Josh,
You're right about the explanation - ha ha ha!! In the UK we're blessed with a law that says cats are required on all vehicles registered during or after september 1992. I have a 1991 Legacy GT wagon and also a 1990 1.8 GL wagon. The 1.8 never a cat on it from new and the GT I don't know cos it only came into my ownership late last year without any cats. I've since replaced the decatted exhaust on the GT for a much better flowing job made by Mongoose.
I'm making an assumption (albeit a sound one based on my subaru workshop manual) that the manifold (collector?) on your 2.2NA is the same as my 1.8 variant. On my UK car it had a silencer in this part and not a cat. I think the cat will be the one on your mid pipe as you say. I did change the downpipes (it's not really a manifold I suppose) for a custom stainless job at the difference was amazing even on the puny EJ18. Unfortunately, after an incident with a flying truck tyre the place that fixeed my car replaced the downpipes with a factory standard job and binned my stainless lovelies (bast##ds)!!! Anyway, the O2 sensor is not on the collector (at least not on my car anyway). However, it can be on the GT car depending on age (it is on mine).
I think your question is about the exhaust joint on NA and turbo - if they are the same place? I can't say for sure short of taking the mid pipe off both cars. I can, however, compare my manuals with dfullerton's (he has the 1992 workshop manuals) to see. I take it you're trying to put a turbo exhaust onto your NA??

Exhaust
yeah.....I'm considering.....or looking into turbo kit for my car. I won't probably do anything unless I have another car.......so I have a backup driver......plus I'm going to look into getting a house some time in 2003....depending where I end up after my last rotation at work.
I'd sooner not have to do the exhaust if I do it now....and then have to do it again later.
I'm going to an engines class this week.....I've learned some stuff about N/A to turbo conversions, and some stuff about turbo's and stuff.
I'll write-up some stuff when I get back in town.

I think we got a little side tracted. Is there any horsepower difference from stainless to mild steel.

Exhaust
Doug, an exhaust is an exhaust. Given two systems with identical physical geometric parameters (pipe bore, bend radii, muffler stuffing, welding consistency etc) I seriously doubt there will be any noticeable (if any at all) power difference. For the seriously technically oriented I suppose you could consider parameters like specific heat capacities and thermal resistance of mild and stainless - where one may hold heat than the other and hence improve gas flow. Without digging out reference on these parameters I would surmise that there is little difference in even these material properties - think what the difference is between a stainless saucepan and a non-stainless one...
