I had an Evo VIII and it put a smile on my face every day I owned it for 5 years. I had a momentary drop in IQ and got married and sold it for a Mazdaspeed3 "family car"

I'm currently deployed to Kuwait, but plan on getting back in 2012 and buying an Evo X GSR then doing some bolt ons right away.
Here's the current plan. I tried to pick the best performing parts with reasonably light weight and stealthiness:

-AMS Performance Intake (I don't think I'd see any gains from the CAI?)
-ETS UICP
-ETS FMIC (3" should do it)
-ETS LICP
-AMS Widemouth Downpipe (seems like the way to go, I can't find anything better)
-AMS High Flow Cat
-Cobb Tuning 3" SS Quad-Tip Cat-Back Exhaust (I like the look, weight and relatively quiet sound of this exhaust)
-Cobb Access Port (Looks like they have most of the tuning maps done for the 2011 computer now, so this seems like the way to go?)

Total in aftermarket parts= $4,134
Approx HP/Torque gains= +100

So my general questions are:
1. Does anyone see anything wrong with this setup?
2. Cobb's Stage 2 GSR map should work with the AMS and ETS parts I selected right?
3. Do I need to do anything weird with the exhaust setup? Like 02 sensors? Will the AMS stuff bolt up to the Cobb stuff ok?

Thanks all, have to keep my eye on the prize while I'm over here!

 

Had the exact same setup on my 08 GSR except the Cobb was the duel tip at the time. You will see some gains on the intake because the AMS intake has a slightly larger diameter. Eventually changed my Cobb exhaust for the ETS mainly because the right tip sat further in then the left. From the pics it looks like they did not fix that issue with the quad tip either. Cobb exhaust was quiet though.
