when I got my last car BAR'd (98 RS w/ 06 WRX everything) I told the guy exactly what I did to the car and told him it was running off the 06 ECU etc they'll see that anyway but you know..
You will want to look as stock as possible. Stock cats a must. Stock catback highly suggested. They won't notice the vf39 so don't worry about that. TMIC is totally ok thats stock on suby's if he gives you **** explain that. I would try and ditch the CAI for a stock intake just to make things go by smoother.
What they'll look for when they plug in is to make sure your smog sensors are working. On my car there's something like 6 of them. FLI told me as long as 3 are working thats ok. That includes one for each o2 sensor etc. I had the charcoal canister hooked up, stock cats, both 02 sensors and a smog pump plugged in so my car flew with flying colors.
When I went (in like 08 lol) it cost 8.50 so worst comes to worse you find out whats wrong and do it again.

When doing a swap, it's helpful to swap the tanks if the cars are too far apart age-wise because it ensures that all the fittings and sensors are in place. With my '95 coupe, it would have been really hard to use the '95 fuel tank with the '04 emissions gear.
As far as the monitors being on, yes this is important too. Means the car needs to have been driven for a while after the last ECU reset basically but there are "methods" mentioned on this forum where you can help them engage faster.

Are you asking me? Yes, you can have a catback but you will want a stock downpipe and cat for the visit. Probably even a stock up-pipe depending on the shop. But you get what I am saying, right - you just want to look the part, and definitely NOT like you are trying to sneak something by. I would feel more comfortable with a stock exhaust system, but I wouldn't forgo the visit if I had an aftermarket catback.

as long as it "looks" stock, have your cats, you are good.
No colorful silicone hoses, no bs.
They will ask what motor you have, they will check you according to w/e they say you have.
So if you told them you have an 03 wrx engine, they will check for the 3 cats the best of their ability. They won't be able to tell if the uppipe has a cat or not, they will have to take your word for it if they can't find the "3rd" cat.
stock exhaust manifold is a must, best with the one still have heat shield that says subaru on it.
Take off your boost gauges etc, don't give them a reason to fail you.
Depending on the referee they may or may not smog you there.
Also check out the smog station ask him a few questions before going see how strict he is etc etc.
I bar'd my car without a dash =]
Helped a friend bar a ej207 with jdm ecu too

Hard to say. Best bet is stock that matches the parts. No CELs.

I wasn't planning to find a stock catback. I have two flow through mufflers in my straight through 2.5" RS exhaust. It should work perfectly fine sound wise, and yeah, I have the stock DP and will have a STI (catless) UP.

I have samco hoses from the donor, so looks like I'll be looking for oem Y hose and recirc hose.

Of course, people have been able to get away with many things, like the items that MonsterGC mentioned. I have heard many things like this in the course of my swap project, but for me personally I need to have reliable and predictable results when dealing with stuff like this. I used to drive several very smog-illegal cars around but that doesn't mean anyone else could or should. Everyone's results may vary, it just "makes sense" to limit the variables as much as possible.
Also your Samco hoses should be fine if they are black. Otherwise, lose them. I put black tape over the white "Samco" labels, or just take them off with sand paper.
To the OP: I am insanely jealous of you, that car is gorgeous. My favorite body made my Subaru. It looks nice, but I would lose the blue radiator hose, the cold air intake, and make sure there is a stock BPV on the I/C. The I/C should be okay but it would be even safer to put the '04 unit on there for the test. Put all the heat shields on the turbo and make it look nice.
The way I look at things like that is this: it's a little bit of work that will eliminate the possibility of an annoying conversation. It's easier now because these cars are getting older, but for example, I swapped all the "blue" parts for "black" parts under my hood, and am going to eliminate the name on top of my I/C just because I never want to talk to a LEO or smog guy about it. That's all.

Yours should be fine dude. Just run the stock DP and UP until after you BAR.
But you could probably borrow a stock set up... I think maybe Jeff has one that's cut down for the RS.
Basically... as long as your wiring is clean and you have all your sensors and cats where they should be... you'll be fine.

BUMP
Looking at the Uppipe yesterday it looks like it's a catless STi one, which is not going to work. I bought a STi one thinking this one was aftermarket, but that won't work because of the EGT probeneeds to be there. I'll see if there is a bung for it, if not, maybe I can just have the bung put in.
Otherwise I'll be hunting for a catted WRX one, and will have to go catless later.
Stupid EGT sensor doesn't exist on the STi. When people gut their cats, do they reuse it?
People are nasioc seem to feel the EGT can melt and mess up the turbo... but they are morons, so I can't take anything they armchair seriously.

It looks like that, a bit crude looking and dark in color. Flex joint just like that, and no cat.
I have this other STi one that does have the heatshield on it, maybe just have that modded to take an egt?
Where do people put aftermarket EGTs?

Hey gagan, I have a a few stock wrx catted up pipes if you need one!!
Also people normally put the egt probe right after the header flange on the exhaust manifold. Generally on cylinder 3 or 4
