I've got an lsj header and dp, I'm going to see if my dealer will flash out sai, but can I through on that header and dp with my stock cat back no problem? will it bolt up just right? I'm asking because I don't wanna get it all on and then realize it's not gonna work. it's n 09. I'm eventually gonna get an aftermarket cat back but I just wanna know for now if the lsj header and dp will bolt right up to the stock cat back?

message me, I'll walk you through it. Should also be in my 2.2 reflash thread. It's not difficult, just a pain in the ass.

Friend came over so we got to it. Started stripping things off the engine like the coils, fuel rail, etc. Started removing all of the SAI components. Removed the SAI tubing and switching from the back. Removed the exhaust manifold and down pipe. When we got the exhaust manifold and down pipe off we got a little surprise.
There is a tube connected to the back of my cylinder head that has open ports and the cylinder head has ports for this thing in the back!! This is not on any other year SAI vehicle except for my 2009!! Here is a picture of that tube in a diagram. I was going to take a photo but my friend put it back on before I could get to.
It looks like this when the manifold is bolted up...the holes in the gaskets show you where this tube goes on the back of the head.
I quickly realized that I may have to use the stock exhaust and leave the SAI tubing and switch in the back and wouldn't be able to use the LSJ exhaust manifold or down pipe. After sitting for a few minutes and thinking about it... I decided that I could probably modify the LSJ exhaust manifold to accept this tube.
This picture shows where those holes in the gasket to accept the tube should be on my LSJ exhaust maninfold.
So I took my red paint pen and outlined it on the LSJ exhaust manifold.
Here is the finished LSJ exhaust manifold ready to accept the SAI tube bolted to the back of the cyl head. Should have taken a different picture because it is showing black where I cut it out. It took me 1 1/2 hours of using my grinder, dremel with a diamond bit, etc, to get this to work.
The LSJ exhaust manifold and down pipe are now installed. My rear 02 sensor wouldn't come out of my pipe, so I have to buy a new one tomorrow. I also had to modify the LSJ exhaust manifold heat shield because it wouldn't fit because of that tube behind the cyl head.

ha ha. you missed my sig I take it? ha ha. I've got the 09 1lt. and im talking about the little pieces that look like they're not as thick as the reast of the header where he cut. if you look at the jsl header in his pics, the grooves he cut out to match the stock are like not as thick, you can kinda see what I'm talkin about if you look at the center hole on either header and look how it's not as thick. if that makes any sense to anyone.

Yes, the casting is not as thick and can be cut.
I could probably write a few long paragraphs on how to handle it... but here are a couple of quick choices.
#1. Where the 2 ports are in the back of the cylinder head you could take the 2 ports in the tube (corresponding mating parts) to create a template for block off plates.
#2. If you install the tube you are left with 1 port at the end of the tube to hook up to the switch (big thing that sticks up in the back) and do a block off plate there. That is what I did.
#3. You can have the holes in the tubes welded shut.
#4. You can get an LAP non-emissions cylinder head.
To me, and why I did it, #2 seems to be easiest.
