***UPDATE***
Been a while, been really busy with school and work.
I have two weeks off school now (although I am being sent to lovely Bakersfield all week so that cramps my schedule) and I am back on the modding project.
I finally crawled under my car (and into the engine bay) and removed my downpipe. I will install the 42dd one tomorrow as I have dinner plans tonight, have to clean up and go.
Guys (and gals), this is really simple. Simple thanks in no small part to plac and his DIY video and many posts on this subject. All I needed was his condensed video found here.

I was apprehensive, I fully expected to run into an issue or not be able to manage it (epic pessimist). But with my wife holding the flashlight and spotter mirror getting the front most top bolt on the turbo was almost a breeze. All the others are a cake walk. If you have any mechanical aptitude and know how to use a wrench this mod is easy to do with simple tools. 2-3 hours your first time, no problem.
Took me about an hour to remove the OEM pipe, you DO have to remove the battery and the battery tray to have room to fit the socket wrench and yes you need a LONG extension (around 10-12") and a swivel socket or swivel adapter. The nuts on the turbo end were tight, had to use several blasts of BP Fabulous Blaster I grabbed at O'Rielly
(Link) to keep them from binding and breaking.
Install was fairly simply, just reversing the steps. And I already had all the right tools spread out LOL To make my life easy I only assembled the front two pieces of the 42dd downpipe off the car. Bolted it up to the turbo than installed the rear section on the car. One fitment issue, the rear section would not line up perfect, I had to really torque the bolts down to force the flanges to mate up and seal. After doing this I noticed the rear pipe was stretched on the hangers due to this mis-fitment. I will just have the exhaust shop realign the new pipes on my custom exhaust so the hangers are not stretched. Here's a picture of what I am talking about.
Here is a shot of the whole thing installed, the black finish with the copper gaskets is awesome. Of course only the techs at the dealer will ever see it LOL
I just installed the 42dd spacer and one non-fouler on the 3rd O2 sensor for now, I'll need to order another angle spacer for the #2 sensor and then see if I can't tune out the CEL.
I took some video of the stock exhaust sound and will take some after just changing the DP as well and post later. I got a worm drive clamp for the turbo pipe as suggested by plac and took the clamp off the intake as well to do the same, but couldn't find a clamp to fit and don't have the right type of vise grips to put the old one back on. LOL So, I won't be able to put the intake back on and start the car until next weekend when I get back.
Now I just need to make my appointment to get flashed to Stage 2 and then have APR build me a non-testpipe file because I want to try to work out the kinks of CEL free CBFA downpipe setups. I have lots of data logs of the O2 sensor readings at stock so we shall see.
But, Stage 2, here I come!!!!!! :burnrubber:
