header bracket works and fits perfectly on my OBX headers.

I'll second that.

Re: Which headers should I buy, bang for the buck?

I definately need to relocate my o2 sensor, hence I needed the extension.

I relocated mine by "splicing in" a section of (high temp) wire and wrapping it with a heat shield strip before tucking and running it under the existing heat shields.

BTW, for those that wish easy access to the O2 sensors for either general maintenance, OR to remove them temporarily to insert that wide-band O2s when WOT testing on the dyno, may I suggest installing the bungs on the side of the header collectors so that the O2 sensor juts out horizontally toward the rocker panel. That way you'll have access to them w/o even having to jack the car up to get to them.

I welded mine at approx 85º from the top of the collector so they angle above the frame rail out of the way. (I got my Z airborne by about 2-3' - at a 1/2 mile WANNAGOFAST event - before coming down on soft earth and the O2s didn't even gather grass! I think they're OK located there. BUT, you're welcome to duplicate the test to see for yourself...:p)

Re: Which headers should I buy, bang for the buck?

Thanks for everything guys. Paul, I'll let you know when I buy some headers! Thanks a lot you're really helpful...

Re: Which headers should I buy, bang for the buck?

I read somewhere in this forum, I think, that a particular O2 sensor part number comes with a longer lead. I ordered them, and didn't need an extension (but that may be because the OBX headers have the bung closer to the stock location?).

Re: Which headers should I buy, bang for the buck?

I purchased SW headers and hope to have them installed shortly. They came with a long lead for one O2 sensor. Will post up photos of the install and video of before and after sound. Now I have Corsa with stock cats. The SW headers have the SW cats.

They are comparable to SW without the member discount.

Re: Which headers should I buy, bang for the buck?

Guys,

Where do I get an O2 sensor extension? Will I only need one? Driver side or passenger side? And while I'm there, should I replace them? My '91 has 28,000 miles. And is it an emergency to get a chip from Haibeck once my headers are installed?

Thanks!

Re: Which headers should I buy, bang for the buck?

Passenger side only.
My mechanic made one with weather pac connectors.
Drive lightly until you get the chip retuned, the car will run lean.
