OBX manifold users, take a look....
I, like many people on the forum, was an OBX manifold user. i read all the threads saying that they are junk, and like most people dismissed what everyone was saying. Now 5000 or 6000 miles later im typing this to show you what has happened and as a reminder to people who are thinking of buying one of these rag *** manifolds made out soda cans.
Heres the evidence......

I can't tell where that crack is exactly. Is it right where the turbo flange is? Can you take a pic of it further away, im just curious where exactly it cracked. Mine is still going strong now for a year and a half *knock knock*
Did your manifold happen to glow at all? either during cruise or beating on the car? I'm wondering if it has to do with some cars having higher egts or something like that.

What's the old phrase? You get what you pay for. It kinda falls into one of those categories, I think. Hope you get it fixed or find a better replacement.

It's probably 400 series stainless, if you can call it stainless. It will hold a magnet. The one I've seen would hold a magnet on one tube and the other tube would not. They must build them with whatever cheap stainless they get their hands on. Did you heat wrap the manifold ? That would explain the rust and probably why the thin crap stainless cracked so quickly.

Most of greddy's **** is garbage so that's no surprise.
Stainless manifolds are going to crack regardless. I dont care who made it and how well it is braced.
You want something that ill hold up, go cast or make your own out of schedule 40 piping.
However, 6000 miles is pretty good. I'd say you got your money's worth out of it.

Mine was right around $100 back in feb 07. but it's ssautochrome, I'm not sure if there is a difference. I always thought they were all from the same place, but I read on here somewhere that the ssautochrome ones were better built then the obx ones. Not sure if that's true or not, but mine has held up fine for about 2 years now.

but it's OK now... it's been VERY welded up and braced all over, so I don't see myself having any issues in the future.

Will work for horsepower
Knock on wood but ive been running a cheap manifold for over 5 years, i milled all the surfaces and made it fit well and so far i havent had any problems.
500H/p and running 10's and no cracks and it has been red before, i also black heat coated it and its not rusting.
But im going to build a new manny just becouse and i know its just a matter of time before i need a new one!
I have a mix of expensive parts and some cheap parts but i make sure the cheap parts are working properly and keep an eye on them! So far so good.

I just had a look at my OBX which I recently purchased due to a tight budget. Those cracks are a design flaw in my opinion. Where the two runners meet, they were cut and a piece of flat metal was welded only on the outside. If you look down about 2" from the T4 flange you can see what I am talking about. I am going to get mine welded on the inside, then reinforce the entire manifold and make up strong turbo brace. That way there is no weight on the manifold, hopefully it will last alright.
The manifold I got also had a warped T4 flange, which I am disappointed about... I am unsure if I can use it.
No fitment issues on my RHD FD thought. The wastegate runner has a good amount of room. However, we are going to modify the manifold with two synapse 40mm gates.
