OBX Headers?

[Aurora40]

You could add cats, just like some people do with SW headers.

Great price - 'bout the deal I got on the group buy that Dave arranged a year and some ago on the SW headers. (Thanks again, Dave!)

Smooth, gradual transistions mean a lot, when it comes to swaging pulses into tight places, and the closer to the source (engine), the more important it is for "impedance matching" (if I may borrow a term from electronics). Far as that goes, and without anything in the way of real data to go on (so take it for what it is worth), I like the SW's collector much better than the the pictured OBXs (or Watson headers too, for that matter!). So, like little "Mikey" in the cerial commercial...

"I'm not gonna try it...YOU try it!"

Well, I hope someone does try them and tells us what they think.

Did some more searching, and it does seem that they are made in China.

I don't know about the domestic world, but in the import world obx is considered by many to be the junk of the junk. I would avoid them like the plague if you value good fitment, quality welds and longevity in a product. personally putting headers on the zr-1 is a project that I would only want to do once

Here's a little something to ponder on.

SW has install/fitment issues also.
So if i had a choice i would rather get screwed for $400 then $1300.
I'm a cheap screw.

Those who have SW headers on there Z's go look under your Z one header hangs lower 1"-2" ,this was mentioned to them.

Jeals are the best i have seen & worked with,of course they were made in Germany,those Germans can build some sh!t.

Do a search on LT5 SW headers.

I'm not a hater what i do hate is a monopoly on LT5 parts.
As you all know monopoly is against the law in the USA.

While I appreciate competitive products as much as the next guy, you are assuming there is infact a product worth comparing.Go to supraforums, and look up obx headers, and read the posts. Not only are their headers made from far inferior materials, the workmanship seems to be non -existent, and welds are along the lines of a third graders abilities. Headers made by obx routinely rust out, crack, and require much work to make them seal properly, as well as much effort to reinforce, as well as brace..

Sometimes paying more for a quality piece upfront is infact being frugal, but I guess it is all a mater of how valuable your time is worth to you when you basically have to refabricate a part.

the prices we pay for headers are insane, shame these seem to not be up to par

It seems much of the older obx header crap on sf has been archived, or deleted. I could only find this one

Did you install this OBX header yet? Did it go OK??
I attempted to do mine yesterday and had a LOT of trouble. First the front part of the flange had to be ground A LOT to clear the head just under the distributor.Then the downpipe angle was ALL WRONG! (couldnt even attach it without hitting the transmission crossmember) and it therefore needed a bunch of additional bending (we had no choice but to just do heated bends) THEN after extending the O2 sensor wire 4' so it would reach we found the O2 sensor hole in the header was WAY TOO SMALL for the sensor! So we drilled it out about 3/16" larger so the sensor would at least fit in BUT THEN found the O2 flange mounting bolt/stud holes were not the correct spacing. THEN while using a die grinder to oblong the holes so we could mount the sensor, the flange broke completely off! - no doubt due to the fact that we had made the wall TOO THIN after drilling it to accept the sensor.
We ended up having to weld up the OBX sensor flange (what was left of it) and added a thread-in bung further upstream into the collector (the threaded style was all they had at the muffler shop) and used a GM thread-in 1-wire sensor. (not all that bad anyways as it will now work with the LSU4 WBO2 too)
But because the downpipe alignment was all screwed up , our test pipe and catback exhaust was now all out-of-whack and we had to bend it a bit and cut and reweld a couple of the hangers to make it fit.

All in all the WORST "bolt-on" header installation I have ever experienced.

Sounds like a cluster **** to me for a bolt on header

Pete,

I am so happy that we have you to put things in very succint and precise terms. I couldn't be any plainer than that or any simpler. You're the best.
