I can't do a before and after. The wastegate pipe on the OBX is completely broken off. However, I can compare to the stock dyno sheet I have to cross reference. Before I do anything tomorrow, I will try to clean up the welds some. If this makes it to production and AMM, the welds will be clean and top notch.

wow, looks nice!!! subbin
If it's the same guy who welded the manifold shown, the last thing you wan't is it to be TIG welded.

Please know that I don't intend this to be rude, but constructive. I'm over 42 shop employees at the company I work for, 16 of those employees are welders. If any one of our welders produced those type of welds, he would be fired on the spot without any questions.
Not a bad design, excellent price.....now find someone else to weld it. If you do, I predict they will sale like hot-cakes.

Thanks for all the kind words and opinions. When I went into this, I basically told him, "Make me a manifold. I don't care how pretty the welds look, just so long as it works."
Well, knowing now that there are people who are interested, I guarantee the next one will look times better. I just need to get this one on and drive for a bit, then the next step would be building one more to sell to someone else to test it right along side myself. After all that, should be able to mass product a damn good product.

and will tou be offering it with a stock turbo setup, or GT28RS, with internal WG and egr still there(didnt see it in the prototype)? and i kind of like how it looks and if the welds are ground down some, even better, if not heat wrap will cover it up. i can wait to see the results.

OBX pile of s*** is out. Gotta run to a parts store and grab some new bolts to mount the turbo to the manifold. It is coming along nicely, and at the moment, the only problem I can see is that a T3T4 turbo will be cutting it close to the bell housing. These revisions will be made.

what is there to say...find a better welder... the design itself is good..although the collecter looks kinda weird...but ya if this ever gets cleaned up i may even buy one..so long as it is a direct swap for the obx...i dont wanna get another custom Dp made
Those welds are going to crack. I'm a welder, so I know. Those welds were laid WAY too cold. There is no dig (penetration) on any of those welds. The welder was most likely burning through so he back off the machine so he didn't blow holes.
Its hard to tell cause of the ugly, but they look like they were with stick (arc).
The proper way to weld that manifold is by TIG with a Agron purge on the inside. The fit has to be VERY good because the first pass (root) is just going to be a fusion (no filler) bead. This means that the base metal is continusly melted together all the way around. The root is the most important pass, cause this gives you the welds strengh. Then after that add a cap pass. The cap does not need to wide nor high. A nice almost even cap is best. All this has to be done with a argon purge on the inside. The purge helps keep the weld clean on the inside and also lets your use higher heat as it helps the weld puddle from falling into the work. Its a little more in depth then my quick write up.
I wouldn't even try that until it has been rewelded.
