Long tube headers
recent thread with a similar car. OBX are "made in China"....you get what you pay for and if the exhaust shop has to bang away to get them to fit, well you'll pay on the back end
If I were you I'd look at Melrose, TPIS or maybe EM (they're on ebay)

Yes. You've got a few options from headers. You can buy headers from a small company which will charge you a fortune because they have no buying power so they pay a premium for steel. You can buy from a large company that hires meth heads and toothless rednecks (I've toured these facilities), or you can buy from the Chinese which employs 12 year old girls.
I don't really care who gets my money, I just care about the value. The Chinese OBX headers are outstanding. I compared them side by side to the stainless works headers and they were very close in quality, except the Chinese obviously had robotic tig welding.
There is also the "Dyno Don" headers out of California that look like they were welded with a car battery and a coat hanger. Those are not stainless though.

Good quality welds, thick gauge stainless. The ports were opened up to a felpro 1405 with a nice entry. The flanges were thick and flat, no warpage. I don't see why the brackets would be an issue, they are mounted the header bolts using spacers. I find plug access to be very easy. I've also run the hooker long tubes on a C4 and also found plug access to be easy, but I see people complaining about them.
I don't know about the AIR tubes, so I can agree that could be a problem. The ones I have bought for other platforms (fbody) had no AIR tubes. I have a set of the shorty version (in stainless) that might go in my C4, or I might buy a set of the long tubes. Have not decided yet on that as it's just a street car.
I wouldn't ceramic coat anything. Go stainless. Ceramic coating dulls, turns to crap, scratches, etc. Stainless headers last forever. I have some SLP headers from the 90s in my shop that still polish up.

We can support child labor in China and the money that goes to the gov't, you know the gov't that is catching up to the U.S. in military technology
Who gets your money? Value + OUTSTANDING chinese headers = ???
Don't worry about Melrose headers, they don't have little girls fabricating their headers....save a couple of hundred
I hope you factor in the "cost of aggravation"

What cost of aggravation?
It's 2019. Chinese products are good. In many cases the manufacturing processes are far superior to stuff made here. The equipment is new, robotic controls, etc. US companies cannot compete because union thugs demanding outrageous wages and outdated equipment / manufacturing processes.
Between trade tariffs, investments in Chinese corporations, and the fact that we are paying American companies to import the goods I have no issues where the money is going.
Again, I'm running these on my Firebird. I have another few sets in my shop for other applications. I've used them, including their turbo headers in lots of other vehicles. Good quality.

Union Thugs or preteens/children working in a factory....I'll take the Union guys, the money they make they spend here. I'm confused here because you talk about superior manufacturing facilities (ie: robotics) and mention 12 year old kids working in Chinese factories

Have you seen videos of over seas manufacturing ? Interesting stuff. Sometimes it's a disaster, but many times it works out. We just bought a company in India that came with 35 skilled workers. They are very cheap, and work hard. Meanwhile, the lazy kid who can't get my order right in the drive thru window wants $18 an hour.
Have you installed OBX headers on anything?
I'll pay more for something if it's proven much better. Lay a set of stainless OBX headers next to a pair of Hooker and you'll quickly realize the "chinese crap" is much better.

When I bought headers, I can't remember the other brand but the builder suggested that in spite of the fact that TPIS was very proud of their headers, I should pony up and get them because of the size that would be best for my setup. Something about the ceramic coating would help heat control better so the parts don't bake as much, especially wires.
IDK about you but my hood is closed unless I am working on it so I really don't see anything until then. Also, I am not an aesthetics person so looks make no difference to me especially if it is under the hood. Assuming they have the 1.75 in primaries that I have (for performance) and assuming they are going to last (corrosion since I drive in winter when there is no ice), the only other things I need is to be able to install it and get to things with the least amount of effort. At that point, price wins.

OK. So you are into subsidy then? I'm not. If all things are equal, I'd buy US made. If they are not, I'm not into subsidizing them just because I can afford to. I could care less if the Chinese grind their kids up into the headers. Not my circus, not my monkeys.
All said and done, You'll probably come out ahead saving a few more dollars going the OBX route, if that is your goal.
But it will be more hassle installing with OBX, because its not just plug and play.
You or your muffler shop are gonna have to do some welding, and make the connecting ends, to get them installed.
You are also gonna have to make spacers for the bolt holes.(not a big deal.) But all that will cost additional labor dollars.
I took the easy route, and went with TPIS for my 85, which is about double the price for parts.
The TPIS are as plug and play as you can get, but my installer still bitched and moaned about the hassle.
With the TPIS, there is one plug port that's a little hard to get to, so I use accel shorty plugs for it. There is one pipe that is super close to the plug wire, and to prevent it from burning, you'll need to wrap it with something like those fiberglass matt wire shields, or use a ceramic boot wires (accell makes them).
You also have to dimple in a little bit one or two of the pipes with a screw driver, if you want to use stock bolts.
But the TPIS has 5 huge advantages.
-Its 1-3/4" instead of just 1-5/8". More flow.
-its got a matching front Ypipe to make the transition to the stock CAT a breeze. And yes that s a tight fit around the trans and starter.
- Its ceramic coated.
- And it fits perfectly, around other accessories. (for ex, you can remove the starter without loosening headers. and no problem getting access to the slave cylinder.)
- 3" diam from collector back.
I highly recommend the TPIS, as the first choice, if your budget will allow.
Id get the OBX over the headman, any day. On a stock engine, Headers really don't add that much power. So its barely worth it.,
But to get any power benefit at all, you really need to go long tube.
Don't worry about tuned (equal length), because it will be impossible to get a good fit.
But if you are doing headers for the purpose of power, you need to consider what your engine build will eventually be.
A smaller diameter header like 1-5/8" is just fine for stock or mildly improved engine. Going larger can actually reduce torque, because it reduces velocity.
However, if you plan to improve the flow of your intake (mini ram / stealth ram) and/or heads, and run hotter cam, stroke, or maybe Super charger, etc, that's really when you need headers, and the larger 1-3/4" pipes are the perfect size and can compliment the build and add significantly more power, and will be an essential part of the plan to reach intended power levels. I wanted, the 1-3/4" tubes, so that my header would handle the growth and evolution of my future engine builds, and they aren't excessively to big for stock either.. .
So if you plan to build your engine bigger down the road, don't waste your time with small 1-5/8" primaries.

What exactly wasn't fitting right? If I had to replace mine, I'd like to know. They have some scrape marks and I think a dent or two
I don't know which one it is but I have MSD wires and while some are a little close, none have burned but I am using AFR heads so not sure.
Interesting. I didn't dimple anything but IDK if they were different for the non AIR ones.
