Re: Wahts wrong with the OBX manifold (tx99gsr)
bad material....very prone to cracking (ie. your wastegate falling off and landing about 500 ft behind you before you even realize that loud noise was from that). be patient and purchase yourself the RevHard equal length...I believe the look the same...if that's what you want....or go with the InlinePro / RevHard manifold. I've heard RevHard cracking on rare occasions, but the InlinePro is cast so it's quality is top notch....PM Arturbo he sells them

Re: (TKERacer619)
FYI, because of a friend's experience and those posted on here, I decided against the OBX and just ordered one from Tinker219 aka LoveFab.

Re: (mike1114)
one or two re-welds doesnt bother me much.. as long as its still cheaper than others. my neuspeed 421 cracked and i dont blame the company really, as im sure it took one or two too many bumps/bottoming out.

Re: (XDEep)
The problem isnt the material per say. Its 10 gauge 304 stainless. Its the welding that is done the manifolds. When you have a TIG weld you have to penetrate the entire way through the pipe to make a complete weld. This must be done with Argon being purged into the piping being welded so that the inside AND outside of the piping is shielded properly. If this doesnt happen, "sugaring" will occur to the weld on the inside. The weld becomes nothing more than a cosmetic piece, and cracking will occur. The TIG welds on the manifolds are preformed by robotic machines, incapable of knowing if they have welded all the way through the piping or not, as well as telling if "sugaring" has occured. I have one of the sparkz racing manifolds, the welds are purely cosmetic and there is "sugaring" over the entire inside of the collector area.

ya i always wondered how people can tell if a weld has gone through, either too much or not enough. especially with those wierd pipe angles.

Re: Wahts wrong with the OBX manifold (tx99gsr)
I run an ss autochrome/OBX one on my sr20det. The walls are alot thicker than i thought they would be. Very nice unit, I have an hks2530 not a big turbo but bigger than stock and i have had the mani for 9 months and hand no priblems at all. I payed 280bucks. In the land of the sr20det where manis cost a grand or more i think this one is well worth the money. Only bad things is pulling the mani on an s13/sr20det is 100 times harder and longer to do than the onld hond ai had. Damn nissans

Re: Wahts wrong with the OBX manifold (tx99gsr)
The new designs seem very different from the older designs. I got one for our project car before I found out about all the horror stories. This one is supported on the bottom. From the flange to the collector, there are two supports. And the WG flange is much closer than the pics I see of the cracked ones. There's hardly any pipe there at all, just the WG flange. Hopefully this works out since it's on the car already.
On the plus side, we put the car on the dyno right after finishing it, and it put down 160.6 whp and 135.9 ft/lbs at 3psi, running way rich (A/F was around 10 the whole time). This is on a '00 Integra LS auto. Can't wait to break everything in, put it back on the dyno and tune it.

Re: Wahts wrong with the OBX manifold (AP-Signworks1)
I just bought the OBX Turbo Manifold for My Si and I will be welding two support brackets on the bottom of the manifold for support. I'll let you know how it goes. Thanks.

Can you show me where I can buy a revhard equal length? Somebody on here had an SI before that was making a bunch of horsepower with one, but I havn't found one for sale. Been thinking of the inlinepro one too, that's a nice piece as well.
