Narrowed down list for intake and turbo-back, but still can't decide.
I just went with drop in filter with agp hard pipe intake I made same power as my friend with his aem, and its a sleeper specially when the highway patrol ask you to open your hood, for turbo back I went with T1R 76s cat back exhaust a little pricy but I got mine black friday so I got it for a very good deal, its louder than stock, but not too loud that you get attention, quality is not bad,really nice throaty sound at WOT, no drooning sound inside chek out you tube, ams widemouth and RRE rallye test pipe with CEL fix from pep boys(this is a resonated test pipe with a cat heatshield welded to it so it looks like a stock cat if you look at it) I have a mr also and yes you want to pick the right exhaust bcause of the SST if you pick a loud one it will get a lot of attention, far as the intake goes the stock set up is pretty effiecient already all you need is a high flow AF and replace the rubber intake with a hard pipe if you like to keep it low key
so good luck
so good luck
Now, THIS is how members should post a "help me decide" thread. You've told us what you want, what's important and laid out the pros/cons (in your opinion) of the products you are considering. If only other members could follow your path 
Onto your questions.
For the intake, they'll all perform nearly the same...to be honest. Especially since you're pairing them with the Cobb AP. They are all good products, so you really can't go wrong. Price should be a consideration in this case. Also making sure there is an AP map for the intake is important. Finally, the UICP in the Injen kit is nice to have since the UICP is the "hot" pipe on the Evo X and it will make a nice impact in throttle response and possibly a small bump in hp/tq. That would be my choice. Or, buy one of the other intakes and get an UICP on the side (many members like the Nisei one piece). The UICP is a good mod to get.
BUT, unless you have much bigger plans for mods in the future, you don't need an intake. A drop-in filter will give you the same performance bump for the simple mods you have listed. If you want the turbo "sound" then you'll need the intake, but just know that it won't help on the performance side unless you plan to do more with the car.
For exhaust, again it's a toss-up and all of them are good products. The ETS exhaust is loud, so that might not work for you. I would choose between the Perrin and AMS exhausts, and would probably go with the Perrin TBE because it's less expensive than the full AMS exhaust. Both of them sound good. The advantage of the AMS downpipe is really only noticeable if you plan to upgrade your turbo. On the stock turbo, you'll see little to no gains.

I do want to hear the turbo and bov more which is one of the main reasons why I am considering the intake over a drop-in.
For the exhaust, you mentioned the ETS, AMS, and Perrin but do you have an opinion on the Cobb?
what do you mean by "stay the same"? I just installed mine and it's in the same locationish and is the same unit.

ETS uses the stock MAF sensor HOUSING, AMS replaces that housing with the piping and includes a flange for mounting the sensor. The new piping is bigger diameter, ETS has it bottle down to stock ID whereas AMS keeps the same diameter throughout. Take that info as you will, but the AMS will require a tune because of this change in ID of the MAF sensor housing.
Thank you for the detailed response. I hadn't given much thought to the UICP and thought that Injen was including it more for bling than anything else.

In the end, all of these products you've mentioned are solid products and are supported by great EvoM vendors. You would be happy with just about any combination of these parts and will see essentially the same gains (within 1% of each other) and it really all depends on the tune...and you're using an AP which will even things out since the AP provides a safe tune
My 2 cents. I have the Injen, intake and UICP combo. The build quality is top notch and is expected from Injen since they are known for their intakes. Price might be high listed but I'm pretty sure you can get it pretty low by PMing some vendors here on the board. I've made considerable power with this intake. The good thing about it also is that it doesn't fudge up your MAF like the AEM ones do. I think for an intake and UCIP it is a steal. I know Nanji, a well respected tuner in Socal highly recommends this intake for all the tunes he does. He says it makes the most power and is easiest to tune. PERIOD. If you're looking into getting a custom tune with the AP in the future, I'd go with the Injen.
Well looks like your on the right track with all the research you've done 

I went with Turbo XS TBE because of the price, and AEM intake because it fit with the Cobb flash and i liked the idea of blocking out as much heat as possible.
Im very happy with both
Good luck! post up with what you choose!!
