Mod list question
I am compiling parts, I have...
Drop in
Test pipe
Catback
1000cc
aem fuel pump
3 port
I plan to install all of this and get tuned at RRE for e85/91. I live in cali, so I want to be able to easily convert to stock CAT and pass carb.
So here is the question..
Would it be worth is to do a short DP, or a long DP, or should i just leave it stock?
and...Would it be beneficial with these mods to get a cone intake? or should i stay with the drop in?
I plan to not upgrade further for a long time. thanks in advance. 2011 GSR

If you leave the stock downpipe you're sacrifing some performance but you won't have to go through the trouble of switching downpipes every year.
If you get a short downpipe, you get some added power from your tune, but have to switch pipes every time you go in for emissions inspection, which is a hassle and depending on your mechanical skills is a 1-3 hour job.
If you get a full downpipe, you'll make a little more power than you would with the short downpipe (depends who you ask, have seen plenty of people here who are convinced it makes a negligible difference) but you need to switch downpipes every time you go in for emissions inspection, and with the full downpipe, it's awful. Removing the downpipe at the turbo is much different than removing it at the O2 housing, go check out a DIY guide to see what I mean. It is not fun and will take several hours with access to the right tools and a lift, even longer if you are doing it at home.
Of course, you could pay someone to do the switch, but that'll be pricey, especially with a long downpipe. Personally, I'd get the short downpipe if you need to make that switch and are willing to do the work, and that's coming from someone who has installed/uninstalled both short and long downpipes. Also, keep in mind that depending on how the emissions testing is done (I'm not from cali so I'm not familiar with the process) when you switch you might want to also reinstall the stock catpipe/testpipe along with the stock downpipe as doing so would let you have all of the factory cats on the car for testing.
As for the filter/intake, if you have the extra money, I think you should spend a little more to get a full intake rather than a drop in. It'll make a little more power and won't needed to be upgraded later, even if that's not in the near future. Plus, for what it's worth, it'll look and sound better than a drop in.

On the stock turbo, you're not losing anything by sticking with the stock downpipe. If you have to swap stuff out to pass emissions every year, I can see no justification to put an aftermarket DP on.
A drop-in filter is also completely fine, unless you want the noises associated with an open element intake.

The evo x does not have a cat in the downpipe, so unless you go with a bigger turbo don't bother going with an aftermarket downpipe.
To pass emissions you will have to swap the test pipe out and put the stock cat pipe back in, not a very hard job, only 4 bolts and an o2 sensor. If you want a fuel pump, I recommend walboro, and also pick up a UICP while you're at it, won't affect emissions but will greatly improve throttle response when building boost.

Thanks for the responses.
Yes, I know the cat is not in the DP. After reading your responses Ill just leave the DP stock.
Ok, Ill look into a UIP.
One more noob question I cant find in a search...
I really like the K&N Typhoon kit. If I got it, would the UIP that is included do the trick? OR should I invest in a legit UIP? and would it be ok to go ahead and install it for a month or two until I get all parts compiled and tune it?

While I'm not a fan of K&N anything, a pipe's generally a pipe. It'll do the job any other UICP would do.
It uses the stock MAF housing, so you're fine to run the intake and UICP until you get a proper tune.
