The ebay o2 housing comes in various forms like xs engineering, ss autochrome, megan, helix...etc. But, they are all made by one factory overseas. All the companies just sell the same thing with their logo on.

David,
On your ported/coated exhaust manifold - do I need to send my stocker in as a core? Can I send it in after I get the ported one to install so I don't have a long down time. Also, is it just port matched to the gaskets, or it it internally ported to inrease runner volume and flow? Thanks!!

my question is why doesn't someone make a new design and have it mass produced in the same way? why not make one that is fully three inch? and just have the wg piped into it... really all they'd have to do is make the main runner a bit fatter...
ok so i recognize that the stock donut gasket is the problem but like buschur doesn't even have a stock donut gasket on his dps... it'd be a perfect product for him to produce. megan's own dp uses a flex section, so does ttp. someone make one of these 3" for less than 500 dollars!

The manifolds we cannot keep in stock. We have tried to send ours out and then take yours back problem is most guys aren't in a hurry to do the swap. I just ordered 10 new manifolds because all of ours are out now and we have no cores being returned. Now we can't even do this as we have no parts here instock.
We port match the runners to the head and the collector to the turbine housing. The runners are smoothed inside enough to make for a gentle taper from each end.
trinydex,
Al asked me the same question. I hate to sell these quite honestly but there is no way in hell I can come close to reproducing them for the price. I even thought about making one that was really good and then having it cast. Problem with casting is the cost of the core box and time it takes. I could never make my money back on the part. China has its benefits and producing low priced parts is one of them.
I see a few companies that have a really large 02 housing but have not had a chance to test any of them. I believe Works is one and Indivia is releasing one but not out yet.
The other problem I see is going to a full 3" housing isn't going to do any good unless the downpipe flange is also 3". Making the entire housing 3" only to neck it down to less than 2.5" at the downpipe inlet won't do much if anything, if I had to guess.
These seem to be the best bang for the buck, as sad as it is to say.

I already have a tubular O2 and have thought about getting it coated, but I'm concerned that the coating could actually increase the likelihood of it cracking by trapping the heat in the metal. I thought the issue with cracking has more to do with heat fatigue than corrosion.
Is this a valid concern, or would I be better off getting it coated? (I'm more worried about it cracking then underhood temps or gaining a little power from the coating)

If you have it coated inside and out then the coating will keep much of the heat from ever getting to the metal of the 02 housing. It will just flow out into the downpipe.

We coat the housings inside and out. I believe this give better protection.
I think the instance that you are thinking of, when concerning causing cracking, would be if you wrapped it with thermal wrap. This is a no-no, when it comes to many parts as it does increase the likeliness of it cracking.
