Basics I can give....
CNC Freeze-off or PB Blaster...that is your friend. Good idea to have a breaker bar handy just in case.
The heat shield has 10 or so bolts, some of them hidden. My replacement GS one has 3 lol.
the stock DP has a hidden bolt 1/2 way between the turbo and the bend at the bottom. Your aftermarket will not have that.

Thanks alot for the help. downpipe comes today, so I think I'm gunna go ahead an start taking off heat sheilds. If it looks pretty easy for my skill level I'm gunna go for it. I'm thinking I should be able to do it, I'm pretty good at learning things as I examine it and work with it. Chances are I'll order aftermarket shields with christmas casshhh, rather buy heat shields then have to wait til christmas, then pay to get the DP installed...
Dp installation isn't hard.
Remove the heat shield.
(some people remove the intercooler, not necessary but if you want to, go for it... For more room obviously)
Loosen the 5 downpipe to turbo bolts
Loosen the cat back bolts
Undo the hanger
Unthread the o2 sensor.
Undo the 5 dp to turbo bolts completely.
Get under and hold the dp while you remove the cat back bolts.
Reinstall just go backwards.. Use a new gasket for the dp to turbo and a factory gasket and cat back bolts.
i havent had a heat shield in 3 years...

The downpipe was relatively easy when I did mine. Probably took me a total of 30 minutes if I was just doing the downpipe install. It makes it easier if you have two people one underneath the car and the other above holding it on the wastegate. I found if you don't have two people you risk the bolts stripping from not being aligned properly.

The only biatch is the one DP bolt thats closest to the TMIC/tranny side. You have very little room to work with and almost no way to get in with any kind of breaker bar, etc. A lot of this is due to the size of the stock DP heatshield as well. Finally figured out to use a simple 1/4in socket...yes the little guy. And pulled it right off...even on a 115k stock DP.
