Exhaust Gaskets??
I am doing an evo9 turbo swap, and i am trying to figure out if i should keep the same exhaust manifold gasket or get a new one?? The one that was on the car was the OEM 4 layer gasket.
Also do you guys use a gasket for the megan o2 housing to the downpipe?? And what kind of gasket should i use?

agreed, I ended up replacing my ex. manifold gasket after having it off the car like 5 times just for piece of mind, but there were no telltale signs of exhaust leaks from it even at that point.
However, I would consider replacing the one between the turbo and o2 housing, I have had that one fail from not replacing it... but again, it failed after having it apart I'd say 2 or 3 times. I'd buy a new one of those
If its the new Megan downpipe you can use a stock "doughnut" and it will seal up good, if its the older style like I think you have (03-04) the supplied doughnut can be reused just keep an eye on it, mine never did actually fail either after more times removing than I care to recall (lol) but it does crunch down alot when you first assemble it so just keep an eye on it

I have taken off my exhaust manifold probably 7-10 times now. And I have never replaced the gasket. As long as they look like in great shape there shouldnt be any problems reusing them.
As mentioned earlier follow the correct pattern removing and installing the manifold. Removing start outside going in. Installing start inside going out.
