not really sure where this post belongs, sorry, but i figured id get a fair amount of attention here, and this is where I normally post.

So here goes, I purchased this OBX manifold two months ago, and ever since then, it has needed more weld jobs than I have had to fill up my gas tank. It has just gotten to the point where im done with it and I cannot stand it anymore.

heres the view from the top, the red outlines show all the cracks that had to get rewelded.


and from the bottom, its no differant story.


where all the pipes meet? no differance.


since i couldnt weld underneath bolts, i even had to weld inside the pipes.


continuing on...

my car sounds like a lawn mower because of this crack.


and of course, the crack wraps around to the top.


im no fortune teller, but this small thin lined flaw looks like its a crack to be, a future of welds awaits this manifold.


this is why i want no more part of this manifold, look closely, the pipe is cracking.


so in conclusion, this manifold is absolutely terrible. it has been nothing but a nightmare since the first crack. the welds looks absolutely amazing, but of course, looks can be decieving. I hate it, thanks for reading. post this post anywhere you find someone looking into buying an OBX manifold. Let someone benefit from my mistake.

Sorry to hear that. No refund or anything?

I know a couple people that run OBX manifolds on their Miata and no problems.

 

that manifold looks like its got some vd....

 

moved to "Parts Review" since it is a review, isn't it?

 

was the manifold new? are you stock engine?

just wondering, because OBX SEEMS like a pretty good brand (have had no experience with them myself). and a new manifold cracking like that seems strange ... doesn't heat cause the cracks?

odd...anyway, sorry about your luck with that.

 

The manifold should be resistant to heat. I mean, it's only hot exhaust gases coming out of it, lol. But to answer your question, yes, heat can cause cracks.

 

obx has been a ****ty company.. dont ever get there short shifters for 240sx.. they tend to kill tranny's lol also i had cold air intake from them also failed should have just gotten aem back then and b&n for short shifter
