2.5 inch 1.6 NA "downpipe"

Is there a company, without getting too custom, that makes a turbo sized replacement for the NA downpipe? I'm talking about the second half of the header on the stock miata. I've had a hard time searching because I'm not sure what else to call this. I have my stock piece bolted to the Greddy turbo downpipe. But it is rusted to the stock cat, which I want to eliminate, and the two bolts on the back half of the cat are buggered and don't bolt to my cat-back exhaust very well, creating a huge exhaust leak.
My catback is 2.5 inch Racing Beat so I'm trying to avoid purchasing any pieces I don't need. Also I'm a year away from my miata being emissions exempt so no need for the cat anymore.
I guess I'll need two pieces, the piece between the downpipe and the cat, and then a straight pipe for the cat. Can I get some "1.8" style pieces here? (I know the 1.8 uses a different cat right) so that I don't have to upgrade again when I go 1.8? Thanks for the help.
This one is cheap and I think what I need, but stock size:
More Information for KLARIUS 301541

I'm a cheap bastard too.
Anybody ever seen one of these?
OBX REPLACEMENT DOWNPIPE FOR MIATA MX5 DSM 4Bolts TURBO
Does it actually fit? Any good? The picture makes me nervous, flange doesn't look right and it also looks like a serious cheater bend. And, well, it's OBX.
OK, flame away, I asked for it.

edit: Also, I think its just the picture angle but the flange doesn't look too off when I compare it at the same angle to the stock one I have lying around.

Resurrecting this thread from the (possibly should have been) dead So... It looks like I've become the guinea pig.
It's an impressive looking, shiny pc of metal, but unfortunately, it doesn't line up with the output of the GReddy turbo. (TD04 15G?)... It seems to be a larger overall flange.
I was hoping it would be plug and play (oh, and it's fat, so you need to remove the manifold and all...
Perhaps the "DSM" reference in the ad suggests it's intended for those running a Mitsu turbo on the GReddy manifold? Unless there's a second 1.6L GReddy kit out there...
For now I'm going to cut off the flange from my Spare Greddy DownPipe and see how off the alignment is, perhaps I can fab something up to make them align...
Vendor offered me a refund if I just ship it back... but it's so shiny and pretty. (and seems reasonably fabricated.)
